Application of Manure to Double Crop Soybeans (Jun 21, 2017)

In recent years, there has been more interest from livestock producers in applying manure to newly planted soybeans to provide moisture to help get the crop emerged. Both swine and dairy manure can be used to add moisture to newly planted soybeans. It’s important that the soybeans were properly covered with soil when planted to keep a barrier between the salt and nitrogen in the manure and the germinating soybean seed.

It’s also important that livestock producers know their soil phosphorus levels, and the phosphorus in the manure being applied. An acre-inch of water is 27,154 gallons. The application of 10,000 gallons per acre of dairy manure would be about 0.37 inches of moisture. The application of 7,000 gallons of swine manure would be about 0.26 inches of moisture. While the incorporation of livestock manure is strongly encouraged whenever possible. 

If manure is incorporated prior to planting double crop soybeans be sure the manure salt and nitrogen is not placed in the planting zone. Placing the manure in contact with germinating seeds can result in severe emergence problems.
