Abstract: The fertility changes of soil under different fertilization treatments of a twelve years field trial indicated that the application of compost recycled in a farming system with appropriate amount of fertilizer applied to balance the soil nutrient budget, could not only produce higher crop yields and less surplus of nutrients into environment, but also improved soil fertility with significant increase of soil organic carbon and nitrogen in cultivated layer. However, maintaine higher soil available phosphorus, it was not sufficient just to balance the budget of soil phosphorus, and more phosphorus fertilizer application was needed.
