Assessment and Monitoring Nutrient Flows and Stocks to Determine Appropriate Integrated Nutrient Management Strategies: Technical report on the study approach and preliminary results of NUTSAL project, 1998/99. pp 28. https://kalroerepository.kalro.org/handle/0/7049.https://kalroerepository.kalro.org/handle/0/7049The National Soil Plant Nutritional (NSFPN) Research Programme has the mandate to contribute towards increased agricultural production in the high, medium and low rainfall areas in Kenya. This constitutes 44.6 million hectares of land of which only about 8.6 million ha is high to medium potential. The rest is either semi-arid or arid. The programme aims at increased crop production through integrated nutrient management approached under different cropping systems and appropriate tillage practices. Improved production of crops and livestock in a sustainable manner is a key to agricultural development in arid and semi-arid lands.enhttp://creativecommons.org/licenses/by/3.0/Report28SoilMethodologyNutrientsLand use
