The Influence of the Mushroom Compost Application on the Microorganism Quantity of Reclamated Soil

The mushroom compost which was produced from farm can be used to improving the quality of the reclamated soil. On the one hand, the question about environmental pollution made by the mushroom compost is solved, and on the other hand, it can improve the quality of the soil. In addition to the quality of the soil can be expressed by nutrient content. It also can be expressed by the number of microorganisms in the soil. At the same time, different fertilized time have different impact on soil quality. This article choice Zhoucheng City which was completed the reclamation in 2002 for study, research difference in timing of the application of mushroom caused the difference change in the number in soil bacteria, fungi and actinomycetes. which reflect the difference in timing of the application of changes in soil quality. With the depth of the soil increased, the number of micro-organisms is decreased. The area which were fertilized mushrooms compost in 2006 have the largest number of micro-organisms, un-fertilized area and the area which was fertilized in 2007 have smaller number of micro-organisms, and mushroom compost have different effect on the number of bacteria, fungi, and actinomycetes.
