Mapping Regional Mineral Status in Ohio Beef Cattle

Commodities

Practices

This project combines research, demonstration, and Extension outreach to address a critical but poorly characterized issue in Ohio beef production: regional variation in mineral availability from forage, soil, and water, and its impact on cattle health, reproduction, and supplement efficiency. Producers often rely on generic mineral programs that may not match their local environment, leading to deficiencies, unnecessary costs, and excess mineral loading of soils and water.

Through coordinated sampling of forage, soil, water, and liver tissues across six physiographic regions of Ohio, this project will generate the first statewide dataset linking environmental mineral supply to herd mineral status. Core farms will receive individualized mineral evaluations, implement revised supplementation programs, and demonstrate results through regional field days. Technical farms will contribute additional environmental samples to build a robust "Ohio Beef Mineral Map" accessible to all producers.

This project is innovative in its integration of environmental sampling, biological validation, and on-farm demonstration, providing both science-based recommendations and practical examples of improved mineral management. Expected impacts include increased producer knowledge, improved supplement efficiency and economic returns, reduced over-supplementation and nutrient waste, and improved quality of life through clearer decision-making tools. Participating farms represent cow-calf operations typical of each targeted region in Ohio.

1. Partner with six beef producers across Ohio's six geographic regions to collect and analyze forage, water, soil, and liver samples to identify regional variation in beef cattle mineral status.
2. Develop a statewide "Ohio Beef Mineral Map" illustrating regional mineral strengths, deficiencies, and antagonisms.
3. Provide each participating farm with individualized mineral interpretation and recommendations for herd management.
4. Implement and evaluate revised mineral supplementation strategies on each core farm in Year 2, tracking herd mineral status and supplement costs.
5. Conduct producer outreach through field days, factsheets, and digital resources to share results statewide.
