Principal Types of Low Yield Paddy Soil in China

Conference paper


Paddy soil is widely distributed in China, with a total area of 26 million hectares. Due to different natural and cultivative conditions, the rice yield varies in different regions, ranging from 10 tons per ha annually in highly productive regions to only 2–3 tons per ha in regions of low productivity. Besides the agricultural techniques, unfavorable climatic and soil conditions are the causes of its low productivity. Among these factors, the soil conditions are frequently especially important in affecting the yield.
