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.

Manure Improves Soil Health and Provides Yield Stability and Reliability

Cattle manure is a valuable resource for farmers, as it contains an abundance of macro and micronutrients that are essential for plant growth and development. The nutrients present in manure, such as nitrogen (N), phosphorus (P), potassium (K), and other minerals are essential for soil fertility. One of the most significant advantages of using cattle manure as a fertilizer is that it can enhance the soil organic matter (SOM) content. Soil organic matter plays a crucial role in improving soil structure, water-holding capacity, and nutrient availability. Moreover, cattle manure can also increase the changeable fractions of carbon (C) & nitrogen (N) and enhance soil microbial activity, which is crucial for the decomposition and stabilization of soil organic carbon (SOC). The Knorr Holden plot, located at the Panhandle Research, Extension, and Education Center, Scottsbluff, Nebraska presents a unique opportunity for studying the impact of long-term manure (more than 77 years) applications on soil health and crop productivity.

Calculating the Value of Nutrients in Manure

“How much is this manure worth?” This is a common question from both livestock farmers who are supplying manure and crop farmers who are utilizing it. To answer this question, it is important to understand the difference between gross value and net value. The gross value of manure reflects the equivalent commercial fertilizer value of the nutrients contained in the manure. The net value considers the impacts of application method, transportation, and cropping system nutrient needs as well as intrinsic values that are much more difficult to put a number on. Therefore, this article will focus on determining the gross value of nutrients in manure.
