Abstract:
Composting is the preferred treatment method for many types of organic wastes from both ecological and economical standpoints. The most common raw materials for composting are municipal solid waste, sewage sludge, wastes of the timber and food processing industries and animal excreta. The main reasons for composting vs. other treatment methods are: It is an effective method of drying and reducing the mass and especially volume of wastes, to be transported to landfills while minimizing the risks to the environment. The end-product of the process can serve as a soil amendment, having beneficial physical, chemical and biological effects on the soil and on crops. Compost may be used effectively for the reclamation of infertile soils such as calcareous, dispersed and impoverished soils. It is possible to produce special, high-value products such as growing substrates from certain raw materials. Horticulture and especially organic agriculture are using increasing quantities of composts of various types. In terms of volume the most important application is to soil-grown fruit trees and vegetables. Compost contributions to the soil-plant system are diverse: Several organic molecules (e.g. polysaccharides and humic acid) improve soil texture through their effect on aggregation of clay particles. As the added organic matter is a substrate for soil microorganisms, it enables, through their activity, enhanced nutrient cycling and weathering of soil minerals. Composts contain considerable amounts of nutrients that can supplement plant nutrition. Compost may suppress soilborne plant pathogens, mainly through the activity of antagonistic microorganisms. Composts may exert direct enzymatic or hormonal effects on plant roots, inducing growth promotion. In compost-containing growing media, all these effects except for the first one are manifested in a more pronounced manner, due to the increased compost fraction in the rhizosphere. Compost effects on the soil-plant system are briefly discussed as related to the most common compost uses in horticulture.
