CHANGING CHARACTERISTICS DURING COMPOSTING AND INDICATIVE QUALITY VALUES OF THE FINAL PRODUCT

Abstract

Soil is a very valuable resource that humanity needs for its survival. In order to meet food demand, the agricultural sector has promoted intensive production, resulting in overexploitation and degradation of the soil. The incorporation of organic fertilizers, such as compost, has proved to be a good alternative to mitigate soil damage. However, the use of composts that do not meet quality standards can cause adverse effects. Therefore, it is of vital importance to know the changes and criteria to be considered in the composting process to produce high-quality organic fertilizers, capable of providing benefits to the physical, chemical and biological characteristics of the soil. The objective of this review was to compile information about changes in the composting process, and criteria and methodologies used to determine the quality of composts and ensure the benefits of their use.
