Manure Improves Soil Health and Provides Yield Stability and Reliability

March 17, 2023

UNL researchers share their results after 77 years of applying manure to soil at the Knorr-Holden plot, the oldest experimental irrigated corn plot in North America.

Manure application — The value of manure depends upon several factors that must be assessed, including its type, how and where it's applied, the amount of nutrients needed in the field for the next crop and the cost of fertilizer.

Calculating the Value of Nutrients in Manure

March 16, 2023

Nebraska Extension Animal Manure Management Educator Leslie Johnson walks through the steps of calculating manure value.

Tractor spraying soil — 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.

Understanding Soil Residual Nitrogen and its Dollar Value for Next Crop

March 14, 2023

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.
