Tomato | Plants

Solanum lycopersicum • Also known as: Love Apple

While *Solanum lycopersicum* (tomato) is primarily known as a cash crop, knowledge base excerpts highlight its integration into regenerative systems. It's utilized as a "cash crop" in no-till conservation farming systems, where specialized equipment facilitates its planting alongside cover crops like cereal rye. Tomato cultivation benefits from regenerative practices such as integrated nutrient management (INM), which combines organic amendments like farmyard manure with reduced inorganic fertilizers, improving yields and soil health. On-farm produced arbuscular mycorrhizal fungi inoculum has also been tested to enhance tomato growth, demonstrating dependency on beneficial soil microbes. Biofertilizers are explored as sustainable alternatives to chemical fertilizers, showing yield and soil health improvements in tomato systems, aligning with nutrient cycling and circular economy principles. Although not a nitrogen fixer or primary cover crop, its inclusion in diversified cropping systems, potentially alongside practices like cover cropping and reduced tillage, contributes to overall farm resilience and soil building. Farmer experience suggests that integrating organic matter sources like farmyard manure is key to optimizing yields in conjunction with nutrient management strategies.

Regenerative Trait Ratings

How These Traits Are Calculated

Trait dimensions are ordered clockwise starting from the top of the chart (12 o'clock position):

1. Profit Potential

Net returns per acre from yield, pricing, input costs, and labor efficiency

WHAT: Synthesizes gross revenue potential, input costs, labor requirements, and storage/marketing advantages into net profitability per acre. Captures the complete economic picture from planting to sale.

WHY: Not all vegetables are equally profitable. High-value crops with efficient production can return $10,000-30,000/acre versus $2,000-5,000/acre for lower-value options. Profit potential guides crop selection for maximum return on limited land and determines viable scale for farm businesses.

HOW: Scored via LLM synthesis of economics data (yields, prices, costs), storage advantages (season extension, value-added potential), and labor intensity. Exceptional (3.0): High yields × premium prices with moderate inputs and good storage (garlic, high-value salad greens). Typical (2.0): Moderate returns (tomatoes, squash). Limited (1.0): Low yields, commodity pricing, or intensive labor requirements (low-value greens).

2. Production Reliability

Weighted: yield consistency (60%) + disease/pest resistance (40%)

WHAT: Combines yield reliability (harvest consistency year-to-year) with disease and pest resistance to measure predictable production. Reliable vegetables deliver consistent harvests without catastrophic failures from pests or weather.

WHY: Market commitments and CSA subscriptions require dependable production. Unreliable crops that fail in bad years or require intensive pest management create cash flow gaps and customer dissatisfaction. Reliable producers allow confident planning and reduce input costs from emergency pest interventions.

HOW: Weighted formula prioritizes yield reliability (60% weight) for overall consistency, with disease/pest resistance (40% weight) to prevent total failures. Exceptional (3.0): Consistent yields across variable seasons with strong natural pest resistance. Typical (2.0): Generally reliable with some pest/weather sensitivity. Limited (1.0): Highly variable yields or severe pest vulnerability requiring intensive management.

3. Climate Resilience

Temperature and rainfall tolerance across diverse growing conditions

WHAT: Measures the breadth of climatic conditions where the vegetable produces successfully—temperature extremes, humidity ranges, and rainfall variability. Climate-resilient crops work across diverse regions and weather patterns.

WHY: Climate variability is increasing—unexpected heat waves, cold snaps, or drought periods can wipe out entire vegetable harvests. Resilient crops provide insurance against weather uncertainty and allow geographic expansion for market growth. This is especially critical for direct-market farmers who can't easily substitute crops mid-season.

HOW: Ratings based on the climate_adaptability trait documenting temperature tolerance and geographic range. Exceptional (3.0): Grows successfully in diverse climates (cold to hot, humid to dry) with wide hardiness zone range. Typical (2.0): Moderate climate flexibility. Limited (1.0): Narrow climate requirements (tropical-only, cool-season-only, humidity-sensitive).

4. Growing Ease

Weighted: establishment ease (50%) + low maintenance requirements (50%)

WHAT: Combines establishment difficulty (germination, transplanting) with ongoing maintenance needs (watering, fertilizing, pest management) to measure total labor requirements. Easy crops grow reliably with minimal intervention.

