Animal Manure Management

This is a summary of the webinar “The Role of the Odor Footprint Tool in Livestock Nuisance Litigation” given on Jan. 21, 2021, as part of the University of Nebraska-Lincoln’s Department of Agricultural Economics Extension Farm and Ranch Management team’s weekly webinar series.

Vegetative Treatment Areas (VTA) are used in multiple Nebraska cattle operations to help improve and maintain water and nutrient quality. This article will explain what a VTA is and how it works. It will then detail how valuable nutrients contained in the manure will be captured and reused. It will also describe what size of feeding operations should install a VTA. Lastly, it will detail how a producer can get assistance to install one.

This year’s Land Application Recertification sessions, called Applying Manure Management Concepts On-Farm, are scheduled to be in-person at many locations across the state in June, with one taking place in May in Lexington. Manure trainings earlier this year were held virtually, but we’re making progress, and that means we’re looking forward to seeing everyone in-person for the next manure event.

Dietary nutrients, specifically nitrogen and phosphorus, are excreted in manure from feedlot cattle. Dietary strategies, including calculated protein supplementation and phase-feeding programs, can be implemented by cattle feeders to decrease nutrient excretion and improve nutritional efficiency of the animal.

When it comes to animal manure from feedlots being applied to the land in Nebraska, developing management practices that efficiently uses the nutrients from manure while being environmentally sustainable can be a complicated process. This article introduces some land application approaches for beef and dairy feedlot systems.

Groundwater is often the main source of drinking water for rural communities, especially in the Midwestern United States, so it is important to keep that water at levels that are safe to drink while minimizing environmental impacts. Although animal manure has many benefits to farmers, it can contaminate groundwater supply if not managed properly. This article discusses important considerations when storing and applying manure and includes requirements for testing of well water.

This article outlines the process of production and benefits of utilization of biogas from manure for small scale animal farmers, especially those in developing countries. Apart from the sanitary benefit of proper management of manure, this article highlights other benefits that can be derived from animal manure. Thus, encouraging these farmers to store manure from their animal farms for use, thereby changing waste to valuable resources.

Soil quality has been traditionally described in terms of chemical and physical properties; however, soil organisms play an important role in soil health. Some studies suggest that using manure as soil amendment could result in increased microbial biomass, which results in higher soil bacteria, fungi and higher microbial activity. Soil microbial activity is crucial for nutrient cycling, aggregate stability, fertility, and other soil characteristics leading to better crop productivity.

With silage harvest coming up quickly, manure application will soon follow. Because silage is often the first crop to come off the field, it allows for earlier manure application and thus an earlier cleanout of pens before winter. As that manure application plan develops, include best stewardship practices for optimum rates and preferred application methods in final decisions.

Fertility is critical to a good crop, so we know not to ignore our crop fertility needs, but we don’t always think about ways we may be able to trim costs by better utilizing local nutrients. Manure has many benefits, including some related to soil health, but perhaps the most recognized benefit is that manure contains the nutrients our crops need. Manure isn’t always an inexpensive product, but it contains multiple nutrients that are highly valued when planning your fertility program.
