Changes in the physico-chemical properties of soil and harvested soybean seeds in response to soil solarization and bradyrhizobial inoculation

摘要: Field experiments were carried out in 2005 to assess the effect of solarization on physico-chemical properties soil at various depths, and nutrient content two harvested seeds from soybean-bradyrhizobia symbiosis. Experiments organized a Randomized Block Design with levels inoculation three durations solarization. Results indicate that 5 cm depth, increased temperature by 14.5°C, 18°C 16°C, respectively after four, eight 12 weeks, whereas 25 cm it was enhanced 14°C 9.5°C, respectively, 1–2 months over control. The conductivity pH period. sand grain fractionation gradually decreased while clay-size fractions continually duration concentrations consistently nutrients accumulation also improved inoculati...
