Evaluation of quality of fertilizer produced with compostage comprising organic materials and ground rock

Abstract

For thousands of years different peoples managed an agriculture based on material available on rural sites. One method was the production and use of organic compounds. Current research evaluates the quality of organic compounds produced from nutrients found in a rural property. Prime matters used for the production of fertilizers were bovine dung, sawdust, coffee bean husks and rock powder. Compost started by ratio C:N between 25 and 35 and ended with C:N less than 15. Aeration of conditioner required a composter, whilst the humidifier was a water tank. Chemical, organic, biological and sanitary analyses show that the compost process occurred correctly. Compost had most minimum guarantees for being a Class A organic fertilizer compost which may improve the soil´s physical, chemical and biological conditions with an increase of autonomy for the farmer and lessening of his dependence on fossil fuel.
