Tools for Estimating Load Reductions
- Agriculture Policy/Environmental eXtender (APEX) Model
- The APEX model was developed by Texas A&M AgriLife Research with funding from the U.S. Department of Agriculture’s (USDA) Agricultural Research Service and Natural Resources Conservation Service. The APEX model simulates the environmental and production impacts of various land management strategies for whole farms and small watersheds.
- Nutrient Tracking Tool (NTT)
- Developed by the Texas Institute for Applied Environmental Research (TIAER) with assistance from USDA’s Office of Environmental Markets, NTT estimates nutrient and sediment losses for crop and pasture at the field and/or watershed scales.
