Abstract

The research showed that the pH value of Albic soil will reduce in long-term continuous cropping. The decreased range of pH value of applying chemical fertilizer and straw returning to soil were bigger than no fertilization and applying organic fertilizer. The yield of soybean continuous cropping with applying organic fertilizer was significant higher than that with applying chemical fertilizer in Ablic soils, and the chemical fertilizer was higher than straw returning to soil and no fertilization.
