Plant Analysis as a Management Tool for Corn and Soybean Fields


Start Date: 2012

Principal Investigator: Daniel Kaiser

Organization: University of Minnesota, Department of Soil, Water and Climate

Status: Complete

Background Information:

The research completed to create this report aimed to validate using plant tissue analysis in the evaluation of potential hidden nutrient deficiency problems within fields. These researchers questioned whether plant tissue and the current industry norms are relevant for today’s hybrids and varieties.


The study proposed further investigation into three areas of plant analysis: 1) How variable are nutrient analyses for different corn hybrids grown under the same conditions? 2) Can grid sampling with plant analysis aid in the assessment of potential nutrient deficiencies for corn and soybeans? 3) And how do current values from mid-season tests compare to established industry norms?
