Soybean Response to High Fertility Management

Objective

  • Evaluate soybean yield response to a high soil fertility system in the Red River Valley of the North.

Study Description

Plot Layout:    On-farm, full field
Locations:   Elbow Lake, MN
Mahnomen, MN
Pioneer® Brand Variety:    90Y70(RR)
Soil Fertility:   High Fertility Program
           12 lbs/acre Nitrogen
           40 lbs/acre Phosphorous
           60 lbs/acre Potassium
           10 lbs/acre Sulfur
    No Additional Fertilizer
  • Fertilizer treatments were applied immediately after planting.

Results

  • Soybean yields were similar between high fertility and normal fertility programs at both locations.
  • Results presented here are for year 1 of a multiyear study.

PIONEER® brand products are provided subject to the terms and conditions of purchase which are part of the labeling and purchase documents. 2012 data are based on average of all comparisons made in 2 locations through November 21, 2012. Multiyear and multilocation is a better predictor of future performance. Do not use these or any other data from a limited number of trials as a significant factor in product selection. Product responses are variable and subject to a variety of environmental, disease and pest pressures. Individual results may vary.

Glyphosate Tolerant    R - Contains the Glyphosate Tolerant trait. Always follow grain marketing, stewardship practices and pesticide label directions. Varieties with the Glyphosate Tolerant trait (including those designated by the letter “R” in the product number) contain genes that confer tolerance to glyphosate herbicides. Glyphosate herbicides will kill crops that are not tolerant to glyphosate.
