“…not adopted to add mineral fertilizers and organic matter on a continuing basis (Figures 10 a). Modelling and results from the long-term experiments predict that soil organic carbon can be increased if recommended dose of fertilizers (RDFs) along with farm yard manure (FYM) (10 t ha -1 ) are applied 35,37,38,41 . For Patancheru soils, BAU indicates an increase of SOC as the site is pristine.…”

“…Use of pedotransfer functions helps in this regard as has already been demonstrated while developing soil information system for the Indo-Gangetic plains and the black soil regions of India 34 . Such exercise not only helps monitoring soil parameters, but also permits the trend of changes in the dynamic properties of soils through appropriate data interpretation 36 , soil carbon and crop modelling 35,37,38 .

“…We made an effort to understand the nature of the SAT soils as it would exist in years to come. Judging by the rate of changes in chemical and physical soil parameters (Table 9) and also on the basis of available trend of data in the semi-arid tropics 27,35,[37][38][39] , we attempted to project changes in soil properties in case the present land use and management interventions are continued (business as usual, BAU) and also, if appropriate, management interventions are adopted 40 ( Figure 10). It is quite likely that soil organic C level in black soils will further decrease until management interventions are CURRENT SCIENCE, VOL.…”

Associated red and black soils are common in the Deccan plateau and the Indian peninsula. The red soils are formed due to the progressive landscape reduction process and black soils due to the aggradation processes; and they are often spatially associated maintaining their typical characteristics over the years. These soils are subject to changes due to age-long management practices and the other factors like climate change. To maintain soil quality, it is essential to monitor changes in soil properties preferably using benchmark (BM) soil sites. One such example lies at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) farm in Patancheru, India where red (Patancheru) and black (Kasireddipalli) soils co-exist in close association under almost similar topographical condition, which also represents very commonly occurring spatially associated soils. The database generated over the years for these two dominant soils that are under cultural practices for the last 2-3 decades, helps us understand the relative changes in properties over a time scale. To do this exercise, we revisited the BM spots as the data on the original characterization of these soils since the development of the farm, are available, for comparative evaluation. We also attempted to make prediction of future changes in properties for these two important and representative black and red soils of the ICRISAT farm in Patancheru, India.

This could be achieved through the addition of farm yard manure (FYM) or other green manures (Bhattacharyya et al, 2011), which could potentially increase the present QEV from 0.44 to 0.51% in soils of agricultural system to the 0.70 to 0.80% observed in the soils of horticultural and forest systems in the subhumid tropical climate of India.…”

Soil organic carbon (SOC) is the major determinant of soil quality, and it greatly influences global carbon cycling and climate change. This paper is a synthesis of the literature on soil carbon research in India, including soil organic and inorganic carbon stocks, in the form of thematic maps for national and regional level planning at bioclimatic systems and agroecological subregion levels in the country. The potential role of soils in mitigating the global warming effects of atmospheric CO2 is discussed using results from Indian tropical soils. The database on Indian soils collected through natural resource inventory and soil carbon and crop modeling approaches show that sequestration of atmospheric CO2 occurs as pedogenic carbonates and plays role as a soil modifier in enhancing soil organic carbon in the drier parts of the country through management interventions. Clearly, soils can act as a potential medium for sequestering atmospheric CO2 to mitigate the global warming effect.

“…As one of the most classic and widely used soil C turnover models, the RothC model (Jenkinson et al, 1990), however, requires only a few easily obtainable parameters and input data. The model has been widely and frequently adopted to simulate the soil C changes under different management treatments and soil and climate conditions across the world's cropping systems (Falloon and Smith, 2002;Guo et al, 2007;Yang et al, 2003;Bhattacharyya et al, 2011;Skjemstad et al, 2004;Smith et al, 2005). More recently, by adopting the model's original default parameters, the RothC model has been tested against the measurements obtained from 16 long-term experimental sites across the global croplands and showed a generally good performance in representing the SOC dynamics under different treatments at different sites (Wang et al, 2016).…”

Abstract. Changes in the soil organic carbon (SOC) stock are determined by the balance between the carbon input from organic materials and the output from the decomposition of soil C. The fate of SOC in cropland soils plays a significant role in both sustainable agricultural production and climate change mitigation. The spatiotemporal changes of soil organic carbon in croplands in response to different carbon (C) input management and environmental conditions across the main global cereal systems were studied using a modeling approach. We also identified the key variables that drive SOC changes at a high spatial resolution (0.1 • × 0.1 • ) and over a long timescale (54 years from 1961 to 2014). A widely used soil C turnover model (RothC) and state-of-the-art databases of soil and climate variables were used in the present study. The model simulations suggested that, on a global average, the cropland SOC density increased at annual rates of 0.22, 0.45 and 0.69 Mg C ha −1 yr −1 under crop residue retention rates of 30, 60 and 90 %, respectively. Increasing the quantity of C input could enhance soil C sequestration or reduce the rate of soil C loss, depending largely on the local soil and climate conditions. Spatially, under a specific crop residue retention rate, relatively higher soil C sinks were found across the central parts of the USA, western Europe, and the northern regions of China. Relatively smaller soil C sinks occurred in the high-latitude regions of both the Northern and Southern hemispheres, and SOC decreased across the equatorial zones of Asia, Africa and America. We found that SOC change was significantly influenced by the crop residue retention rate (linearly positive) and the edaphic variable of initial SOC content (linearly negative). Temperature had weak negative effects, and precipitation had significantly negative impacts on SOC changes. The results can help guide carbon input management practices to effectively mitigate climate change through soil C sequestration in croplands on a global scale.
