Recommendations for Harvesting Alfalfa in October October 3, 2017

Alfalfa's growing season is usually over by mid-October, but this year many fields received late season rain that's contributing to a substantial, high quality alfalfa crop. Here are some recommendations for a successful harvest when drying times are apt to be slow.

Stalk Rot Diseases in Nebraska Corn Fields September 22, 2017

Stalk rots can be found in corn across Nebraska. This story addresses the risk factors and how to scout for stalk rots, assess stalk strength, and determine extent of damage in a field. Fields with high levels of stalk rot should be given priority at harvest to reduce yield losses due to lodging.

ISU Studies on Rate of Soybean and Corn Dry Down in the Field September 21, 2017

How fast do soybeans and corn dry down in the field? That's the question Iowa State University researchers examined in studies conducted near Ames over the last three years in corn and soybean fields. These briefs share highlights from what they found and can be useful in assessing your fields.

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.

Adjusting the combine feeder house chain with green soybeans can help optimize harvest.

Equipment Adjustments for Harvesting Soybeans at 13%-15% Moisture September 15, 2017

When harvesting higher moisture soybeans, adjustments to your combine and your practices can help minimize challenges in the field, making it easier to achieve a recommended average soil moisture level of 13%.

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.