WHY: Labor is the primary cost for small-scale vegetable production. Easy-care crops allow farmers to manage more production area with the same labor, improving profitability. Difficult crops requiring constant attention, precise timing, or specialized skills reduce overall farm productivity and increase risk.

HOW: Weighted formula balances establishment ease (50% weight) for reliable startup and inverted maintenance intensity (50% weight) for ongoing care. Exceptional (3.0): Direct-seeded or easy transplants with minimal water/fertility/pest needs. Typical (2.0): Moderate care requirements. Limited (1.0): Difficult establishment or intensive ongoing management (daily watering, heavy feeding, constant pest monitoring).

5. Space Productivity

Weighted: yield per square foot (60%) + season extension potential (40%)

WHAT: Combines spatial productivity (yield per square foot) with temporal productivity (extended harvest windows from succession planting or season extension). Maximizes production from limited growing area.

WHY: Land is the primary constraint for vegetable farmers—especially those near urban markets. Space-efficient crops delivering high yields in small areas improve per-acre profitability dramatically. Season extension (spring tunnels, fall protection) adds bonus production windows when competing supply is limited and prices are higher.

HOW: Weighted formula prioritizes space efficiency (60% weight) for core yield per area, with season extension potential (40% weight) for bonus production opportunities. Exceptional (3.0): High yields per square foot (10,000+ lbs/acre equivalents) with season extension options. Typical (2.0): Moderate yields and extension potential. Limited (1.0): Low yields or crops unsuitable for season extension.

6. Multi-Benefit Value

Ecosystem services beyond harvest—pollinator support, nitrogen fixing, pest habitat

WHAT: Measures ecosystem services provided beyond harvestable yield. Multi-benefit vegetables contribute to farm ecology through nitrogen fixation (legumes), pollinator support (flowering crops), beneficial insect habitat, soil building, or erosion control.

WHY: Cash crops can either extract from farm ecosystems or contribute to them. Vegetables with strong multi-benefit value build soil fertility, support pollinators needed for fruit/vine crops, and create habitat for pest predators—reducing external input needs. Nitrogen-fixing vegetables (beans, peas) provide $40-80/acre worth of fertility for following crops.

HOW: Ratings based on the multi_benefit_value trait documenting service contributions. Exceptional (3.0): Significant ecosystem services (nitrogen fixation, heavy pollinator support, soil building, pest habitat). Typical (2.0): Some ecosystem contributions. Limited (1.0): Single-purpose cash crops with minimal farm ecology benefits.

Ratings are based on documented performance in regenerative systems, not conventional high-input scenarios. All traits assume integrated management practices focused on soil health and ecosystem services.

Climate Suitability Assessment

Will this plant thrive in your climate?

IDEALLY SUITED

Köppen Zone: Aw (Tropical Savanna), Cfa (Humid Subtropical), Csa (Hot-Summer Mediterranean), Cwa (Monsoon-Influenced Humid Subtropical), Dfa (Hot-Summer Continental)
USDA Zone: 6a, 7a, 8a, 9a
Australian Zone: subtropical

Tomatoes achieve optimal growth and yield in climates with long growing seasons (180-250+ frost-free days) and summer temperatures consistently between 70-90°F (21-32°C), conditions met across Köppen zones Cfa, Csa, Csb, and regional zones like USDA 6b-10b, Australian subtropical, and parts of EU continental. These environments provide ample heat and daylight for robust vegetative growth, excellent fruit set, and full ripening, leading to high yields and quality. While adequate rainfall is beneficial, supplemental irrigation is often crucial in drier periods or very hot summers to prevent stress and ensure continuous fruit development. Disease management is still important, especially in humid subtropical areas, but the extended warm periods minimize frost risk and allow for a prolonged harvest season, making tomatoes a highly reliable cash crop.

ADEQUATE

Köppen Zone: Af (Tropical Rainforest), Am (Tropical Monsoon), BSh (Hot Semi-Arid (Steppe)), Cfb (Oceanic (Maritime Temperate)), Csb (Warm-Summer Mediterranean), Cwb (Subtropical Highland), Dfb (Warm-Summer Continental)
USDA Zone: 5a, 5b, 10a, 11a, 12a
Australian Zone: temperate
EU Climate Region: atlantic, continental

Tomatoes can be grown successfully in climates with moderate growing seasons (120-180 frost-free days) and summer temperatures ranging from 60-80°F (15-27°C), as found in Köppen zones Cfb, Dfa, Dwa, and regional zones like USDA 5b-6a, Australian temperate, and EU Atlantic/continental. While not as ideal as warmer climates, these conditions allow for reasonable yields, particularly with early-maturing or determinate varieties. Challenges include cooler summer temperatures that can slow ripening and increase susceptibility to diseases like blight, especially with consistent rainfall. Season extension techniques (e.g., row covers, early varieties) and careful management of planting dates to avoid frost are often necessary. Water management is also critical, as dry spells can occur, impacting fruit development and yield potential.

