Outline of Final Research Achievements

To investigate long-term trend of fertility status of paddy soils in tropical Asia after the “Green Revolution”, soil samples were collected from almost same locations of the previous research about 50 years ago in Thailand, Philippines, Malaysia and Bangladesh, and their fertility-related properties were analyzed. Considerable increase in available phosphorus was observed in all the countries and the changes in pH and organic matter content was not conspicuous. Significant decrease in total potassium was observed in Thailand. As a consequence, it was concluded that fertility status of paddy soils in tropical Asia has increased in general during the past 50 years but soil nutrients whose removal is accelerated due to higher yield of rice should be replenished appropriately to keep rice production in tropical Asia sustainable.
