Plant Tissue Sampling: In-season Fertility Management
Plant tissue sampling is a great tool in our agronomic tool box and has various impacts in both a preventative and a reactive decision-making process. Tissue sampling provides insight to potential deficiencies, diagnosing visual symptomology, and validating fertility programs. Our Verify® plant tissue sampling tool is an excellent way to not only help monitor nutrient demands and needs locally but also observe crop trends nationally.
Coupled with aerial imagery, tissue sampling has the opportunity to detect plant nutrient deficiencies before physical signs are present. Sample results provide the information needed to select the proper amount of nutrients and the product needed. Sampling should take place 7-10 days prior to any critical growth stage and/or before a pass is made across the field. Proper product selection, placement, and timing follow the guidelines of the 4R's of nutrient management.
