Farm grain bins
Figure 1. The various sized bins on this farm allow for storing different moisture contents. Wetter, more dense grain works well in the smaller bins so that more airflow per bushel can be delivered. Drier grains where aeration is the primary need store well in the larger bins. If the grain is wetter, drying grain in layers can help increase airflow per bushel. (Photo by Paul Jasa)

Natural Air Drying of Binned Soybeans September 20, 2017

If soybeans were harvested above 13% moisture, natural air drying can be used to reduce moisture to 13% for longer term storage. How long that drying takes will vary with several factors. This guide can help you estimate the length of drying for your soybean moisture, aeration system, relative humidity and temperature.

Plan Harvest to Deliver Soybeans at the Optimum Moisture September 14, 2017

Most soybeans are harvested and delivered directly to an elevator instead of being placed in on-farm storage. Soybeans delivered below or above 13% moisture—the elevator standard—lose potential profit. The economics illustrated here show how harvest timing can affect potential income.
