Crop Production

Nebraska Extension Educator Laura Thompson and Lexington farmer Don Batie discuss research studies conducted by the Nebraska On-Farm Research Network and their impact on farming in Nebraska.

TAPS is expanding its competition in 2023 with a new irrigated popcorn competition, a cover crops option for sprinkler corn, and a new location for the sorghum competition. The expansion also includes a new TAPS competition in Colorado.

“How much is this manure worth?” This is a common question from both livestock farmers who are supplying manure and crop farmers who are utilizing it. To answer this question, it is important to understand the difference between gross value and net value. The gross value of manure reflects the equivalent commercial fertilizer value of the nutrients contained in the manure. The net value considers the impacts of application method, transportation, and cropping system nutrient needs as well as intrinsic values that are much more difficult to put a number on. Therefore, this article will focus on determining the gross value of nutrients in manure.

Cattle manure is a valuable resource for farmers, as it contains an abundance of macro and micronutrients that are essential for plant growth and development. The nutrients present in manure, such as nitrogen (N), phosphorus (P), potassium (K), and other minerals are essential for soil fertility. One of the most significant advantages of using cattle manure as a fertilizer is that it can enhance the soil organic matter (SOM) content. Soil organic matter plays a crucial role in improving soil structure, water-holding capacity, and nutrient availability. Moreover, cattle manure can also increase the changeable fractions of carbon (C) & nitrogen (N) and enhance soil microbial activity, which is crucial for the decomposition and stabilization of soil organic carbon (SOC). The Knorr Holden plot, located at the Panhandle Research, Extension, and Education Center, Scottsbluff, Nebraska presents a unique opportunity for studying the impact of long-term manure (more than 77 years) applications on soil health and crop productivity.

Many farmers and ranchers make inquiries to Nebraska Extension about prevailing rates paid for various kinds of custom farm services. In addition to the regular biennial custom rates survey, the University of Nebraska-Lincoln’s Center for Agricultural Profitability has launched a new survey designed to provide market rate information for the Nebraska livestock industry. Producers and operators that perform and provide custom services for others, or that utilize custom services and pay others, are invited to participate in the survey.

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

The nearly 70 on-farm research studies conducted by Nebraska farmers in 2022 addressed fertility and soil management, cover crops, crop protection, equipment and non-traditional products, including biologicals.

Several areas of Nebraska had a one- to two-category improvement in drought conditions throughout the winter season, which has been the fifth wettest winter on record for the state.

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.

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.
