Agriculture and Economic Benefits of Compost
The application of chemical fertilizers can increase the crop yields quickly, but they also could cause soil hardening and decrease soil organic matter and pH after a long period of application, resulting in loss of soil productivity [55]. However, most proportion of the chemical fertilizers will be ran off or leached due to rain and heavy irrigation, consequently leading to environmental pollution and lower fertilizer effect. Compost is produced from organic waste, which not only contains organic matter but also is rich in micro- and macronutrients. The utilization of compost as a soil fertilizer or amendment could restore the soil quality and improve soil structure and fertility, which not only serves an important role in agricultural production but also is of great significance for improving the ecological environment [56]. Nowadays, using compost as a substitute to chemical fertilizer has become a global consensus. The application of compost could promote soil productivity and improve the crop quantity and quality, as well as increase the income of the farmers.
