The Comprehensive Economic and Environmental Optimization Tool - Macro Modeling System (CEEOT-MMS) was developed by researchers at the Texas Institute for Applied Environmental Research (TIAER) to help evaluate the implementation of agro-environmental policies or practices on large scales. Recently, CEEOT-MMS was applied to evaluate the impacts of three alternative manure nutrient management options when implemented on all animal feeding operations (AFOs) in Texas. The three manure nutrient management options were manure application at the nitrogen uptake rate of receiving crops, manure application to supply all of crop phosphorus (P) requirements with manure ortho-P (a High P rate), and manure application to supply all crop P needs with manure total P (a Low P rate).(Download PDF) (Export to EndNotes)
