Abstract: In order to promote the security of manure application to field,this study estimated the suitable area of cropland needed by manure application,total nitrogen and phosphorus load of cropland and the potential of using manure from growth of main crops in Hubei province.The results showed that,planting rice called for smallest cropland area for reusing manure.In the other word,rice owned the strongest capacity to take manure nitrogen and phosphorus away from field.From the perspective of regulation of fecal pollution,the manure nitrogen and phosphorus load per unit area of arable land in Huanggang city were maximum in Hubei province,and they had surpassed the EU′s standard of limitation on nitrogen and phosphorus which were 170,35 kg/hm²,respectively.Closely followed by Ezhou and Xiangyang city,which should be focused on.From the potential of manure application to field,less space was left for manure application in Shennongjia Forestry District,Huanggang city and Enshi city.Therefore,the total amount of livestock and the proportion of manure applied to cropland should be controlled in these regions.
