The information contained in NTT (Nutrient Tracking Tool) has been tested for use in the Ohio counties surrounding Lake Erie, in the Mississippi Delta, Missouri, Yakima County in the State of Washington, the northern portion of Oregon, Maryland, Delaware, Pennsylvania, Virginia, Puerto Rico, and Sonoma County in California. Because your area of interest may contain unique features, the program may not provide the appropriate results in your area when model default parameters are used. All input data and results should be carefully reviewed as errors or omissions in the input data may lead to misleading outcomes. We are currently in the process of completing the testing and validating NTT across the US (this page will be updated accordingly as new information becomes available).
If you have questions regarding the application of NTT or are interested in having it calibrated and validated for your area, please contact Dr. Ali Saleh at (254)592-1975 (saleh@tarleton.edu) or Ms. Mindy Selman at (202) 401-0531 (mselman@oce.usda.gov).
Finally, although NTT has been tested by its developers, NO warranty, expressed or implied, is made as to the validity of the results and functioning of the program and related program material, nor shall the fact of distribution constitute any such warranty; and NO responsibility is assumed by the developers in connection therewith. The user assumes all risks and responsibilities for the use and application of NTT and interpretation of the results generated from the tool. The authors and their affiliated institution, TIAER, Tarleton State University, and any other U.S. Government agencies will NOT be liable to NTT users for any damage, including lost profits, lost savings, lost time, actions by regulatory agencies, or any other direct or indirect incidental or consequential damages occurring from the use of or inability to use NTT, its databases, its results, or its documentation for any purpose.

Thank you for your interest in using the Nutrient Tracking Tool (NTT) program. NTT is a free, online, user-friendly decision-making tool. NTT has been developed to assist producers selecting the most cost-effective management practices to minimize the nitrogen, phosphorus, soil carbon (sequestration) and sediment losses from crop, pasture, and forest lands while optimizing the crop production. NTT has been developed by the modeling team of Texas Institute for Applied Environmental Research (TIAER) at Tarleton State University in cooperation with USDA’s Office of Office of the Chief Economist, Natural Resource Conservation Service (NRCS), and Agricultural Research Service (ARS). NTT program is available for major cropping systems in US States (with exception of states of Hawaii and Alaska).
