Creating Management Zones Using Electrical Conductivity

The first step to practicing zone management is to identify the variations that control yield. There are various methods for characterizing soil variations within a field, and among them, electrical conductivity measurement is one of the most-reliable.

Forecasted Cold Temperatures Can Be Used To Cool Down Stored Grain

If temperatures are forecasted as being well below freezing, it would probably be a good time to start thinking about cooling stored grain. Cooling grain reduces the activity of stored grain insect pests and suppresses any mold growth that may otherwise occur.

Pollinators Are Active in Sunflower

While scouting sunflowers, it’s hard to not notice the constant buzzing present in the field, which is produced by numerous species of bees. While sunflower varieties grown in the United States were bred for self-fertility, there is evidence that both honey bees and native wild bees can improve pollination.

Floodwater: Road Crossing Hazards

During flooding, and when driving in the countryside we oftentimes encounter a creek or stream running on top of the road. Be aware that a course of water running over the road can turn into a very dangerous, even life-threatening situation if you attempt to cross it with your vehicle.

Common Stalk Borer Activity Estimate: May 13, 2021

The upcoming weather forecast looks warmer than the last few weeks, and that means we will begin to accumulate degree days for the common stalk borer at an increased rate.

Common Stalk Borer Activity Estimate: April 29, 2021

As temperatures continue to warm up, degree days are beginning to accumulate a little faster for common stalk borers. Most of South Dakota is still between conditions approaching egg hatch and egg hatch occurring.

Common Stalk Borer Activity Update: May 16, 2019

The hatching and movement of common stalk borer caterpillars can be estimated by using degree days with a developmental threshold of 41 degrees Fahrenheit. Common stalk borer eggs typically begin to hatch at 575 degree days.
