From Livestock and Poultry Environmental Learning Community:
Webinar: Optimizing Agricultural Practices: Balancing Manure Use and Minimizing Compaction | April 19 @ 2:30 pm ET | Learn about the challenges of soil compaction, how manure can contribute to it, and ways to minimize the damage, or even remedy it.  |  Details

Webinar recording: Implications of Managing Manure on a Nitrogen Basis | Three recordings cover assessment tools for whole farm balance of N and P, drawdown of legacy P, and impacts of N based manure application on zinc accumulation in soils. |  Recordings

From OMAFRA’s Manure Mondays:
Webinar recording: Science of Soil Health | Discussion of the effects of applying sand-laden manure to cropland.  |  Recording

From Buckeye Dairy News:
Using dairy manure with newly planted corn and soybeans | Applying liquid manure after planting can help alleviate issues with soils that may be too wet or dry. However, consideration of timing and application method need to be considered.  |  Article

From Ohio Country Journal:
Strip-till and sub-surface nutrient placement in Ohio | John Fulton, OSU, discusses benefits and equipment types for precision placement of nutrients. Note that these methods can be used for liquid manure as well as fertilizers.  |  Article

From SWCS Conservation NewsBrief:
Is it time to up your ‘soil health game’ with livestock? | The ‘Match Made in Heaven: Livestock + Crops’ project is working with stakeholders to gain insight into the effects of Integrating livestock with crop production, including practices such as grazing on cover crops or crop residues, on soil health.  |  Article  |  Project website

From Manure Manager:
The manure crystal ball | Three manure experts’ predictions for what’s ahead include improvements in manure handling and application equipment, use of the manureshed concept to improve nutrient balance in an area, workforce challenges, and more.  |  Article

Check it out: How satellites and AI can detect illegal manure spreading in Wisconsin | While AI evaluated satellite images to accurately identify illegal manure spreading on snow covered fields, it has raised questions, including the accuracy of AI, need for human verification, fairness of Wisconsin’s winter application rules, privacy concerns, and others.  |  Article

Research: The impact of extreme precipitation on nutrient runoff | A Wisconsin study found that extreme precipitation events have higher increases in nutrient runoff in areas with livestock and crop production. However, about 27% of the ammonia and 47% of the P increases were attributed to legacy nutrients. Cover crops and other conservation measures can help reduce the risk.  |  Article
