“…Therefore, restoration of carbon in the soil can be one of the options to counteract the effect of climate change and the problems created due to climate change. Since OM plays a multifaceted role in several soil processes (Gregorich et al, 1994), SOC is one of the essential components for sustaining soil health and food security by the maintenance of the production system (Anantha et al, 2018).…”

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.

“…For example, the OC derived from roots and stubble is sequestered more efficiently than that derived from crop straw return (Li et al 2016;Kong et al 2005;Halvorson et al 2016). The reason for this difference can be attributed to the following: the OC derived from roots and rhizodeposition may have a greater chance to access and interact with soil particles; in addition, this carbon is both physically and chemically protected and may be retained in soil more efficiently (Kong et al 2005;Mandal et al 2008;Anantha et al 2018). These factors may, to some extent, help explain why the highest CSE values were observed in treatments receiving no or unbalanced fertilization, where more carbon was available from the root debris relative to that in the balanced fertilizations, because the absence of plant nutrients may induce root growth and lead to a higher root-to-shoot ratio.…”

It is important to understand soil organic carbon (SOC) sequestration and its relationship with crop productivity. Based on two long-term experiments under irrigated vs rain-fed conditions conducted in the China Loess Plateau, we evaluated SOC sequestration efficiency under diverse fertilization regimes and quantified the relationship between crop yield and SOC. The experiments consisted of a winter wheat-summer maize system under irrigated conditions with nine treatments-nitrogen (N), N and phosphorus (P), N and potassium (K), P and K (PK), combined NPK, crop straw (S) in combination with NPK (SNPK) and dairy manure (M) integrated with NPK (M1NPK and M2NPK)-and a winter wheat-summer fallow system under rain-fed conditions with seven treatments-CK, N, NK, PK, NP, NPK, and MNPK. After 25 years, the SOC storage was generally higher in the irrigated plots than in the rain-fed plots by 6% on average. The carbon sequestration efficiency was higher under the rain-fed (28%) than under the irrigated (19%) condition. The relationship between relative yield and SOC content suggested that the threshold SOC contents for obtaining the highest crop yield were 10.0 and 8.8 g kg −1 for the winter wheat-summer maize and winter wheat-summer fallow cropping systems, respectively. This difference suggests that a higher SOC level is required to support high crop productivity in the irrigated system than in the rain-fed system.

“…Human led LUC can result into significant exchanges of CO 2 between the soil and air (Lal, 2000).Therefore, restoration of C in the soil can only be option to counteract the effect of climate change and the problems created due to climate change. Since OM plays a multifaceted role in several soil processes (Gregorich et al ., 1994) hence, SOC is the panacea for sustaining soil health and food security by the maintenance of production system (Anantha et al ., 2018).…”

Several studies on carbon status have considered current land management practices and land use systems. There however is a need for meta-analysis study to understand the status of carbon over long periods and ways to boost its storage in soils the current scenario to ensure sustainability for securing food by improving soil health. In this context over 1786 pairs dataset from several studies were generated during period 1990-2019 had been collected from Indian experiments. The review shows that carbon status has negative effect on land uses (barren land, cultivated land, grassland, horticultural land and plantation land) over the forest land. The other land uses can be carbon equivalent to forest land by regaining the carbon stocks by 34, 41, 2, 34 and 48%, respectively. If this can become possible through management practices, a large amount of atmospheric carbon dioxide can be restored in the soil and problems of climate change can be mitigated. Also, this paper is synthesized to characterize the human interventions for their effects to sequester carbon in cultivated soils. Integration of organics with chemical fertilizer in cultivated soil can be one of the better land use management strategies for restoring carbon in the soil. The effect of carbon and yield was significantly increased in integrated nutrient management by 23.2% and 1.2% (in rice) and 16.2% and 4.5% (in wheat), respectively in comparison to inorganic alone. Therefore, meta-analysis of these data sets provides information that may help the scientific community to strategically guide and plan future development initiatives.
