An innovative option makes broadcast crop nutrient applications more available.
Farmers wouldn’t be satisfied with just 20 percent weed control from a herbicide application, but that’s typically the best nutrient availability they can expect from dry phosphate fertilizer applications.
“Under the best soil conditions, only one-fifth of applied phosphorus may be available to the crop throughout the season,” says Steve Carlsen, Levesol and crop enhancement manager, CHS Agronomy. “Availability is even less when soil pH levels are too high or too low or in soils that contain too little organic matter.”
Crops demand nutrition throughout the entire growing period, but most of them can’t utilize those nutrients effectively during early development. A shortage of nutrients can lead to significant yield loss and stunted plant development.
How effectively those nutrients are managed in the spring can affect how the crops look in the fall. Weather and other pest and weed influences can also impact crop growth and development, but good nutrient management is essential as crops reach the final stages of growth. As crops move through the grain fill period in the fall, growers need to keep an eye out for nutrient deficiency symptoms. (more…)
