Reduction and fate of manure pathogens and antimicrobial resistance

Antimicrobial resistance is a complex issue as it is comprised of not only pathogenic bacteria, but also non-pathogens which share genes within complex environmental systems, such as agricultural fields. This webinar describes potential measures to reduce pathogen and antimicrobial resistance in manure as well as potential fate and transport of manure pathogens and antimicrobial resistance following land application of manure.…

Side-dressing Emerged Corn with Liquid Livestock Manure

The application of livestock manure to farm fields has always been an expense for producers. On-farm research plots were assessed in Ohio following application of  liquid swine and liquid dairy manure using drag hoses to provide side-dress nitrogen to emerged corn. A six-inch diameter drag hose was used to side-dress corn with swine finishing manure at the V3 stage for four crop seasons.

Impacts of New Phosphorous Regulations on Composting of Animal Manures

The Problem

Concerns are mounting in states that have sensitive waterways about the release of P from manure and compost into ground and surface water. P is the limiting nutrient for many freshwater ecosystems and as such regulate the rate of eutrophication and oxygen depletion. The concerns have led to new regulations that limit the application of manure and in some cases compost products that have high concentrations of P.  

Preliminary Study of Sand Settling Lane Designs and Performance

Sand settling lanes are increasing in popularity as a solution for reclaiming sand from the waste stream of dairy facilities.  The purpose of this study was to determine:

    • Whether sand settling systems are functioning properly for Illinois dairy facilities.
    • Whether they meet the criteria in NRCS Conservation Practice Standard (CPS) 632 – Waste Separation Facility.
