Each harvest comes with a degree of soil nutrient removal, depending on the crop and yield. Consider a fall fertilizer application to maintain nutrients in the soil after harvest and prepare fields for the 2021 growing season. Read on to learn how interpreting soil test results and strategic application timing can set you up for success next year.
Evaluate the yield response of corn to Aspire®, MOP and MOP + Granular B blend in fall vs. spring applications.
Evaluate the yield response of MAP (11-52-0) + Aspire® (0-0-58-0.5B) and MicroEssentials® SZ® (12-40-0-10S-1Zn) + Aspire® applied in the fall and spring compared to MAP alone.
Required by all plant life, potassium (K) plays a major role in photosynthesis, breakdown of carbohydrates, protein synthesis and disease resistance. Most importantly, it can activate at least 80 enzymes that regulate the rates of major plant growth reactions. The aforementioned activities should all occur in-season, but what can be done to ensure a crop has the proper levels of K to carry out these functions? And should the applications be made in the fall or spring?
Risks associated with fall nitrogen (N) applications fit into four categories: logistical, agronomic, environmental and economic, the last of which currently ties very closely to the others and will be discussed in conjunction with them.
For Luke Lantz, a farmer from Lake Crystal, Minnesota, fall fertilization plans are not a one-size-fits-all program.
