Crop Management

Crop management hinges on the availability of water. For example, optimal plant populations will vary depending on the quantity of water available during the growing season.

The gift that keeps giving: manure important resource for crop producers

Alfalfa in Rotation with Annual Crops Reduces Nitrate Leaching Potential and Increases Soil Organic Carbon Sequestration

As it aggressively scavenges nitrogen in the soil, alfalfa can greatly reduce nitrate contamination of groundwater with no negative implications for future crops if planted in rotations.
This UNL research study provides insights on the rotation of annual crops with alfalfa as a highly effective means of reducing nitrate-nitrogen contamination in groundwater.

Understanding Soil Residual Nitrogen and its Dollar Value for Next Crop

For producers planting corn-on-corn this growing season, Nebraska Extension encourages taking soil samples to determine accurate nitrate levels and adjusting N application rates accordingly, as there may be considerable amounts of residual nitrogen left from the previous corn crop.
For producers planning corn-on-corn this growing season, there may be a substantial opportunity to reduce nitrogen fertilizer applications, as drought and reduced yields likely left higher-than-normal residual N in many fields.
