Agricultural Production Animal Manure Management

Land Application

With increasing regulations, the livestock producer needs to understand the scientific principles that affect manure transformations and how to use these principles to manage the manure for maximum fertilizer value with minimal environmental impact. Improved land application of manure is one part of the solution, but we suggest that the producer evaluate the quantity of nutrients arriving on the farm as feed, animals, and fertilizer compared to the total that is exported.

Biological benefits of manure application on agricultural soils

Biological Benefits of Manure Application
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.

Manure Application Options for Beef and Dairy Systems

Typical manure spreader broadcasting manure solid to soil as fertilizer amendment.
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.

Applying Manure Management Concepts On-Farm

LAT flyer preview
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.

Variable Rate Manure Applications Based Upon Management Zones

Variable Rate Manure Applications
There are many challenges associated with variable rate manure applications such as variable nutrient content within the manure source and nutrient availability, application equipment, and prescription methodology. However, in many cases, these challenges are outweighed by environmental and economic benefits from variable rate manure applications.

Manure Phosphorus and Water Quality

Chesapeake Bay experiences summer algae bloom connected with excess phosphorus.
Manure produced in animal feeding operations is a source of fertilizer that can be used to reduce our dependency on commercial fertilizers. Manure contains several essential nutrients that crops that crops rely on to grow, most notably nitrogen and phosphorus. Proper management of manure before, during, and after land application helps to slow down the contamination of our streams and reservoirs.
