Phosphorus Risk Assessment Index Evaluation Using Runoff Measurements
Published by University of Nebraska – Lincoln’s Livestock Environmental Issues Committee. Manure and composted manure are valuable and renewable resources that can be effectively utilized for crop production and soil improvement. However, runoff from cropland areas receiving manure or compost may contribute to increased phosphorus (P) in streams and lakes. The main factors controlling P movement in surface runoff are transport (runoff and erosion) and source factors such as manure or fertilizer application method and rate, and soil P test level. Elevated soil P levels may result from application of manure at …

Assessing Odor Risk
Odors from animal production operations are a major concern in rural communities. Pressure from the public and the potential impact on the rural economy has caused strong emotional conflicts. Currently livestock producers and urban planning officials have few tools to objectively evaluate scientifically based setbacks between livestock operations and residential areas. Conversely, livestock producers have few tools available to them to demonstrate how odor control technologies can reduce the risk potential of odor incidents.
Recognizing this concern in Minnesota, the Minnesota Legislature provided funds to their University to develop a tool to help predict offsite odor movement …

How much can you pay to have manure applied to your land?
Livestock feeders often need more land for manure application to avoid excessive buildup of soil phosphorus. In some cases, they request payment to reduce transport costs. When is manure a good buy for crop production?
Manure supplies the full complement of nutrients needed by crops and often helps to improve soil biological and physical properties such as the rate of water infiltration. Because of these soil improvements, crop yield is often more with manure application than with fertilizers.
One way of estimating the value of manure is to …

Nitrate contamination of groundwater was first detected in Holt County, Nebraska in the mid- 1960’s. From 1976 to 1990, nitrate-N concentrations increased in 90 percent of the wells sampled by the Natural Resource Districts (NRD) in the county. As a consequence of the concerns associated with this increase, the Holt County Manure Management Education Project was funded by an EPA-319 grant with cooperation among UNL Cooperative Extension, UNL Conservation and Survey Division, USDA-NRCS, the Lower Niobrara NRD, and the Upper Elkhorn NRD. The goal of the project was to educate producers on cropping and manure best management practices to protect …

The Economic Potential of Methane Recovery for Swine Operations: Projected Impacts of Various Public-Policy Scenarios
Economic analyses were performed on anaerobic digestion of manure from finishing operations. The main factors considered were herd size (1,000 head; 3,500 head; and 10,000 head) and method of financial support provided (cost-share program, no-interest loans, tax subsidies, and subsidized electrical sales).
Installation of a digester system is a significant investment that is currently very difficult to justify economically to Nebraska producers based upon consideration of readily quantifiable income and expenses, regardless of farm size. Swine finishing operations looking to invest in this technology would …

Comprehensive Nutrient Management Planning
‘Tools’ for growing season nitrogen management. The pre-sidedress nitrate test, the chlorophyll meter, and the corn stalk nitrate test are three ‘tools’ that are available to farmers and their advisors to improve nitrogen management, both environmentally and economically. To help participants in the 2001 CNMP program become familiar with these tests, we helped them conduct these tests on their manured fields. Most of the manure had been applied without calibrating the spreader or testing the manure.

Manure testing: what to request?
Manure testing is necessary to make optimum use of manure while protecting water resources. The Manure Sample Submission Form requests information required for reliable interpretation of the results.

Interpreting Test Reports of Ground Water Monitoring Wells at Livestock Waste Control Facilities
Some livestock waste control facilities that are required to have an operating permit by the Nebraska Department of Environmental Quality (NDEQ) are also required to install ground water monitoring wells adjacent to the waste control facility. Ground water monitoring requirements are decided on site-specific considerations. Generally, ground water monitoring may be required where the depth to water is shallow, sediments are sandy, the livestock facility is located in a public water supply’s Wellhead Protection Area, or any combination of these and other factors listed in Chapter 13 …

Property Valuation May Be Reduced by Proximity to Livestock Operation
In Nebraska, land and buildings are valued at their fair market value for purposes of property taxation. Residential and commercial real estate is valued at 92-100% of actual value (i.e. farm market value) and agricultural real estate is valued at 74-80% of actual value. NRS 77- 5023(3). Fair market value for property tax valuation purposes may be determined by (1) comparative sales, (2) income or (3) cost. NRS 77-112. In Livingston v Jefferson County Board of Equalization, 10 Neb App 934 (2002), the Nebraska Court of Appeals ruled that …
