The growing demand for environmental protection and sustainable food production requires the efficient use of organic and slow‐release fertilizers in agriculture. In this study, co‐composting of municipal solid waste (MSW) + three different ratios of natural and Mg‐modified zeolites (5, 10, and 15% on a wet weight basis) is conducted to improve the MSW compost quality. The effects of soil amendment with MSW compost containing natural zeolite (CNZ) and Mg‐modified zeolite (CMZ) on the corn yield, moisture content, leaching volumes, and NO₃‐N concentrations are investigated. Compared to the control (zeolite‐free compost), the CNZ15 and CMZ15 treatments show 39.9 and 49.3% reduction in electrical conductivity and an increase of 64.5 and 110% in NH₄‐N retention, respectively. By using the composts containing zeolite, the moisture content in the surface layer of soil is increased up to 12.6%. Nitrogen uptake and water use efficiency in the CNZ treatment are enhanced by 34.6 and 40.0%, respectively. The increase of the nitrogen uptake and water use efficiency of the CMZ treatment is 54.5 and 55.6%, respectively. Compared to the control, the amount of total NO₃‐N leached from CNZ and CMZ treatments is decreased by 21.0 and 28.9%, respectively. The use of the MSW compost modified with Mg‐zeolite is, therefore, an environmentally friendly solution to prevent surface and groundwater pollution. The modified compost could be also used for the improvement of the physicochemical properties of sandy loam soils.

包含天然和Mg改性沸石的堆肥：对硝态氮淋失，排水和产量的影响

对环境保护和可持续粮食生产的需求不断增长，要求在农业中有效使用有机肥料和缓释肥料。在这项研究中，进行了城市固体废物（MSW）+三种不同比例的天然和Mg改性沸石（以湿重计分别为5％，10％和15％）的混合堆肥，以提高MSW堆肥的质量。研究了含有天然沸石（CNZ）和Mg改性沸石（CMZ）的MSW堆肥改良土壤对玉米产量，含水量，浸出量和NO ₃ -N浓度的影响。与对照（不含沸石的堆肥）相比，CNZ15和CMZ15处理的电导率降低了39.9％和49.3％，而NH _4则提高了64.5％和110％‐N保留。通过使用含沸石的堆肥，土壤表层的水分含量增加到12.6％。CNZ处理中的氮吸收和水分利用效率分别提高了34.6％和40.0％。CMZ处理的氮吸收量和水分利用效率分别提高了54.5和55.6％。与对照组相比，从CNZ和CMZ处理中浸出的总NO ₃ -N量分别减少了21.0％和28.9％。因此，使用经Mg沸石改性的MSW堆肥是一种防止地面和地下水污染的环保解决方案。改性堆肥还可以用于改善砂壤土的理化性质。
