Production of agri-food derived compost, soil and plant responses following its application

This research was about the production of agri-food composts derived from coffee husk (CH) and brewers’ spent grain (BSG) in proportion 2:1 (Compost1), CH and cow manure (CM) in proportion 4:1 (Compost2), and a mixture of CH, BSG, and CM in proportion 5:3:2 (Compost3), and also determine the effects of temperature conditions on their properties. According to the results, we suggested the agri-food compost derived from coffee husk and brewers’ spent grain in warm condition. Subsequently compost was added to the wheat and Cannabis Sativa L. field and it is well-documented that the achievement of a high yield of wheat and hemp depend on retaining the nutrients in the plant root environment, which is important for intended crop production. Due to the high cost and environmental side effects of chemical fertilizer, there is a growing tendency to utilize organic fertilizer like compost in agriculture. No main effects of composts were observed for fatty acids. Soil physic-chemical features were improved by the application of composts, especially the compost derived from coffee husk and brewers’ spent grain. Moreover, this compost had positive influence on the microbial enzyme activate and biomass, probably due to the composition and higher input of carbon organic into the soil. As a result, it can be suggested to use this compost to reduce environmental pollution, improve soil fertility, and achieve high production of wheat crop.
