Effects Of Different Organic Fertilizers On Soil Properties

Pot-cultivation was taken in this paper, as herbaceous plant residues,woody plant residues,animal remnant body,animal excrement, we tried to have deep investigations related to the physical, chemic and biologic properties of the organic fertilized soil. We have made researches related to the differences of how the soil changed by the organic fertilized that from different sources, at the meantime it has illustrated organic fertilizers that from different source may have great effects to physical, chemic and biologic natures.The results are showed as follow:1. Only executing the organic fertilizer can change the tendency of the decline of the soil pH value remarkably. Use of woody plant residues and animal excrement can reduce pH value rapidly, but can not last for long-time. The fertilizer originated from herbage residues may reduce slowly, but can last for long time. The animal excrement have great contribution to improve the contents of soil organic material and the maintenance. The usage of herb have influence on the aggregates that are larger than 2mm remarkably, The usage of wood residues have influence on the aggregates that are between 1mm to 0.25mm remarkably, The usage of animal excrement have influence on the aggregates that are between 0.5mm to 0.25mm remarkably, usage of the animal remnant can improve the content of aggregate larger than 2mm and the aggregate between 1mm to 0.5mm. Quantity of the micro-aggregate can be improved remarkably. The use of animal excrement can improve percentage of micro-aggregate that between 0.25mm to 0.05mm remarkably, The use of animal remnant body is great to the nutrient of soil. during the processes single use of fertilizer, the use of woody plant residues improve contents of loosely and stably combined soil humus substances, and ratio of the loosely and tightly. Use of Woody plant residues improve the content of tightly combined soil humus, usage of animal excrement improve ratio of the loosely and stably. Usage of the animal remnant can improve the content of humic acid of the stably and loosely combined, the ratio of loosely stably and tightly combined. The usage of herb residues have great influence on content of fulvic acid of loosely and stably combined. E4/E6 of usage of woody plant residues are greatly improved.2. The organic fertilizer originated from different sources, which was used together dropped the tendency of soil pH. The use of mixture of woody plant residues and animal excrement reduces slowly, but the duration is long. On the contrary, the mixed use of animal remnant body and the animal have great influence on the soil pH value. The mixture of animal remnant body and animal excrement have great contributions to enhancement and the maintenance of soil. The mixture of woody plant residues and the animal remnant body have influence on content of aggregate that are larger than 2mm remarkably, The mixture of herb and animal excrement have influence on content of aggregate that are between 1-0.25mm remarkably, The mixture of woody plant residues and the herb have influence on content of aggregate that are between 0.5-0.25mm, The mixture of woody plant residues and the animal remnant body have influence on content of aggregate that are between 1-0.5mm and large than 2mm, The mixture of animal excrement and the animal remnant body have influence on micro-aggregate content that are between 0.25-0.05mm, The mixture of animal remnant body and other sort of fertilizer have influence on rapid N remarkably, The mixture of herb and the animal remnant body have influence on rapid P content remarkably, The mixture of herb and the woody plant residues have influence on rapid K content remarkably, The mixture of herb and the animal remnant body have influence on total N,P nutrient content remarkably, during the process of mixed using, the use of mixture of herb and woody plant residues improve the quantity and radio of loosely and stably humus. The mixture of herb animal remnant can improve the content unitedly humus. The usage of animal excrement and animal remnant body improve the content of humic acid of the stably combined. The usage of herb and animal remnant body improve the radio of loosely and stably. Usage of herb and Woody plant residues improve the content of humic acid of the loosely combined. Usage of herb and animal excrement improve the content of humic acid of the stably combined. Usage of herb and animal remnant body improve the content of fluvic acid of the unitedly combined. Usage of woody plant residues and the animal remnant body improve radio of E₄/E₆ of humic acid.3. The organic fertilizer(1: 1: 1) and (1: 1: 1: 1) originated from different sources, which was used together dropped the tendency of soil pH value. The use of mixture of herb, animal remnant body and animal excrement reduces slowly, but the duration is long. On the contrary, The mixed use of animal remnant body and woody plant residues, herb have great influence on the soil pH. The mixture of woody plant residues, herb and animal excrement have the great contributions to enhancement and the maintenance of soil. The mixture of herb, woody plant residues and the animal excrement have influence on between 1mm to 0.25mm aggregate content remarkably, The organic fertilizer originated from four source have influence on between 2mm to 0.5mm aggregate content remarkably, The organic fertilizer originated from four source have influence on rapid N content remarkably, The mixture of herb, woody plant residues and the animal excrement have influence on rapid P content remarkably, The mixture of herb, woody plant residues and the animal remnant body have influence on rapid K content remarkably, The organic fertilizer originated from four source have influence on total N,P nutrient content remarkably, usage of herb and woody plant residues, animal excrement can improve the content tightly humus. Usage of herb and woody plant residues, animal excrement improve the content of humic acid of the loosely combined. Usage of herb, animal excrement and animal remnant body improve the content of humic acid and fluvic acid of the stably combined. The organic fertilizer originated from four source have improve the radio of humic acid and fluvic acid of loosely combined. Usage of herb and woody plant residues, animal excrement improve the radio of humic acid and fluvic acid of unitedly combined. Usage of herb and woody plant residues, animal remnant body improve the radio of humic acid and fluvic acid of stably combined. Usage of organic fertilizer originated from four source improve radio of E₄/E₆ of humic acid.4. From the dynamic analysis toward microbial biomass C content, we can conclude that among different use of microbial biomass C content between different use of organic fertilizer, microbial biomass C content can be greatly improved during the processes of using of herb residues. The usage of the four sorts of organic fertilizer can promote the content microbial biomass C remarkably.
