“…Among them, PR is the best cropping system, supported by the highest economic, social, ecological and comprehensive benefits that it generated (Table 5), consistent with previous reports [37][38][39]. The farm gate price of potato in the winter cropping areas of Southern China was >0.3 USD/kg over the past 10 years, with an average yield of~33.5 tons/ha, while the cost of producing potatoes in the same period of time was~6900 USD/ha, generating a much higher net income in the preceding seasons than growing rice, which was estimated to be 3400 USD/ha [40].…”

Cropping systems greatly impact the productivity and resilience of agricultural ecosystems. However, we often lack an understanding of the quantitative interactions among social, economic and ecological components in each of the systems, especially with regard to crop rotation. Current production systems cannot guarantee both high profits in the short term and social and ecological benefits in the long term. This study combined statistic and economic models to evaluate the comprehensive effects of cropping systems on rice production using data collected from experimental fields between 2017 and 2018. The results showed that increasing agricultural diversity through rotations, particularly potato–rice rotation (PR), significantly increased the social, economic and ecological benefits of rice production. Yields, profits, profit margins, weighted dimensionless values of soil chemical and physical (SCP) and heavy metal (SHM) traits, benefits and externalities generated by PR and other rotations were generally higher than successive rice cropping. This suggests that agricultural diversity through rotations, particularly PR rotation, is worth implementing due to its overall benefits generated in rice production. However, due to various nutrient residues from preceding crops, fertilizer application should be rationalized to improve the resource and investment efficiency. Furthermore, we internalized the externalities (hidden ecological and social benefits/costs) generated by each of the rotation systems and proposed ways of incenting farmers to adopt crop rotation approaches for sustainable rice production.

“…Detecting the impact of management and LUC in soil carbon pools is likely to be more sensitive than total SOC (Campbell et al, 1997;Padbhushan et al, 2015;Padbhushan et al, 2016a;Padbhushan et al, 2016b;Rakshit et al, 2018;Meetei et al, 2020;Padbhushan et al, 2020). Soil microbial activity is the central process in the terrestrial carbon cycle.…”

Land-use changes (LUC), primarily due to deforestation and soil disturbance, are one of the major causes of soil quality degradation and greenhouse gas emissions. Effects of LUC on soil physicochemical properties and changes in soil quality and land use management strategies that can effectively restore soil carbon and microbial biomass levels have been reported from all over the world, but the impact analysis of such practices in the Indian context is limited. In this study, over 1,786 paired datasets (for meta-analysis) on land uses (LUs) were collected from Indian literature (1990–2019) to determine the magnitude of the influence of LUC on soil carbon, microbial biomass, and other physical and chemical properties at three soil depths. Meta-analysis results showed that grasslands (36.1%) lost the most soil organic carbon (SOC) compared to native forest lands, followed by plantation lands (35.5%), cultivated lands (31.1%), barren lands (27.3%), and horticulture lands (11.5%). Our findings also revealed that, when compared to forest land, the microbial quotient was lower in other LUs. Due to the depletion of SOC stock, carbon dioxide equivalent (CO2 eq) emissions were significantly higher in all LUs than in forest land. Results also showed that due to the conversion of forest land to cultivated land, total carbon, labile carbon, non-labile carbon, microbial biomass carbon, and SOC stocks were lost by 21%, 25%, 32%, 26%, and 41.2%, respectively. Changes in soil carbon pools and properties were more pronounced in surface (0–15 cm) soils than in subsurface soils (15–30 cm and 30–45 cm). Restoration of the SOC stocks from different LUs ranged from a minimum of 2% (grasslands) to a maximum of 48% (plantation lands). Overall, this study showed that soil carbon pools decreased as LUC transitioned from native forestland to other LUs, and it is suggested that adopting crop-production systems that can reduce CO2 emissions from the intensive LUs such as the ones evaluated here could contribute to improvements in soil quality and mitigation of climate change impacts, particularly under Indian agro-climatic conditions.

“…While studying the interaction effect of land uses and soil depth on SOC content, it was observed that the highest SOC content [5.72 g kg -1 ] was recorded at the surface 0-20 cm soil depth of the forest land and the lowest [1.83 g kg -1 ] was obtained at 40-60 cm soil depth of the orchard land which was, however, statistically at par with 40-60 cm depth of fallow land, cultivated rice-potato land, cultivated rice land and pasture land; at par with 20-40 cm depth of fallow land, cultivated rice land, pasture land and orchard land as presented in Table 3. [14] , however, reported that SOC of surface soil was significantly and positively correlated with available N, available P2O5 and clay content and significantly and negatively correlated with bulk density. Similar significant positive correlation of SOC with available K2O was reported by Bertol et al (2017) [1] and that of SOC with available S was reported by Neptune et al (1974) [17] .…”

“…Soil has the capacity to store C two times more than atmosphere (Davidson et al, 2000) [7] . Variations in land uses and their management can influence the soil fertility by altering the content of SOC along soil depths (Meetei et al, 2020) [14] . Therefore, studies on SOC content with respect to land uses and soil depth is very essential for sustainable soil management.…”

Soil organic carbon (SOC) is the key indicator of soil quality and overall sustainability of the environment. Information of OC in soil is very important as it influences chemical, physical and biological soil properties. In order to assess the difference in SOC content along depth and land uses and relationship of SOC with soil properties, a total of 54 soil samples were collected from 3 soil depths and 6 land uses of lateritic soil of Birbhum district of West Bengal. The soil physical properties like bulk density, particle density, sand, silt and clay content; chemical properties like pH, EC, OC, available N, P2O5, K2O, S were estimated following standard procedure. Results exhibited significant variation of SOC with soil depths and land uses. There was decrease in SOC value with increase in soil depth for all studied land uses. The SOC value was highest and lowest forest and fallow land respectively for all the soil depths. Unrelatedly of soil depths, forest land and fallow land recorded highest and lowest SOC respectively. But, unrelatedly of land uses, 0-20 cm and 40-60 cm soil depth noted highest and lowest SOC respectively. The value of SOC due to combined effect of depth and land uses was noted highest and lowest in 0-20 cm depth of forest and 40-60 cm depth of orchard land respectively. The soil pH, BD, sand and silt content exhibited significant negative correlation with SOC and available K2O and S and clay disclosed significantly positive correlation with SOC.
