According to study from Department of Natural Resources researchers, irrigation pivots stained with rust may indicate the absence of nitrate in the groundwater supplying the pivots. This information can potentially be used to help screen for areas for the potential absence of nitrate and, in an ideal world, could indicate areas at higher- or lower-risk for nitrate contamination before it becomes a problem.

In 2023, the Nebraska Legislature passed LB1014.  This bill took 4 million dollars from the American Rescue Plan Act and allocated it to treating nitrate issues in Nebraska.  1.2 million dollars of that has been dedicated to a Reverse Osmosis Rebate Program that is directed at private well owners. The general idea of the program is that any individual private drinking water well owner can test their water AND if the nitrate concentration comes back above 10 ppm, they might be eligible for UP TO $4,000 support to get a reverse osmosis system to treat their nitrate.

Nebraska farmers and agronomists are set to present results of their 2022 on-farm research studies on cover crops, variable rate seeding, starter fertilizer, biological products, seed treatments, variable rate nitrogen management and more.

Zoom training sessions will focus on pesticides for corn and soybean on March 8 and April 4, and for pastures on March 21.

A new Nebraska Extension NebGuide clarifies the concept of consumptive use of water with regard to irrigated crop production and provides guidelines for determining the efficiency of new irrigation technology.

Nebraska NRCS has announced ACT Now Signup 2 for initiatives and EQIP programs. An ACT Now signup process will be utilized for the Bazile, Big Sandy and Turkey Creek NWQIs and EQIP CPAs, DIAs, and CEMAs. Applications that may have been received for these initiatives after the November 18, 2022 EQIP application cutoff but prior to the December 19,2022 Signup 2 announcement, are eligible as well.

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.
