“…The deletion of the disorder of cultivation practices and improving aggregate stability over the chronosequence of land abandonment could also contribute to the substantial increase in SOC sequestration from AR soils during decomposition. The results of our findings are also in line with the findings of studies by Aubrey et al (2019), Dar et al (2020), and Durán Zuazo et al (2020). Their findings show that increasing the amount of C through plant residues in the soil surface will lead to an increase in the amount of CR, N, and SOC in the soil.…”

This study investigated the change in soil organic carbon (SOC), soil labile carbon (C), soil total nitrogen (N), particulate organic carbon (POC), mineralizable soil C (Min‐C) in soil aggregate fractions, and soil particles size at 0–30 cm soil depth of the semi‐steppe rangelands in Central Iran (Sheida and Khargosh regions). The study used a fully randomized design with four land uses in the rangelands including covered with rainfed wheat (CR0), abandoned rangelands (ARs) for 5–15 years (AR15), abandoned rangeland for 16–40 years (AR40), and permanently uncultivated rangelands (UR) as the reference sites that were replicated three times (n = 3) with at most 2 km distance from each other in an area of 25 ha. For each treatment, the soil samples were randomly obtained at 0–30 cm soil depth in three replicated plots of 2 × 2 m using a core size of 7 cm in diameter. The samples were mixed to take a composite soil sample (12 soil samples in each region) in June 2018. The results indicated that soil POC is the most sensitive fraction for the identification of shifts in the total SOC after the cultivation cessation because by increasing the abandoned land and the cessation of cropland activities, the POC has also increased. In conclusion, after the cessation of rainfed cropping and the recovery of natural vegetation, the increases in soil microorganism activity can result in a higher nutrient cycling in the degraded rangeland ecosystems.

“…Increased SOC, POC, POXC, and MBC stocks at both the non-calcareous and calcareous sites were due to greater residue retention under a legume-based cropping pattern, which agrees with previous research studies [57]. Low temperatures, the acidic environment, and the partially anaerobic conditions are favorable for the slower decomposition of the organic substances that were composed of a series of fractions that vary in their turnover time, decomposition degree, and recalcitrance [58]. The SOC stocks in the upper layers of the soil are more sensitive and receptive to contrasting changes in land use and management practices.…”

To evaluate the effects of conservation agriculture (CA) on SOC pools and their lability, field experiments (2015–2020) were conducted on contrasting soils under subtropical climates. The experiment on non-calcareous soils, was comprised of tillage (minimum [MT] vs. conventional [CT]) in main plots, cropping systems (Wheat [Triticum aestivum]—Aus and Aman rice [Oryza sativa L.], WRR; Lentil [Lens culinaris]—Aus and Aman rice, LRR; and Mustard [Brassica nigra]- Boro and Aman rice, MRR) in the sub-plots, and crop residue (with or without 20% residue) in the sub-sub plots. The experiment on calcareous soils, was comprised of tillage (strip-till, ST; no-till, NT; and CT) and crop residue (high residue, HR at 50% by height vs. low residue, LR at 15%). Results showed that the MT had higher SOC contents by 18.8% than the CT in non-calcareous soils. Likewise, SOC was 12.5% and 6.7% higher in the NT and ST, respectively, than in the CT in calcareous soils. Significantly higher particulate organic (POC), permanganate oxidizable (POXC), and microbial biomass carbon (MBC) were observed in the MT, NT, and ST than in the CT at both locations. Reduced tillage with residue retention under LRR had a higher SOC, including labile C pools compared to WRR and MRR systems. Similarly, carbon management index (1.2–1.5 and 1.0–1.2) in both soils had significant positive correlations with SOC lability via POXC, POC, and MBC pools, indicating a SOC sequestration potential. In conclusion, our results showed positive effects of CA on SOC and its lability across soils.

“…The Food and Agricultural Organization (FAO) indicated that due to soil degradation, only 60 harvesting years are left, which is a major concern for the growing population [18]. There is a significant reduction in soil organic carbon to 0.3 percent, and its magnitude of loss may be from 10 to 50 tons C/ha [19,20]. The soil with low soil organic carbon yields results in low agronomic yield.…”

The current biospheric emergency, fueled by climate change and habitat loss, necessitates a re-evaluation of food production systems. This chapter advocates a crucial shift to natural farming, emphasizing crop diversity and interdependence. It proposes alternatives to the food production crisis, critiquing chemical-dependent conventional farming for its adverse impacts on land, yields, and sustainability. Natural farming, characterized by minimal inputs was presented as a sustainable method. Critical challenges in contemporary agriculture, including monoculture cropping and climate change, are examined. The chapter examines the evolution of natural farming in response to crises and government initiatives, delving into traditional practices, and indigenous knowledge, and exploring traditional food and seed systems for their nutritional value. Natural farming is showcased for its positive impact on soil biodiversity and its ability to counteract land degradation. The chapter highlights Andhra Pradesh\'s community-managed Natural farming for its role in generating public debates on food systems transformation. Acknowledging the urgent need for food system transformation, the chapter concludes with a call for research partnerships to guide natural farming\'s expansion, emphasizing collaborative efforts for sustainable advancement in India\'s agricultural practices.
