Two Key Livestock bills Before NE Legislature
State senators have advanced LB 210 to Select File on a 39-1 vote. The proposed legislation would exempt certain farm and ranch laborers from the Worker Compensation Act. Generally, employers of farm and ranch laborers would be exempt from providing workers’ compensation coverage if their employees are related to the employer and if the total number of employees not related to the employer does not exceed five. In the event an agricultural employer employs six or more unrelated, full-time employees the employer may still be exempt so long as less than 40% of …

Integrating Animal Feeding Decisions into CNMP Processes: Part 1
Environmental planning in animal production systems often requires an estimate of nutrient excretion. Standard values published by the Natural Resources Conservation Service (NRCS) (SCS 1992), American Society of Agricultural Engineers (ASAE 1999), and MidWest Plan Service (MWPS 2000) commonly have been used for this purpose. However, these current procedures do not reflect the impact of producers' animal dietary decisions on nutrient excretion. The increasing variety of feed ingredient options, changes in nutritional programs to match improving genetic potential, and feeding strategies designed to reduce nutrient excretion are influencing the amount of …

New EPA Rules Targeting Livestock and Poultry Industry Congress passed the Clean Water Act (CWA) in 1972 to "restore and maintain the chemical, physical, and biological integrity of the Nation's waters." Among its core provisions, it prohibits the discharge of pollutants from a point source to waters of the United States except as authorized by an NPDES permit. EPA's regulation of concentrated animal feeding operations (CAFOs) under the CWA dates to the 1970s. EPA established effluent guidelines for feedlots in 1974 based on the best available technology that was economically achievable for the industry. CAFO regulations issued in 1976 determined …

Reducing Spatial Variability of Soil Carbon and Phosphorus by Site-Specific Manure Application
Spatial variability can significantly influence crop performance across a field. Manure, a renewable resource, is an excellent source of nutrients that can be substituted for synthetic types of fertilizers. The carbon (C) and nutrients in manure can enhance the physical and chemical properties of soils, especially infertile soils, hence reducing soil spatial variability. Organic C constitute about 58% of organic matter in the soil (%OM = %OC x 1.724). Manure application not only provides nutrients for crops but also improves soil quality since the organic matter in manure …

The New CAFO Rules: What is Required in a Nutrient Management Plan?
As a part of the U.S. Environmental Protection Agency’s (EPA) Concentrated Animal Feeding Operation (CAFO) Final Rule, all CAFO owners are required to apply for a National Pollutant Discharge Elimination System (NPDES) permit. Part of the process includes developing and implementing a Nutrient Management Plan (NMP). At a minimum, an NMP must include Best Management Practices (BMPs) and, for large CAFOs, procedures necessary to achieve effluent limitation guidelines (ELGs).

Excerpt from Seabiscuit
The halcyon days at the Tijuana track came to a spectacular end. On the backstretch early each morning men guided teams of horses on circuits of the barns, shoveling the mucked-out manure into wagons and driving the teams up the hill behind the backstretch, where they would dump it. The pile had been accumulating since 1917, and because the city received little rain to wash it down, it was enormous. “Oh my gosh.” Remembered trainer Jimmy Jones. “ It was as big as the grandstand.” Inside its depths, the manure fermented, generating scalding heat.
To the locals, …

Land Application Setback and Buffer Requirements for NPDES Permitted Large CAFOs
Large Concentrated Animal Feeding Operation (CAFO) owners/operators are required to implement setbacks, buffers, or an alternative conservation practice on all fields to which manure is applied. This newsletter discusses the federal rules and some guidance on how the rule may be applied to land application sites. The setbacks and buffer requirements apply to large CAFOs only. Most states are authorized to implement the CAFO program and may have additional, more stringent requirements. Check with your state permitting authority to determine the requirements that apply to your operation.

Low Water Stream Crossings for Cattle (LWSC)
Livestock access to streams, specifically, cattle access to streams in pastures has become of concern in the development of Total Maximum Daily Loads (TMDLs). There is very little information available to planners on the contribution of nitrogen, ammonia, phosphorus, and human health-related microorganisms to stream segments from rangeland cattle. A common modeling solution in the development of TMDLs is to exclude livestock from streams in order to reduce nutrient loads. Although this approach seems simplistic, it is problematic for owners and managers of rangeland livestock.
Many producers are now choosing to supply water …
