NutriSolutions 360® System

Manage macro- and micronutrients to promote high forage production.

  • Soil test to ensure that soil pH levels are on target. Alfalfa requires a neutral soil pH for high production. Review the test to ensure the necessary macro- and micronutrients are present to fuel alfalfa growth.
  • Test soil to take inventory of the nutrients that are available and those that are lacking. – pH 6.8 to 7.2 (lime alfalfa ground one to two years before seeding) – Potassium (potash or K) soil test = 300 lbs or 150 ppm – Phosphorus (P) soil test = 50 lbs or 25 ppm

NutriSolutions® Tissue Testing

NutriSolutions® tissue testing should be timed with your crop protection and plant nutrient applications schedule.
  1. In the spring after alfalfa plants break dormancy and reach approximately 6 inches in height, apply Headline® fungicide and Ascend® plant growth regulators at recommended rates.
  2. Prior to the first cutting, take a NutriSolutions® tissue sample of the top 4 to 5 inches of growth.
  3. Harvest the first alfalfa crop.
  4. Review the NutriSolutions® results and apply the recommended micronutrients at the suggested rates when plants reach approximately 6 inches in height. We also recommend applying Ascend® PGR if the moisture available can support yield potential. The Headline® fungicide application may be necessary to help control foliar leaf diseases, Anthracnose and mildew to protect against yield and quality loss.
  5. Repeat steps 2, 3 and 4 for consecutive cuttings. Always monitor fields closely in season for plant and leaf diseases, and insect pressure.

Plant Nutrients

WinField® plant nutrition products help jump-start plant growth and bolster plant health. Contact your local WinField representative or visit for more information. Always read and follow label directions.

Plant nutrient products accelerate leaf, stem and root growth for strong, healthy plants. It can be used as a foliar application or as a seed treatment promoting plant health and growth.

Plant Tissue Nutrient Requirements for Alfalfa Compared to Corn              

              Ideal nutrient levels for alfalfa
These are the ideal nutrient levels to maximize alfalfa growth for high quality and high yield potential. The ideal nutrient levels for each crop are different. Meeting crop needs may require fine-tuning your nutrient applications for each crop. The payoff is additional high-quality, “nutrient dense” forage.

How to Take a Nutrisolutions® Alfalfa Plant Tissue Test

Collect the leaves and stems of 30 to 35 plants. Before cutting: Sample the top 4 to 5 inches of growth. A soil sample should be collected at the same time as the plant tissue test. Do not mix soil and tissue samples.
