Estimating a Fair Value for Standing Forage

July 29, 2020

Several things need to be considered when deciding what value to place on standing forage. Forage prices reflect current inventories, demand, expected current season production and associated yield risk, and quality characteristics.

Reducing Nitrate Concerns When Grazing Forage Cover Crops

July 22, 2020

Nitrate toxicity can be a concern when planting cover crops for forage in hail-damaged crop fields. With proper management of haying and grazing, the risk can be reduced.

Cover Crop Considerations Following Late-Season Hail

August 29, 2019

Late-season hail has impacted fields across Nebraska. Growers may want to consider the value of cover crops for weed management, excess nitrogen uptake, and forage options.

The Value of Grazed Corn Residue for Crop and Cattle Producers

July 31, 2019

It's estimated that a 10% increase in grazing utilization of corn residue could add $6.4 million to the bottom line of crop producers in Nebraska.

Cover Crop Grazing: Impacts on Soils and Crop Yields

January 22, 2019

Results from a three-year study in rainfed and irrigated no-till cropping systems in Nebraska suggest that moderate cattle grazing of cover crops may not negatively impact soil properties and crop production.

Native Warm-Season Grass Management and Planting Decisions for Alternative Forages

January 9, 2019

One of the most important drivers of productivity and cost effectiveness of annual forages is planting date. Having realistic planting date expectations is one key to proper species selection.
