沙丘地土壤地力贫瘠,施用堆肥等有机物质效果显著。日本鸟取县的沙丘土壤改良是以腐殖质含量1%为目标。但沙丘地有机物的分解较快,若想靠施用有机物达到改良土壤的预期效果,必须有大量的有机物。近年来随着地下水道的迅速普及,开始把废水污泥作为有机质用于耕地。为了搞清废水污泥堆肥连用对沙丘地旱田土壤和作物
Sandy soil fertility barren soil, the application of organic matter such as composting effect is significant. Sand dune soil improvement in Tottori prefecture, Japan is targeted at 1% humus content. However, decomposition of organic matter in dunes is faster. If it is desired to rely on the application of organic matter to achieve the desired soil improvement effect, a large amount of organic matter must be present. In recent years, with the rapid spread of underground waterways, wastewater sludge has been used as an organic substance for arable land. In order to clarify the sewage sludge compost used in conjunction with soil and crop on upland fields
