Abstract
In recent years the use of chemical fertilizers, have adverse environmental effects and consequences on the health of humans and other living organisms. Compost is a mixture of organic materials processed, for a long time due to certain unique Moderators effects on characteristics of physical, chemical and biological of soil and thus grow and increase the product has been beneficial. Formless of compost, provides many problems in distributing them at ground level or at the time of mixing with other potted mixtures. The use of pellets compost is one of the ways to resolve this problem. The aim of this study was examine the contents of the composting of organic materials and other waste produced by the larvae of Potosia cuprea and compare them with the vermicompost and capabilities pellets they were chosen by the larvae. For this purpose, kitchen waste, leaves of vines, mulberry, cut lawn, and mixtures of different leaves (figs, paulownia, mulberry and grapes) were used. Results showed that the highest electrical conductivity, organic matter, total nitrogen, potassium and phosphorus was obtained in compost the kitchen waste. The highest pH, converting the waste to composting and compost uniformity were related to cut lawn. The results showed that the larvae Potosia cuprea had a significant impact on the production of pellet compost. Although pH and electrical conductivity in produced Compost, were higher than vermicompost but, the top of other content and pellets, the use of which makes it possible.
