As poultry genetics, management practices and industries evolve, so do manure and litter characteristics. This presentation was originally broadcast on June 19, 2020. More……
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.…
Designer Manure: Customizing Manure Nutrients to Meet Crop Needs
What if we could create ‘designer’ manures to meet crop needs? This webinar ways to blend commercial fertilizers with manure to balance nutrients. This presentation was originally broadcast on February 21, 2020. More……
Managing manure beyond the farmyard: Manure management for less-typical species and settings
This webinar goes beyond the farm gate and explores how manure and effluent nutrients are handled for some less-than-typical farm-raised animal species. This presentation was originally broadcast on January 17, 2020. More……
Phosphorus Management Lessons Learned from the Field
During this webinar three extension and research leaders for phosphorus management issues shared their experience on critical lessons learned about phosphorus management. This presentation was originally broadcast on December 13, 2019. More……
Watershed Nutrient Inventories – Opportunities and Needs
This webinar focuses on nitrogen and phosphorus inventories at two watershed scales, and how manure nutrients are incorporated. This presentation was originally broadcast on September 20, 2019. More……
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. …
Updating manure N and P credits: A growth chamber study
For a long time, farmers have realized the benefits of using manure as a nutrient source. The ratio of various nutrients in manure, however, rarely matches the exact plant needs. Consequently, farmers must choose between overapplying some nutrients, or underapplying others and meeting the remaining needs with commercial fertilizers.…
Predicting Manure Nitrogen and Phosphorus Characteristics of Beef Open Lot Systems
This project involves the analysis of a new data set for manure characteristics from open lot beef systems demonstrating both average characteristics and factors contribution to variability in manure characteristics among these systems. Defining the characteristics and quantities of harvested manure and runoff from open earthen lot animal systems is critical to planning storage requirements, land requirements for nutrient utilization, land application rates, and logistical issues, such as equipment and labor requirements.…
