Review of the relationship between soil health, climate change mitigation, and crop production when soils is enhanced with organic sources of nutrients

Abstract

When soils are not properly maintained, the agriculture sector contributes significantly to global warming by raising greenhouse gases like CO 2 and N 2 O. This review describes the relationship between organic fertilizers in improving soil health, crop production and mitigating climate change. Organic fertilizers are produced by the quick artificial decomposition from biological wastes. The synergy of using both poultry manure and nitrogen has proven to enhance the production of crops. The utilization of 4 t t ha −1 of poultry manure resulted in the most significant development and production of maize. Likewise, utilization of bio-slurry in both liquid and composted forms, either alone at a rate of 20 t ha −1 or in combination with the complete dose of chemical fertilizer at a rate of 10 t ha −1 , results in varying increases in crop yield of maize, soybean, wheat, sunflower, cotton, ground nut, cabbage, and potato compared to the control group. By utilizing organic sources of nutrients, the emissions of N 2 O can be diminished through the enhancement of nitrogen utilization effectiveness. Organic source of nutrients possesses numerous characteristics that not only enhance crop yield but also serve as options for safeguarding the environment by enhancing soil organic carbon and reducing N 2 O emission.
