Animal Manure Management

With ground opening up for manure application following wheat harvest, this is a good time to ask about the fit for manure with wheat? There are some good opportunities to use manure following wheat harvest.

A value-added market for woody biomass (wood chips) generated during management of Eastern Red Cedar and native trees in riparian forests and rangeland is critical to offset the cost to landowners of managing forested areas for fire prevention, invasive plant species control, improving wildlife habitat and ecological preservation. Utilization of wood chips alone and co-mingled with livestock manure or nitrogen fertilizer is being investigated (since 2015) as a land treatment practice on local landowner crop fields with research focused on evaluating impacts on soil moisture holding capacity, temperature, biology, & other properties that impact crop productivity.

When a swine lagoon is abandoned, the owner has the choice of decommissioning the lagoon or maintaining the integrity of the lagoon. Decommissioning means dewatering the lagoon and land applying the sludge at the bottom. One cannot just fill in the hole. The process of removing the water and the sludge is time consuming and takes resources and planning to complete properly. One aspect of the process does have some cost recovery and that is utilizing the sludge in a beneficial way.

This article is Part 1 of a two-part discussion on the value of manure. Part 2 focuses on soil quality benefits provided by manure and appeared in the March 6, 2017 CropWatch.

The closure of aged livestock lagoons and earthen manure storage basins needs to be conducted in a manner that controls potential environmental risk and makes economical use of accumulated nutrients in the biosolids. This event will offer a unique opportunity to hear about and see the step-by-step process for planning and conducting a lagoon closure.

Training for Extension professionals, educators and technical service providers to conduct programs and course work on nutrient and manure management and land use within riparian ecosystems.

In Nebraska, routine livestock mortalities can be legally disposed of in five different ways: burial, incineration, composting, rendering, and disposal in a landfill. Regardless of which method is used, it is important to dispose of the animal or animals within 24 hours of death, or sooner if possible. When choosing a mortality disposal method, cost, labor input, and personal preferences usually dictate an individual’s decision.

While tillage has been used to prepare a seedbed, it also destroys the existing root structures in the soil and some of the soil's biological life. Without this biological life, soil structure suffers and many of the nutrients are not as available for crop uptake.

Soil health is defined as the continued capacity of the soil to function as a vital living ecosystem that sustains plants, animals, and humans. Typically, soil health includes three types of soil characteristics: biological, physical, and chemical. Although sometimes used interchangeably, soil quality generally refers to soil chemical and physical properties.

Water quality is affected by nutrient management when chemicals, soil, and residue move off of agricultural land or below it. This section focuses on a number of production issues that when managed correctly minimize the potential for off-site consequences because excess of the nutrients is limited or eliminated.

Odor emission is of great concern to the general public. An odor management plan is required in the permit application for livestock operations with more than 1,000 animal units. Producers need to understand odor emission from animal housing, manure storage and handling, and land application and available management options.
