Soil is a living and dynamic body, which is prone to degradation under conventional agricultural practices. Healthy soil is one of the most important pillars of sustainability as it delivers several ecosystem services along with its control on microbial activity, nutrient recycling, and decomposition. Nature‐based solutions can play an important role in restoring soil quality for enhanced agricultural productivity and sustainability. This article discusses various nature‐based options available for improving soil quality. Indigenous practices such as sheep penning, tank silt application, green manuring, and refuse from croplands and households have the potential to restore and maintain soil fertility. Biofertilizers can add nutrients (N fixers), fixe up to 300 kg N ha through biological nitrogen fixation (BNF) and facilitate (nutrient solubilizer and mobilizers) nutrient availability in the soil. Biochar, a commonly used product, can increase soil moisture availability by 8%–10% and aids in mitigating climate change through C‐sequestration. Biochar may have a climate change mitigation potential of 1.8 Pg CO2‐C equivalent per year. When added to the soil, it not only acts as a nutrient source; but also acts as a soil amendment. Biogas slurry, the effluent from biogas reactors, contains various nutrient elements that can enrich soil fertility. The holistic approach in a farming system, through integration of different enterprises, reduces dependence on off‐farm resources. Soil management through nature‐based options will maintain crop productivity and sustainability in the long run without any adverse effects on the environment. [ABSTRACT FROM AUTHOR] |
