[Method] N balance of farmlands after manure fertilized was researched in a hoggery in Beijing （600 base sows and 647 breeding pigs）. [Result] The suitable N input in neighboring farmlands was 191.9 kg/（hm 2 ·y） and the farmland area satisfying balance between growing and breeding was 53.7 hm 2 in the hoggery. [Conclusion] The research provided a scientific method for balance between growing and breeding.展开更多
