Top-Dress Alfalfa This Fall to Boost Yields and Cut Costs
Middle West Soil Improvement Committee urges fall phosphate and potash fertilization to store nutrients in alfalfa roots, boosting winter hardiness and next spring growth. Soil tests guide fertilizer ratios, with recommendations of 300 to 500 pounds per acre of blends like 0-20-10 or 0-10-30, boron added where needed.
Fall Fertilizer Boosts Spring Yields and Labor Savings
The Middle West Soil Improvement Committee urges fall fertilizing to save time and labor in spring planting. Heavy equipment can work fields in fall when ground is firm, reducing soil packing and storage issues. Top-dressing alfalfa in fall reduces winter kill and aids early growth, while risk of nitrogen loss varies with soil type and winter rain.
