Part 2 of a six-part series that will cover the major rivers and their respective drainages found in Nebraska, with some geography and history about Nebraska’s rivers.

The Soil Health Nexus is excited to debut two new resources on the Soil Health Toolbox! Two Soil Health Nexus members, Francisco Arriaga, Associate Professor and Extension Specialist at the University of Wisconsin-Madison, and Anna Cates, Assistant Professor and State Soil Health Specialist at the University of Minnesota, recently published a long-awaited whitepaper exploring the connection between soil health and water quality.

This year’s 4Rs Field Day will focus on up-to-date research information and demonstrations on all three major crop nutrients: nitrogen, phosphorus and potassium.

Industry experts shared snowpack/snowmelt runoff estimates for the upper North Platte River basin, updates on UNL irrigation management research and progress on replacing the Goshen/Gering-Ft Laramie tunnels that collapsed in 2019.

Extension recommendations for calculating the amount of nitrate-nitrogen in irrigation water and optimal timing of applications to reduce the cost of nitrogen inputs in irrigated corn.

This new series by Nebraska Extension Educator Gary Stone highlights the main rivers in Nebraska and their impacts across the Midwest and Northern Plains. Part 1 of a six-part series that will cover the major rivers and their respective drainages found in Nebraska, with some geography and history about Nebraska’s rivers.

This week — Strategies for irrigating alfalfa in early season dry soil conditions, grazing to control abundant weed growth due to drought and forming a drought plan.

There are so many decisions to be made when it comes to vegetable gardening. Selecting the right location, determining what to plant, even how many plants you might need. One topic that might not have crossed your mind is how to make the vegetable garden more water conscious. Conserving water in the vegetable garden may sound more difficult than it really is.

This year's conference will focus on innovative ways to improve water and food security by increasing farmers’ resiliency to a changing landscape.

The 2023 TAPS Competition participants will soon make their first decisions of the growing season — watch for updates in the coming months as participants choose their seed varieties, manage nitrogen applications and irrigation, and more.

Eastern Nebraska tends to have high soil pH, also known as alkaline soil, which can cause problems for some plants, like river birch, pin oak, big-leaf hydrangeas and blueberries to name a few. Alkaline soil changes the availability of certain plant nutrients in the soil, often making them less available, resulting in deficiency symptoms.

When we plant a garden or flower bed, we think about sunlight preferences, color and bloom times most often, but there are other factors to think about including water requirements for the plants. All plants need water to survive, but they differ greatly in how much they need. Some plants are best planted along a pond edge or other very wet location because they like swampy, over irrigated locations. Where other plants require dry, well-drained soil. There are even some great plants used in rain gardens and similar areas that actually do well in both wet locations as well as dry conditions to overcome the changing environment when water collects during rain events and dries out between rains.

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.

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.

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.

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.

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

“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.
