Fertilizer-nitrogen Injury to Corn

May 17, 2023

Nebraska Extension recommendations on minimizing crop injury from anhydrous ammonia applications.

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.

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.

Nebraska Soil Health School Offers Expert Insights to Producers, Ag Professionals Statewide

March 13, 2023

Following a successful premiere of the new Nebraska Soil Health School, the second installment will be June 27-28 at the West Central Research, Extension and Education Center in North Platte, Nebraska.

Evaluation of Diverse Cover Crops Across Nebraska: Findings from Spring-planted Cover Crops in 2022

February 23, 2023

Results from 2022 variety trial research conducted on numerous cover crop species at five UNL research stations across Nebraska.

Cropland Reference Ecological Unit — A Land Classification Unit for Comparative Soil Studies

September 29, 2022

UNL researchers have developed the Cropland Reference Ecological Unit and Soil Health Gap concept to offer a method of describing the true soil health potential of land.

Another Dry Year: What to Know About Leftover Nitrogen in Soil Following Dry Conditions

September 28, 2022

In irrigated or dryland areas with normal production, management practices may continue as normal, but for dryland areas with drastic yield reductions, there is potential for nitrogen fertilizer adjustment for the 2023 crop.

NRCS-UNL Collaborative Research on the Soil Health Gap Analysis in Nebraska

April 12, 2022

The Soil Health Gap concept can assist producers in estimating differences of soil health under varying management practices that may have accumulated since cultivation began.
