Rice and problem soils in South and Southeast Asia

Rice and problem soils in South and Southeast Asia

D. Senadhira

In South and Southeast Asia, about 100 million ha of land suited to rice production are uncultivated because of soil problems such as salinity, alkalinity, strong acidity, or excess organic matter. About 23 million ha of these lands are potentially cultivable, provided tolerant varieties are available. In addition, about 50 million ha of cultivated land exist where deficiencies of zinc, phosphorus, or iron, or excesses of aluminum or iron limits rice yields.
