“…Similarly, de Santiago et al [74] reported more Cu, Mn, and Zn concentration under conservation tillage, which is associated with higher SOM and higher microbial activity under less soil disturbance than that of conventional tillage at 0 to 5 cm soil-depth after 21 years of the long term experiment. In the present study, more residues were left in the SC 5 scenario with least soil disturbance resulting from higher Cu, Mn, and Zn availability on the top surface and it decreased with an increase in soil depth, which restricts the movement in the soil due to complexation of Cu, Mn, and Zn with the chelated agents [75]. The Fe (Figure 3) was significantly higher in residue returning practices (SC 4 ) than other scenarios while conservation tillage showed minimum concentration of Fe (Figure 3), probably due to conditions that favor more available Fe 2+ than Fe 3+ fractions [47].…”

In South Asia, soil health degradation is affecting the sustainability of the rice-wheat cropping system (RWCS). Indeed, for the sustainability of the soil quality, new adaptive technologies, i.e., conservation tillage and straw management resource conservation, are promising options. This investigation was focused on the interaction of tillage and straw management practices and their effects on Aridisols, Yermosols soil quality, and nutrients dynamics with different soil profiles within RWCS. The long-term field experiment was started in 2014 with the scenarios (i) conventional tillage (SC1), (ii) residue incorporation (SC2), (iii) straw management practices (SC3 and SC4) and conservation tillage (SC5). Conservation tillage practice (SC5) showed significant impact on properties of soil and availability of nutrients in comparison with that of conventional farmers practice (SC1) at the studied soil depths. The SC5 showed significant results of gravitational water contents (25.34%), moderate pH (7.4), soil organic-matter (7.6 g kg−1), total nitrogen (0.38 g kg−1), available phosphate (7.4 mg kg−1), available potassium (208 mg kg−1) compared to SC1 treatment at 0 to 15 cm soil depth. Whereas, DTPA-extractable-Cu, Mn, and Zn concentration were significantly higher, i.e., 1.12 mg kg−1, 2.14 mg kg−1, and 4.35 mg kg−1, respectively under SC5 than conventional farmer’s practices, while DTPA (diethylene triamine pentaacetic acid) extractable Fe (6.15 mg kg−1) was more in straw management practices (SC4) than conventional and conservation tillage. Therefore, conservation tillage (SC5) can surge the sustainability of the region by improving soil assets and nutrients accessibility and has the potential to minimize inorganic fertilizers input in the long run.