NOT RECOMMENDED

Köppen Zone: ET (Tundra), BSk (Cold Semi-Arid (Steppe)), BWh (Hot Desert), BWk (Cold Desert), Dfc (Subarctic), Dwa (Monsoon-Influenced Hot-Summer Continental)
USDA Zone: 2a, 3a, 3b, 4a

Tomatoes are not recommended for cultivation in climates with very short growing seasons (under 120 frost-free days) and cool summer temperatures (consistently below 65°F/18°C), or in regions with extreme cold or heat that prevent reliable fruit development. This includes Köppen zones Dfb and Dwb, and regional zones like USDA 3a-5a, and Australian temperate zones with very short seasons. In these areas, the limited frost-free period, high risk of frost damage, and insufficient heat prevent most tomato varieties from maturing properly, leading to very low and inconsistent yields. Technical feasibility is extremely low without significant intervention such as heated greenhouses, making it economically impractical for regenerative agriculture. Alternative, more cold-tolerant or faster-maturing crops are better suited to these challenging environments.

Better alternatives for these "not recommended" zones: Bush Bean (shorter maturity, tolerates cooler conditions), Radish (very fast-growing, cool-season crop), Spinach (cool-season leafy green), Kale (very cold-hardy leafy green, tolerates frost)

Note: Zones listed above represent climates where this plant can produce reliably with reasonable management. Climate zones not mentioned would require intensive climate modification (greenhouses, extensive infrastructure) and are not economically viable for regenerative agriculture purposes.

Soil Suitability Assessment

Which soil types work best for this plant?

IDEALLY SUITED

Loam Soil

This plant thrives in these soil types without requiring amendments or remediation. Natural soil conditions support optimal growth and productivity.

ADEQUATE

Clay Soil, Rich Soil, Sandy Soil

This plant performs acceptably in these soil types with moderate, manageable remediation such as pH adjustment, compost addition, or drainage improvement. The required amendments are practical and cost-effective for regenerative agriculture.

NOT RECOMMENDED

Acidic Soil, Alkaline Soil, Desert Soil, Rocky Soil, Saline Soil, Wet Soil

Growing this plant in these soil types would require impractical remediation such as complete soil replacement, extensive amendments, or cost-prohibitive infrastructure. These conditions are not economically viable for regenerative agriculture.

Note: Soil suitability assessments focus on remediation requirements. "Ideally Suited" means the plant generally thrives without the need for substantial amendments, "Adequate" means manageable remediation (lime, compost, mulch), and "Not Recommended" means impractical soil changes would be required. Climate factors like rainfall and temperature also influence success.

Seasonal Considerations

Planting timing, growth duration, and harvest windows

For tomatoes, begin seed starting indoors about 6-8 weeks before your last expected frost, aiming to transplant seedlings into the garden only after all danger of frost has passed and soil temperatures consistently reach at least 60°F (15°C). Direct seeding is generally not recommended in these climates due to the long growing season required.

Tomatoes require a significant period to reach maturity, typically 60-90 days from transplanting, depending on the variety. Harvest will span throughout the warm summer months and into early fall. For continuous production, consider succession planting by transplanting new seedlings every few weeks until mid-summer, ensuring they have enough time to mature before the first fall frost.

Tomatoes thrive in the heat of summer but are highly sensitive to cold. Protection is crucial in early spring and late fall. Utilize season extension techniques like row covers or cold frames to protect young transplants from cool snaps and to extend the harvest into autumn, pushing maturity as close to the first expected frost as possible. Avoid planting in late fall as they will not establish or produce fruit.

