A diverse 14-way mix was planted into wheat stubble immediately after harvest to keep living roots in the field.  The cover crop is using sunlight and carbon dioxide to put energy and carbon into the soil to feed the soil biology.

Cover Crops for Soil Health in Storm-damaged Fields July 13, 2018

Fields that were hailed, flooded, windblown, or where planting was prevented this season can benefit from the many soil services provided by cover crops. In addition a growing cover crop can help reduce erosion from water and wind and may help protect soil moisture levels.

Planting
Figure 1. Planting down the old row and leaving the residue attached can help reduce the potential for wind erosion. Residue movers should not be used as they detach residue, allowing it to be moved by wind or water.

Practices to Reduce Wind Erosion May 11, 2018

Keeping your soil covered with growing cover crops or crop residue are two of the best ways to help protect it from wind erosion. Both practices will help to keep the wind off the soil surface and reduce soil moisture evaporation, providing a moister soil that's less apt to move.

Building Resilient Soil Systems using Residue, No-till, and Cover Crops March 29, 2018

Crop residue, cover crops, and no-till farming practices can provide a positive buffering effect to changes in climate and extreme weather events. Together they can help keep more water and soil on-farm and contribute to improved soil health.

To avoid compacting more of the field, the grain cart should run down the same row middles as the combine. An auger extension may be needed on the combine to get the wheel tracks to line up. The wheel spacing on the combine, tractor, and grain cart should be adjusted to all run between the rows.

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.

Q&A - Any Tips for Setting my Drill for Seeding Wheat? September 1, 2017

Q: Last year I didn't get good seed-to-soil contact with my wheat seeder and my stands were uneven. What should I do differently? Proper seed depth and weight on the drill are among the factors to check.
