ECONOMIC AND ENVIRONMENTAL EVALUATION OF DAIRY MANURE UTILIZATION FOR YEAR ROUND CROP PRODUCTION

The production of excess on-farm manure is placing continuous pressures on dairy producers to meet or exceed standards for environmental regulations while maintaining profitability and competitiveness. Evaluation of the effects of recycling nutrients on the profitability of the whole farm enterprise is important for a dairy operation. The objective of this study was to develop a linear programming model that evaluates the economic performance of a dairy operation considering production and environmental constraints. The main goal was to maximize profits from the dairy enterprise considering milk production, manure production, crop production while maintaining a balance of nutrients in the system. Results from simulation analyses showed greater effects on total farm profits at the more restrictive P-based than N-based manure application rates.
