The NTT Model

The team at the National Center for Water Quality Research at Heidelberg University is using the Nutrient Tracking Tool, or NTT, to model the effects of conservation practices on dissolved reactive phosphorus on each field enrolled in PLUS-UP. Developed by the Texas Institute for Applied Environmental Research at Tarleton State University, NTT is a powerful tool for estimating the nitrogen, phosphorus and sediment losses from cropland and pasture.
NTT is available online and draws on a comprehensive soil database, making it extremely accurate on a field scale. The model includes a wide range of crops, rotations, nutrient and management options that allow users to calculate economic and environmental outcomes based on real-world data. The versatility and accuracy of NTT make it an ideal tool for quantifying the effects and calculating payments under the PLUS-UP program.
NTT is available online for use by farmers and ranchers as well as scientists. Click here to learn more about NTT.
