Intensive tillage coupled with crop residue burning and conventional agronomic practices in
sugarcane (Saccharum officinarum L.) cropping system is a serious issue causing soil
degradation and environmental pollution. Globally the principles of minimum soil
disturbance, crop residue management and suitable nutrient management practices have
emerged as alternative strategies for enriching the soil resource base (Jat et al., 2019). For a
sustainable agricultural production system, soil organic carbon and soil biology is vital as
they regulate all the other chemical, physical and biological properties (Parihar et al., 2018).
A number of research studies have reported the potential of these strategies to serve many
ecosystem functions such as enhanced soil enzymatic activity, microbial count, carbon
sequestration, increased resource use efficiency, making the system resilient towards extreme
climate events and climate change mitigation (Choudhary et al., 2018; Datta et al., 2019; Jat
et al., 2019). However, benefits of these strategies are needed to be effectively reaped in
sugarcane production system that occupies 5 million ha acreage and utilizes more than 5% of
country’s irrigation resources on merely 2.6% of the net cultivated area and produces 108
million tonnes of crop residues, annually. In sugarcane-based cropping system, trash burning
