Watershed Planning & Management

Watershed planning and management comprise an approach to protecting water quality and quantity that focuses on the whole watershed. This approach is necessary due to the nature of polluted runoff, which in most watersheds is the biggest contributor to water pollution. Polluted runoff is a caused by a variety of land use activities including development, transportation and agriculture, and may originate anywhere in the watershed. Watershed planning and management involves a number of activities including:

Livestock & Poultry Expansion: Critical Issues for Discussion with Farmers and Communities

There is a growing interest in establishing new livestock and poultry facilities in Nebraska, many of which will involve contractual arrangement with supply chain partners. Our purpose is to inform Extension educators and other farm advisors on those critical issues to be considered in the planning of a new livestock/poultry facility and prepare these advisors for leading farmers successfully through this process.

Nutritional Value for the Landscape

Processing lawn clippings and tree leaves into the lawn provides nutritional value as well as reduces waste. Generally, turf clippings contain 6-7% nitrogen, 0.5 to 1.0% phosphorous and 2-4% potassium; when returned to the lawn, they can account for a fourth of the lawn's fertilizer applications each year.

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.

What is a pesticide?

The public is becoming increasingly concerned about the harmful effects of pesticides on the environment. Protecting water and the environment is a key element of the University of Nebraska-Lincoln Extension Pesticide Safety Education Program (PSEP). It is essential that pesticide applicators understand all aspects of the pesticides they use in order to properly manage them. Whether you want to learn more about protecting human health, the environment, becoming certified and licensed, or improving your bottom line UNL Extension PSEP can help!

Subsurface Drip

Advantages and Disadvantages of Subsurface Drip Irrigation, EC776 (PDF, 1.2 MB; 8 full color pages) Discusses subsurface drip irrigation, including the advantages of water application efficiency and savings, energy savings and potential yield increases and the disadvantges of initial investment, system capacity, design restrictions and emitter clogging.

Example: Estimating Manure Phosphorus Application Rates

The Nebraska P-Index developed by the University of Nebraska (2006) will be used for analysis. The P Index risk value is the sum of the erosion and runoff components. The interpretation of risk and recommended manure application risk fall into one of four levels: low, medium, high, and very high.

Demonstration Projects

Videos and resources on vegetative treatment areas, wetlands, low water stream crossings, and water quality projects.

Air Quality Issues

The federal Clean Air Act Amendment of 1990 (CAAA) has provisions of importance to producers of agricultural products. Although protecting air quality has inherent implications for livestock and poultry health as well as profitability, the language of air quality is derived principally from environmental regulations designed to protect public health and the use and enjoyment of private property.

Naturally Occurring Elements in Groundwater - Part 3 of a Series - Fluoride

There are naturally occurring elements and minerals within Nebraska geology, and with that, it is not uncommon to find them in Nebraska’s groundwater. This month, the spotlight series continues with fluoride.

Water Optimizer Tool

The Water Optimizer tool evaluates single fields for several crop options. Irrigated crops include: corn, soybeans, sorghum, wheat, alfalfa, edible beans, sunflowers, and sugar beets. Dryland crops include: corn, soybeans, sorghum, sunflowers, alfalfa and wheat in continuous, summer fallow and eco-fallow rotations.

Manure Spreader Calibration

As crops come out of the field, manure application equipment typically begins going in. While knowing the nutrient concentrations in your manure, the nutrient levels in the soil, and the nutrient needs of future crop needs are important, another critical component of the manure application process is using the right manure spreader setting, speed, and lane spacing during application. Combining all of these factors to optimize application efficiency is called calibrating the manure spreader.

VTS Guidance Document

Vegetative Treatment Systems for Open Lot Runoff was developed under the leadership of U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) through an Intergovernmental Personnel Act (IPA) agreement, with collaboration from representatives from several land grant universities, USDA Agriculture Research Service (ARS), U.S. Environmental Protection Agency (EPA), Iowa Department of Natural Resources, Iowa Cattlemen’s Association, and private sector representatives.

Phosphorus Loss

Land application of manure can be beneficial to crop production but can result in increased risk of P loss to surface waters. When manure is applied to meet crop nitrogen needs, the amount of P applied is typically much more than the P removed in the harvest of one crop. Effective January 1, 2007, operators of large CAFOs in Nebraska need to assess the risk of P delivery to surface waters from each of their designated fields by using a P index before manure can be applied.

Calibration Kits

20 kits of equipment and supplies for calibrating both dry and liquid manure spreaders are available in Extension offices across the state. Available for check-out for farmers and their advisors

Contaminant Pathways

Water quality can be degraded by contaminants contained in manure, from water used at milking centers, from silage leachate, and from open lot runoff. These potential pollutants typically follow one or more possible pathways to water.

National SepticSmart Week is September 17-21

National Septic Smart week is Sept. 17–21, 2018. The U.S. Environmental Protection Agency (EPA) uses a week in September each year to focus on improved awareness of proper operation and maintenance of septic systems across the U.S.  The wastewater of approximately 25 percent of the population of the U.S. is treated by on-site or individual wastewater systems. In Nebraska, that statistic holds consistent with approximately 25 percent of our state’s population served by onsite wastewater systems on farms, acreages, suburbs and even some small communities.