System Role & Multi-Benefit Value

Functional roles, integration strategies, and stacked benefits

Functional Role

Total System Value

While tomato's primary benefit is direct harvest value as a cash crop, its integration into regenerative systems amplifies its contribution. Practices such as no-till farming, as mentioned in excerpt, can improve soil structure and reduce erosion during tomato cultivation. Integrated Nutrient Management (INM) approaches, combining organic amendments like farmyard manure with inorganic fertilizers (excerpt), enhance soil fertility and nutrient cycling, contributing to improved soil organic matter and cation exchange capacity. Biofertilizers, as discussed in excerpt, offer a sustainable alternative, further boosting soil health and nutrient availability. By supporting these practices, tomato cultivation indirectly contributes to ecosystem services like carbon sequestration and improved water retention. Risk diversification is achieved by integrating tomato into a polyculture system, reducing reliance on monoculture and increasing overall farm resilience.

Integration Characteristics

Multi-Benefit Value: Adequate - Tomatoes provide nutritious food and attract beneficial insects, while their biomass contributes to soil organic matter and supports a thriving soil ecosystem.

Management & Care Requirements

Integration guidance, maintenance needs, and care practices

How to Integrate This Plant

Tomato (Solanum lycopersicum) integrates into regenerative systems primarily as a cash crop, offering opportunities for soil health enhancement through practices like no-till farming and integrated nutrient management (INM). Its role as a cash crop with services means it can be grown alongside practices that improve soil fertility, such as using biofertilizers or incorporating farmyard manure, as demonstrated in studies combining inorganic fertilizers with FYM. No-till equipment, including specialized transplanters, facilitates its integration into conservation farming systems. While not providing direct ecological services like nitrogen fixation or shade, its cultivation can be optimized using regenerative techniques that enhance soil organic matter and nutrient cycling. Tomato begins providing direct harvest value in Year 1, with its integration into more complex systems like alley cropping or food forests potentially offering cascading benefits as companion plants mature.

Integration Practices & Management

Regenerative agriculture integrates *Solanum lycopersicum* (tomato) through various conservation-focused methods, emphasizing soil health and reduced external inputs. Establishment often utilizes no-till practices, as seen with specialized no-till transplanters tested for cash crops like tomatoes. This approach minimizes soil disturbance, preserving soil structure and microbial communities. While direct seeding is common for many crops, tomatoes are typically transplanted, allowing for greenhouse inoculation with beneficial microbes like arbuscular mycorrhizal fungi to enhance early growth and nutrient uptake. Regarding integration with other farm components, tomatoes can be part of diverse cropping systems. Case histories indicate yield improvements when tomatoes are grown alongside other horticultural crops, benefiting from biofertilizer applications that enhance nutrient cycling and soil health. While the provided sources do not detail integration with grazing or specific termination strategies beyond natural winterkill or crimping for cover crops, regenerative principles suggest careful timing and management to avoid soil degradation. Fertility needs can be met through enhanced soil organic matter and microbial activity, potentially supported by biofertilizers or locally sourced amendments, rather than solely relying on synthetic fertilizers. Competition management would involve appropriate spacing and potentially the use of cover crops or beneficial companion plants, though these are not explicitly detailed for tomatoes in the knowledge base. Succession planning in regenerative systems would involve rotating tomatoes with other crops to break pest cycles and improve soil fertility over time.

System Enhancement Value

Beyond harvest: ecosystem services from regenerative cash crop practices

Ecological Service Contributions

Tomatoes, while not a nitrogen fixer or significant shade provider, can contribute to system value through their role in polyculture systems and by supporting beneficial insect populations. Knowledge base excerpts and highlight tomatoes grown in polyculture gardens alongside other vegetables and companion plants like marigolds and basil. This integration can lead to improved soil health through the addition of organic matter from crop residues and the use of diverse fertility inputs like comfrey, chicken manure, and compost. While direct pollinator preference for tomatoes might be low compared to native plants (Excerpt), their mass flowering can still provide a nectar and pollen source, particularly in agricultural landscapes where native options may be limited. Furthermore, the cultivation of tomatoes within diversified systems, as indicated by Excerpt referencing biofertilizer use, can enhance nutrient cycling and contribute to a more circular economy on the farm. Their inclusion in multi-crop systems can also lead to improved soil microbial activity.

