Fall soil testing can maximize yields
For accurate results, representative samples from a proper depth throughout a grower's fields are necessary. Sampling methods depend on cropping and fertility management practices. Check with your local Pioneer expert for more information on correct sampling methods.
Soil test results can alter a grower's nutrient application rates. For cost-effective application in the fall, Diedrick suggests using a granular, dry fertilizer.
"Dry fertilizers will dissolve and react with the soil similarly to liquid fertilizers," says Diedrick. "Most dry applications can be soluble with little rainfall, and are easier and more economical to handle in large quantities."
However, N application is generally more efficient in the spring. "Fall and winter applications can result in potential losses of significant amounts of nitrogen," says Diedrick.
Whether you decide to apply nutrients in the fall, winter or spring, consistent testing from year to year is one of the best ways to ensure a balance between economic and environmental factors.
