Proper winter soil care ensures a healthier, more productive foundation for spring planting.

Assessing Soil Health Before Winter

 Importance of Soil Testing

Before you begin winter preparations, understanding the current state of your soil is essential. Soil testing provides valuable insights into its pH, fertility, and the presence of contaminants such as heavy metals. These insights guide your approach to soil amendments and fertility management.

Our lab offers a range of services, including agricultural soil testing, garden soil analysis, and heavy metal testing. By partnering with us, you can identify specific issues and develop targeted solutions to improve your soil’s health.

 Common Soil Issues Found During Testing

Some common issues that arise during soil testing include:

  • Nutrient deficiencies (e.g., nitrogen, potassium, or phosphorus)
  • Imbalanced pH levels, which can hinder nutrient absorption
  • Contaminants like heavy metals that may affect crop safety

By addressing these issues during winter, you can ensure optimal growing conditions come spring.

 Tools for Soil Sampling

Using the right tools ensures accurate soil sampling. Tools such as soil sample probes and soil testers are essential for collecting representative samples. Our lab provides guidelines and support to help clients worldwide collect and submit high-quality samples for analysis.

Steps to Optimize Soil for Winter

Fertilizer and Amendments

Winter is an ideal time to apply fertilizers and amendments tailored to your soil’s needs. Based on your soil test results, you can:

  • Add lime to correct soil acidity.
  • Apply organic matter like compost to boost nutrient content and improve soil structure.
  • Use phosphorus and potassium fertilizers for long-term nutrient availability.

Properly balanced fertilizers enhance soil fertility and prepare your fields, gardens, or lawns for a thriving growing season.

Cover Crops and Mulching

Planting cover crops such as clover, rye, or vetch protects soil during the colder months. These crops reduce erosion, fix nitrogen, and improve organic matter when tilled into the soil in spring. Similarly, applying mulch insulates the soil, reduces compaction, and conserves moisture.

For those unfamiliar with cover crops, our agricultural consulting services can recommend the best options based on your soil type and goals.

Soil Structure Management

Soil compaction can worsen over winter due to heavy precipitation and freezing conditions. To combat this:

  • Avoid heavy machinery use when the ground is wet or frozen.
  • Incorporate organic amendments to improve aeration.
  • Consider aerating compacted soil areas before winter begins.

Our team can analyze soil compaction issues and suggest customized solutions for your unique environment.

Understanding the True Value Behind the Price Tag
By Joe Pedroza April 30, 2025
As summer sets in across much of the country, crops enter one of the most demanding phases of their life cycle. With increased heat, active fruiting, and water stress, nutrient uptake becomes more unpredictable. Even the most well-fertilized soils may fall short in delivering the right nutrients at the right time. That’s where mid-season plant tissue testing becomes an invaluable tool. Why Soil Tests Alone Aren’t Enough Soil tests provide a vital baseline before planting, helping you understand what's available in the root zone. But as the season progresses, multiple factors can interfere with nutrient uptake: Heat stress and limited moisture reduce nutrient movement in soil, making it harder for roots to access nutrients even when they're present. Soil pH shifts —common as microbial activity changes—can lock up nutrients like phosphorus, zinc, or iron, rendering them unavailable to plants. Plant demand changes rapidly during flowering and fruiting, meaning nutrient requirements evolve faster than soil reserves or slow-release fertilizers can respond. A mid-season tissue test reveals what the plant is actually absorbing, not just what’s in the soil. What Tissue Testing Tells You A tissue test provides a real-time snapshot of the plant’s nutritional status. It helps identify: Early signs of nutrient deficiencies , often before symptoms show up visually. This allows for preventative correction, rather than trying to fix a visible problem too late in the season. Imbalances between key nutrients , such as excess nitrogen suppressing calcium uptake, or low magnesium reducing potassium efficiency. Uptake issues caused by stress , poor irrigation practices, or compacted root zones—especially important in summer when evapotranspiration is high and root efficiency is lower. Tissue testing gives you the insight needed to make targeted nutritional corrections , optimizing fruit set, size, and quality. When and How to Tissue Test For most fruiting crops, ideal sampling windows include: Just before flowering , when nutrient demand is about to spike. Early fruit development , to support strong cell division and prevent blossom-end disorders. Mid-season (peak fruit load) , when nutrient draw is at its highest and deficiencies are most likely to develop. Select healthy, recently matured leaves from a representative section of the field. Avoid leaves with obvious damage, disease, or pest activity. Consistency in sampling location and leaf age is critical for accurate comparisons over time. At TPS Lab, we provide detailed sampling instructions and fast turnaround times, so you can act before yield is compromised. Common Summer Deficiencies to Watch For Even in fertilized fields, these nutrients often fall short under summer stress: Potassium (K): Crucial for water regulation, sugar transport, and fruit development. Deficiencies can cause uneven ripening, poor flavor, and lower yields. Calcium (Ca): Required for cell wall strength and fruit quality. Limited uptake often causes blossom end rot in tomatoes and peppers or tip burn in leafy greens. Magnesium (Mg): A central component of chlorophyll. Magnesium deficiency can lead to interveinal yellowing and poor photosynthesis, especially under intense sunlight. Micronutrients (Boron, Manganese, Zinc): These trace elements play vital roles in pollination, enzyme function, and hormone regulation. Even minor deficiencies can lead to poor fruit set or malformed growth. How to Act on Results Once your results are in, use them to tailor your in-season fertility program. Depending on the crop and severity, this might involve: Adjusting fertigation blends to include more soluble potassium or micronutrients based on test results. Applying foliar sprays for immediate correction, especially for mobile nutrients or in cases where soil uptake is impaired. Incorporating amino acid-based fertilizers or biostimulants to enhance nutrient absorption, increase stress tolerance, and promote balanced growth without risking burn or over-fertilization. TPS Lab consultants can help interpret your report and recommend specific products or strategies—whether that includes our own solutions like Nitro P9 or CSL+ , or broader categories suited to your operation.