Ecosystem Service Contributions

Environmental contributions: carbon, pollinators, wildlife, and water

Carbon Sequestration: Tomatoes are annual crops with relatively shallow root systems and a short growth cycle, thus their direct carbon sequestration potential is limited, primarily contributing to soil organic matter replenishment through their biomass decomposition.
Pollinator Support: Medium. While bumble bees may prefer native plants over tomatoes (Excerpt), tomatoes can still provide a source of pollen and nectar in agricultural landscapes, contributing to overall pollinator resource availability, especially when grown in polyculture systems (Excerpts,,).
Wildlife Habitat: Minimal. As an annual crop, tomatoes offer limited long-term habitat for wildlife beyond providing a potential food source during their growth and fruiting stages. Their primary role in habitat is through their integration into more diverse farm systems.
Water Quality: Not applicable

Why farmers use this plant and additional resources

Why Regenerative Farmers Use This Plant

Solanum lycopersicum, commonly known as the tomato, is a cornerstone high-value crop for regenerative agriculture systems, offering significant revenue potential per acre and a relatively short production cycle. With many varieties reaching maturity in 55-85 days from transplant, tomatoes lend themselves exceptionally well to succession planting, allowing farmers to provide a continuous harvest from early summer through autumn. This consistent yield stream is highly attractive to direct-to-consumer markets, including farmers' markets and Community Supported Agriculture (CSA) programs, as well as specialty wholesale channels seeking premium produce. The ability to cultivate diverse tomato types, from heirloom slicing tomatoes to cherry varieties, further enhances market appeal and allows for differentiation within farm income streams, making it a vital component of a diversified and resilient farm economy. Quantitatively, yields can range from 15,000-25,000 lbs/acre (16,800-28,000 kg/ha) depending on variety and management.

Integrating tomatoes into a regenerative system offers numerous benefits beyond direct market sales. As a relatively heavy feeder, tomatoes respond well to the improved soil structure and nutrient cycling facilitated by well-managed cover crops and compost applications. Their extensive root systems, typically reaching 18-36 inches (45-90 cm) or even 1-3 feet (0.3-1 meter) in well-tilled soils, help to break up soil compaction, improve aeration, enhance water infiltration, and scavenge nutrients from deeper soil profiles, making them available to subsequent crops. Furthermore, the dense foliage of established tomato plants can offer some degree of weed suppression, reducing the need for mechanical or chemical weed control. Companion planting with basil, marigolds, or borage can enhance pest deterrence and attract beneficial insects, further supporting a healthy agroecosystem.

Quantitatively, the ecosystem services provided by a well-managed tomato crop can be substantial. While not nitrogen fixers, their demand for nutrients can be met through the decomposition of preceding cover crops like vetch or clover, or through the application of compost and aged manure, thereby reducing reliance on synthetic fertilizers. Research indicates that healthy soil ecosystems, fostered by regenerative practices, can support a greater diversity of beneficial insects, including pollinators like bees and hoverflies, which are crucial for fruit set in tomatoes. Improved soil organic matter from cover crop residues and reduced tillage associated with tomato production enhances water infiltration and retention, mitigating both drought stress and runoff. The presence of tomato plants can foster a more biodiverse farm landscape; their flowers attract a variety of beneficial insects, contributing to a more resilient agroecosystem.

Tomatoes have demonstrated success across a wide range of regional farming systems. In the humid subtropical climates of the southeastern United States (USDA Zones 7-9), they are a staple crop for many small farms, often grown in rotation with corn and beans, where growers employ raised beds and drip irrigation to manage soil moisture and reduce disease pressure. In Mediterranean climates like those found in parts of Italy and Spain (Köppen Csa), they are a primary crop, benefiting from long, warm summers and often grown with drip irrigation to conserve water. In cooler temperate regions with shorter growing seasons (USDA Zones 5-6), greenhouse or high-tunnel production extends the season, while farmers in Australia's temperate zones (Australian Zones 2-3) utilize them in diverse horticultural rotations, often following cereal crops. In Brazil's tropical and subtropical zones (Köppen Cwa/Cfa), tomatoes can be grown year-round in suitable microclimates or as a seasonal crop, often intercropped with shade-tolerant species or integrated into agroforestry systems, benefiting from partial shade and improved soil structure. In the corn and soybean belt of the Midwestern United States (USDA Zones 4-6), tomatoes are often grown in rotation after a winter-killed cover crop like Austrian winter pea, providing a high-value cash crop. In the UK's temperate climate (RHS H5-H7), early varieties are often grown in polytunnels or greenhouses to extend the season. In Australia's diverse climate, from the cooler southern regions (Australian Zones 2-3) to the warmer north (Australian Zones 1-2), tomatoes are integrated into horticultural rotations, often following grain crops. In South America, tomatoes are frequently found in smaller-scale, diversified farms, contributing significantly to household food security and local market sales.

