| Abstract: |
| Lack of integrated planning of both crop planting and livestock raising systems causes excessive outputs of livestock feces, leading to serious hazards to the ecological environment. Here we explored the linkage of agricultural pollution to material cycling between crop-planting and livestock-raising. We also discussed the approaches to achieve simultaneous development of crops and livestock in two aspects of “Crop-planting determines livestock-raising” and “Livestock-raising promotes crop-planting”. “Crop-planting determines livestock-raising” means that the scale of livestock system should be reasonably determined by crop system according to the law of material cycling between two systems, with an aim at relieving the environmental pressure caused by livestock wastes. “Livestock-raising promotes crop-planting” is that applying livestock wastes after their harmless treatments would improve soil fertility and crop production. It is concluded that balancing production between “crop planting and livestock raising” would fully utilize wastes, reduce the risk of environmental pollution and ultimately achieve the goal of agricultural pollution reduction. |
