The proposed research project is part of a larger plan that will investigate the yield response of commonly grown crops in North Dakota and Minnesota under tiled and non-tiled conditions. After identification of crop responses to tile drainage further studies will focus on fine tuning crop rotation, fertility management, and crop residue management. This trial is based on previous research on intensive management where the combination of the LCO growth stimulator, micro nutrient mix, and fungicide resulted in higher yields. This research is aimed at helping us to understand if the LCO or micro nutrients are contributing to increased yield. The expected impact of this research...
In 2011, a relatively wet year, a significant difference of 3.9 bushel per acre was detected between the no tile (48.5 bu/a) and tile treatments (52.4 bu/a) with a value of $52.65 (May 2012 average soybean price).
This research indicated that there is an increase in soybean yield during a wet season with tile drainage (2011). The economics of nitrogen application depend on the cost of nitrogen and soybean price. The price of nitrogen fertilizer is a major factor in the profitability analysis. Producers need to consider the economics of applying nitrogen to soybeans based on the fertilizer price and anticipated market prices of the soybean crop.
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
