Final Project Results

The 2016 and 2017 growing seasons did not produce a significant positive response to poultry litter, potassium thiosulfate, foliar micronutrients, or fungicide. In addition, results indicated a soybean intensive management system utilizing prophylactic applications of multiple inputs was not an economic benefit to producers. Data from the 3 site-years of this trial appears to provide continued support for the use of university IPM programs that emphasize both grain yield and profitability. Michigan soybean producers should look to incorporate a management system that utilizes a variety of different techniques (e.g. tissue and soil analysis, crop scouting, prediction models) to minimize and validate input applications to match specific crop needs and maximize profitability rather than applying a combination of inputs as risk insurance.

No single input added generated a significant grain yield increase or positive return on investment

Traditional management on average significantly increased producer return on investment by $213 A-1

Minimal potential for grain yield and economic benefit from intensive soybean management w/o adverse environmental conditions.
