The Nutrient Tracking Tool (NTT) compares agricultural management systems to calculate a change in nitrogen, phosphorous, sediment loss potential, and crop yield. Agricultural producers and land managers can enter a baseline management system and an alternative conservation management system and produce a report showing the nitrogen, phosphorous, sediment loss potential, and crop yield difference between the two systems.

Due to improvement of the underlying science, changes in APEX, and new functions in NTT, this program is occasionally upgraded. Therefore, for the convenience of users that used previous versions of NTT, the current as well as previous versions of NTT are available to all users.

The Nutrient Tracking Tool was designed and developed by the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS), the USDA Agricultural Research Service (ARS), and Texas Institute for Applied Environmental Research (TIAER).
