In 2008, a 5-year project was established in Bulgaria with the general goal of improving cultivation systems in Bulgaria’s agriculture through efficient and sustainable use of plant nutrients. The project involves five Bulgarian organizations: The University of Forestry, Agricultural University, Nikola Poushkarov” Institute of Soil Science, Executive Soil Resources Agency (Ministry of Agriculture), and the National Plant Protection Service (Ministry of Agriculture). Project activities include: 1) Evaluation of soil nutrient status through summarization of past national soil surveys and more recent localized regional surveys; 2) Systematic summarization of past relevant soil fertility research, existing nutrient uptake and removal information for target crops, and identification of information gaps; 3) Conduct of field nutrient omission plot trials on target crops; 4) Development of tools for site-specific nutrient management that incorporate the national soil survey GIS and other project results into nutrient management software for delivering updated recommendations to farmers and farmer advisers; 5) Outreach activities to assure appropriate use of the developed tools.
