  <dc:title>XDA28090106 Dataset on Safe Utilization of Organic Manure and Efficient Cultivation of Soil Fertility</dc:title>

  <dc:description>This dataset contains the changes in maize grain yield over five consecutive years under different treatments involving the substitution of chemical fertilizers with composted chicken manure and piled organic fertilizers at various ratios. It monitors the content changes of ammonium nitrogen and nitrate nitrogen in the 0&amp;ndash;40 cm soil layer over four years following substitution. After five years of experimentation, soil physicochemical indicators&amp;mdash;including soil organic matter, total nitrogen, total phosphorus, total potassium, available phosphorus, rapidly available potassium, pH, and bulk density&amp;mdash;were analyzed for each treatment. This provides data support for evaluating the safe utilization of organic manure and the effectiveness of efficient soil fertility cultivation.</dc:description>
