Brief Project Summary:

The project will look at iron-deficiency chlorosis (IDC) response of varieties with and without tile drainage. Also fertilizing soybeans with nitrogen is included in the proposal. The research will address issues of interactions between soybean varieties with and without sub-surface drainage as well as the effect of nitrogen, LCO, and micro nutrients on plant growth and yield. Producers are interested in knowing if tile drainage is a good investment and results of this research will contribute to increased understanding of the effects of tile on the yields of soybean.

Information And Results
Project Deliverables

• Increased soybean yields in a wet season
• Determine economics of nitrogen applications

Final Project Results

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.
