Sidedress Phosphorus + MicroEssentials

 
Keep nutrients in the Right Place, where crops can use them.
 
 
A soil test showed a relatively low phosphorus level, so we selected a demonstration of Mosaic’s Micro-Essentials (MESZ) applied as a side-dress (plant nutrients placed on or in the soil near the roots of a growing crop) treatment to provide an additional boost in available phosphorus.
 
 
MESZ allows uniform nutrient distribution and provides essential nutrients crops need in one granule. It has two forms of sulfur for season-long nutrition.
 
It was side-dressed at two rates with a control plot where it was not applied.

Operation
 
Herb and Aaron Steffen, of Cropsey, Ill., operate a 900 acre grain farm in southern Livingston and northern Mclean counties. Two thirds of the acreage is devoted to continuous corn with one third in a corn/soybean rotation.
 
Minimum tillage practices are used to leave at least 30% residue on the soil surface.
 
Nitrogen is applied after the corn has emerged, and when the plant needs are the greatest, to minimize loss of nitrogen through leaching.
 
Currently there are three test plots on the Steffen farm.