How to Integrate This Plant

Practical guidance for regenerative systems

Establishing a successful tomato crop begins with careful seed starting or transplanting. For optimal results, seeds are typically started indoors 6-8 weeks before the last expected frost, sown at a depth of 0.25 inches (0.6 cm) in a well-draining seed-starting mix. For direct sowing, seeds are typically planted after all danger of frost has passed, at a depth of 0.25-0.5 inches (0.6-1.3 cm). Once seedlings have developed 2-3 sets of true leaves and the danger of frost has passed, they are transplanted into the field. Spacing for determinate varieties is generally 18-24 inches (45-60 cm) apart in rows spaced 3-4 feet (0.9-1.2 meters) apart, while indeterminate varieties may require wider spacing of 24-36 inches (60-90 cm) to accommodate their larger growth habit and trellising needs, with row spacing of 3-5 feet (0.9-1.5 m). In many regions, this translates to planting transplants in April or May in the Northern Hemisphere and October or November in the Southern Hemisphere. For example, farmers in USDA Zone 6 might start seeds indoors in early March and transplant outdoors in mid-May, aiming for a harvest starting in July. Planting depth is critical; seedlings should be planted deep enough so that the soil line is at the lowest set of leaves, as tomatoes can root along the buried stem, leading to a stronger root system.

Management practices are key to maximizing tomato yield and quality in a regenerative system. Tomatoes require consistent moisture, with approximately 1-1.5 inches (2.5-3.8 cm) of water per week, ideally delivered through drip irrigation to minimize foliar diseases. Fertility is best managed through the incorporation of well-composted organic matter and nutrient-rich cover crop residues prior to planting. While tomatoes are moderate to heavy feeders, their nutrient needs can be significantly met through biological inputs, reducing reliance on synthetic fertilizers. The need for synthetic NPK inputs can often be reduced by 40-60% through robust soil building practices. Side-dressing with compost tea or fish emulsion can be applied during the growing season if nutrient deficiencies are observed. Growth from transplant to harvest typically takes 55-85 days, depending on the variety, with plants reaching heights of 2-6 feet (0.6-1.8 meters) or more when trellised.

Pest and disease management should prioritize biological controls, such as attracting beneficial insects with flowering plants, using disease-resistant varieties, and maintaining proper plant spacing for air circulation. Companion planting with basil, marigolds, or borage can enhance pest deterrence and attract beneficial insects. Biological sprays containing beneficial microbes or insecticidal soaps can be used as a last resort. Crop rotation intervals of at least 3-4 years are crucial to prevent the buildup of soil-borne diseases; avoid planting tomatoes or other Solanaceous crops in the same spot for at least 3-4 years.

The production cycle for tomatoes in regenerative systems is optimized for continuous harvest and soil health. In temperate regions like USDA Zones 5-7, succession planting every 2-3 weeks from early May through mid-July ensures a continuous harvest from July through October. For continuous harvest, succession planting of transplants every 2-3 weeks from late April through mid-July (Northern Hemisphere) or October through January (Southern Hemisphere) can provide a harvest window of 16-20 weeks. This intensive production cycle draws nutrients from the soil, making it essential to follow tomatoes with a soil-building cover crop. A winter cover crop mix of cereal rye and hairy vetch, or other suitable mixes like cereal rye and vetch, planted within two weeks of the final harvest will protect the soil from erosion, suppress weeds, and fix atmospheric nitrogen, preparing the soil for the next cropping cycle. Prior to planting tomatoes, consider planting a nitrogen-fixing cover crop like clover or vetch, or a biomass-producing crop like oats, to build soil organic matter and fertility. This rotation strategy, combined with minimal tillage and the addition of organic matter, builds soil structure and fertility over time, reducing reliance on external inputs. Following the final harvest, it is crucial to manage crop residues to rebuild soil health. Removing diseased plant material and incorporating healthy residues into the soil within 2 weeks of harvest, followed by a winter cover crop mix, will protect the soil from erosion, suppress weeds, and add organic matter and nitrogen.
