Fertilizer was a painful input for most no-tillers in 2008. Growing world demand (up 14% — a growth equal to the entire U.S. market, according to The Fertilizer Institute), high production costs, increased transportation expense and a faltering U.S. dollar all contributed to record-high prices for major nutrients.
Fred Below looks at pushing up corn yields in a much different way than many researchers. The crop physiologist at the University of Illinois has determined that 7 critical items have the most impact on corn yields.
With skyrocketing input prices like seed and fertilizer, it pays to measure your production and more closely manage your inputs. One of my favorite management slogans is, “Measure to manage.” Without measuring your inputs and yields, it’s really hard to manage to the highest level of profit.
If you're not measuring the nutrient needs of your soils, you may be throwing tons of money away and hurting your soil structure — even if you’re no-tilling.
Besides looking at new traits, plant breeders are paying close attention to each new corn hybrid’s reaction to various production practices. These include a hybrid’s performance with post-emergence herbicides, foliar fungicides, different seeding rates, various planting dates, continuous corn and nitrogen usage.
Most no-tillers can recall a time (or incident) when the “light went on” — when no-till became an obvious option. For me, that happened in 1986 during a dry spring.
According to Paul Jasa, Extension agricultural engineer at the University of Nebraska, no-tillers can minimize soil disturbance with existing application equipment. The key is setting the machine correctly and having the right coulters and shanks in place to do the job.
