Adoption of the Nutrient Management Support System
Software Throughout Latin America

Principal Investigator(s):

  • T. Jot Smyth - North Carolina State University
  • Deanna L. Osmond - North Carolina State University

The goal of this project is to support the adoption of the Nutrient Management Support System (NuMaSS) software’s knowledge on nitrogen, phosphorus and soil acidity management via a network of on-going programs throughout Latin America. Specific objectives are to:

  • test and compare NuMaSS predictions on nutrient diagnosis, recommendation and economic evaluation to those currently in use;
  • identify and refine software components that limit adoption of the NuMaSS knowledge base;
  • monitor the local adoption process and develop auxiliary tools, when needed, that improve the use of NuMaSS-knowledge within the regional user domains.

Activities in collaboration with national and international institutions are being conducted in Bolivia, Brazil, Costa Rica, Ecuador, Honduras, Mexico, Nicaragua and Panama.
