Interpreting fertilizer use efficiency in relation to soil nutrient-supplying capacity, factor produfficiency of on-farm management of N and other nutrients. In 1994, IRRI initiated its Mega Project on Reversing Trends of Declining Productivity in Intensive Irrigated Rice Systems in selected rice production domains of five tropical Asian nations to improve on-farm fertilizer use efficiency and to

Resource management options for upland areas of Indonesiairst steps for developing intensive and sustainable upland farming systems. Because upland environments are fragile, nutrient management should be an integral part of upland conservation farming. Low-cost technology is the most preferable choice because most farmers in upland areas are relatively po

Soil and crop management technologies for enhancing rice production under micronutrient constraintsence created for rice cultivation influences electrochemical and biochemical reactions, and alters pH, pCO. and the concentration of certain ions. This environment increases the availability of Fe and Mn with concomitant decrease in Zn and Cu. It is well known that Zn deficiency is predominant in lo

Strategies for developing and promoting innovative fertilizer formulations for efficient crop producrients. Raw materials for fertilizers and soil amendments differ in quality. The use of local resources should increase in importance, but global scarcities are not expected within the next generation. Because of variations in climate, soil fertility, and crop requirements, the need for nutrients va
