Many farmers are well-versed in the 4Rs of nutrient stewardship: apply the right source at the right rate, at the right time, in the right place. Following this framework ensures crops use nutrients efficiently and effectively, helping no-tillers maximize their fertilizer budget.
Minnesota farmers Nancy and Jerry Ackermann credit strip-till, split nitrogen applications and cover crops for helping them reach 200-bushel corn yields on 140 pounds of nitrogen.
Nancy and Jerry Ackermann have been strip-tilling corn and no-tilling soybeans and alfalfa on their 1,200-acre farm in southwest Minnesota for 15 years. Coming from conventional tillage practices, the transition began on a small 50-acre test plot.
University of Illinois Extension says that the lower price of corn mean decisions about N management need to be carefully, with an eye towards maximizing the return to this input.
Planning your crop’s fertility begins with soil testing, followed by planning your fertilizer application, followed by summer tissue testing. Some nutrients will go on in the fall, others in the spring and the rest in the summer, depending on you and your agronomist’s approach to nutrient management.
Seeing the potential for more than just erosion control, Ohio growers Bret and Gene Margraf overhauled their no-till system by adding wheat and cover crops, variable-rate seeding and fertility and split-nitrogen applications.
