  • Changes in soil, flora and fauna in rice paddies under continuous organic farming with no agrochemicals inputs，2014.07 - 2018.03，Changes in soil, flora and fauna in rice paddies under continuous organic farming with no agrochemicals inputs

    Studying an organic rice farming system developed by a farmer, we found the following mechanisms of this system.
    This organic farming system is very labor-efficient due to the omission of fertilizer applications and weeding, which greatly contributed to this farm's economic sustainability.
    The rice yield was much lower only a few years after conversion to this system than that in conventional farming, but the former yield approached the latter as the practice is continued for several years. One of the reasons for this increase of rice yield due to the continued organic management is the increased availability of soil nitrogen and phosphorus as the off-season weeds are incorporated across the years. The continued practice of organic farming also reduced the population of a summer-season weed species and increased the population of natural enemies like spiders.
