有机肥在农业发展进程中越来越受到人们的重视，在改善和提高土壤肥力同时可促进农作物优质和高效生产。有机肥含有丰富的有机、无机养分，对减少化肥施用有着不可替代的作用。在内蒙古东部、西部地区采集包括鸡粪、羊粪为主116份肥料，其中有机肥原料74份，商品有机肥42份。在有机肥原料羊粪、牛粪、鸡粪中检出重金属，其中1份羊粪样品铅超标，含量373.2mg/kg。商品有机肥均有重金属检出但未超标，除重金属锌外商品有机肥中重金属均高于原料，以羊粪为主生产的商品有机肥重金属含量高于羊粪和牛粪混合。内蒙古地区有机肥原料、商品有机肥整体情况较好。

Organic fertilizer is increasingly valued in the process of agricultural development. It can improve and enhance soil fertility while promoting high-quality and efficient crop production. It contains rich organic and inorganic nutrients and plays an irreplaceable role in reducing fertilizer application. The data set included the content of organic fertilizer raw materials and heavy metals in commercial organic fertilizer in Inner Mongolia. In the eastern and western parts of Inner Mongolia, 116 fertilizer samples(including chicken manure and sheep manure), 74 organic fertilizer raw materials and 42 commercial organic fertilizer samples were be collected. Sheep manure, cow manure and chicken manure of organic fertilizer raw materials were all be detected. One sheep manure sample contained 373.2 mg/kg lead which is exceed standard. The commercial organic fertilizer were all be detected heavy metals but not exceed standard. The content of heavy metals in commercial organic fertilizer was higher than raw material except zinc. The content of heavy metals in sheep manure was higher than that in the mixture of sheep manure and cow manure. Inner Mongolia organic fertilizer raw materials, commercial organic fertilizer overall situation is preferably.
