Precision Technologies for Managing Manure

This webinar explores in-field measurements of nutrient concentrations and discusses how precision technologies impact agronomic and water quality management decisions as well as pave the way for automating record-keeping and removing human error from applications. This presentation was originally broadcast on April 17, 2020.…

Nutrient Planning on Swine Farms

Introduction

Thirteen swine farms demonstrated significantly better nutrient management over previous studies as measured by Whole Farm Nutrient Balance. Feed program for phosphorus, manure storage selection, and nutrient plan implementation proved to be the most critical factors.

Environmental Benefits of Manure Application

For centuries, animal manure has been recognized as a soil “builder” because of its contributions to improving soil quality. Environmental benefits are possible from manure application if manure and manure nutrients are applied and timing and placement follows best management practices. When compared to more conventional fertilizer, manure properly applied to land has the potential to provide environmental benefits including:

  • Increased soil carbon and reduced atmospheric carbon levels
  • Reduced soil erosion and runoff
  • Reduced nitrate leaching
  • Reduced energy demands for natural gas-intensive nitrogen(N) fertilizers

Manure Effects on Soil Organic Matter

Manure contains most elements required for plant growth including N, P, potassium, and micronutrients (Manure as a Source of Crop Nutrients and Soil Amendment).…

Separation Technologies for Capturing Nutrients from Manure

Exporting phosphorus and possibly nitrogen from larger livestock operations as well as regions of large livestock populations is often essential for protecting water quality. Solids (and nutrient) separation technologies are an option for concentrating nutrients for export. This webinar introduces three approaches to solids separation that are being applied in commercial settings.…
