“…A number of SOC models have been developed, but applying these models requires adequate evaluation with measured SOC trends from experimental for different environmental conditions and management practices [15] . For example, the CENTURY model [16] has been widely used to simulate SOC changes under different management conditions in long-term experiments (e.g., [17] , [18] and [19] ). With the development of CENTURY, the model has been successfully employed in long-term fertilizer, irrigation, pest management, and site-specific farming applications [20] , [21] .…”

Soil organic matter models are widely used to study soil organic carbon (SOC) dynamics. Here, we used the CENTURY model to simulate SOC in wheat-corn cropping systems at three long-term fertilization trials. Our study indicates that CENTURY can simulate fertilization effects on SOC dynamics under different climate and soil conditions. The normalized root mean square error is less than 15% for all the treatments. Soil carbon presents various changes under different fertilization management. Treatment with straw return would enhance SOC to a relatively stable level whereas chemical fertilization affects SOC differently across the three sites. After running CENTURY over the period of 1990–2050, the SOC levels are predicted to increase from 31.8 to 52.1 Mg ha−1 across the three sites. We estimate that the carbon sequestration potential between 1990 and 2050 would be 9.4–35.7 Mg ha−1 under the current high manure application at the three sites. Analysis of SOC in each carbon pool indicates that long-term fertilization enhances the slow pool proportion but decreases the passive pool proportion. Model results suggest that change in the slow carbon pool is the major driver of the overall trends in SOC stocks under long-term fertilization.

“…We have been working on different models for predicting crop performance, soil quality and health (Bhattacharyya et al 2010(Bhattacharyya et al b, 2011(Bhattacharyya et al , 2013(Bhattacharyya et al , 2007Telpande et al 2013;Ray et al 2014;Chatterjee et al 2014); also trying to visualize the future soils in the event of climate change and global warming (Bhattacharyya 2022c, Bhattacharyya et al 2012, 2008 . Dear friends, all such efforts should culminate in developing a model understanding of using artificial intelligence (AI) in agriculture, natural resource management, and ecosystem functions to benefit human civilization for the next generations.…”

On 2022 World Soil Day (WSD), the author shares his experiences in soil surveys since his early days till date. Soil is the beginning of food, as mentioned in the year 2022 theme for WSD. Soil survey is the beginning of soil research regarding pedology, edaphology, and soil biology. The author delves into his experiences from different states, villages, and landscapes to identify varied soils. He argues about the grouping of soils and their utility in edaphology. Fieldwork, laboratory work, data generation, and dissemination are all critical; soil survey is the foundation of all such research activities. Fieldwork is strenuous, but in the long run, it's rewarding. The tour diary of the author describes the formation of spatially-associated Vertisols, Alfisols and Mollisols; besides, mention of Mollisols (brown forest soils) has been made the Histosols and their considerable capacity to be the hub of organic carbon which could be utilised as a model to combat climate change and global warming using artificial intelligence (AI). This soil database may serve as an essential engine for a negative emission strategy to combat global warming and assist land degradation neutrality (LDN). Starting his career in the Western Ghats, journeying through the tortuous paths of many terrains in the Satpura, Vindhyan, Himalayas, Northeastern regions and the southern Peninsula, the author returns to the same place at the end of his career, in the Western Ghats. He busy in research and continuing has been his quest for science.

“…Despite the importance of tropical areas in terms of the percentage of global SOC stocks, research on the effect of LULC on SOC stock and C sequestration is limited in these regions. SOC stock has been measured for different agroecological regions in India (Bhattacharyya et al 2000;Bhattacharyya et al 2008) but assessment of SOC stock and its variation under different LULC or due to LULC change have been confined to the Indo-Gangetic Plain and Himalayan and Black Soil regions (Bhattacharyya et al 2007b;Bhattacharyya et al 2009a;Bhattacharyya et al 2010). Information on similar aspects is lacking in most parts of the Peninsular Plateau which, owing to its low SOC stock, have a good potential of sequestering C with proper land management practices.…”

Conversion of forest area to agricultural land use led to an estimated loss of 36 Pg carbon (C) from soils between 1860 and 1960. Soil organic carbon (SOC) loss through cultivation can, however, be reduced and potentially fixed in soil through proper soil and land management. The objective of this study was, therefore, to determine the effect of crop cultivation vis-à-vis forest and plantation, on the SOC concentration, especially in SOC-poor plough layer, in Irga watershed Dhanwar (Typic Haplustalfs) and Birni (Typic Paleustalfs) soils predominate in the two administrative blocks within the watershed –, respectively. Three plots were chosen for each soil subgroup to represent three predominant land cover conditions viz. forest, plantation and mono-cropped area in Dhanwar and Birni. In general SOC stock was high in the mango orchard in Dhanwar (226 Mg C ha-1) and cultivated land in Birni (242 Mg C ha-1) and least in the plot under Eucalyptus plantation in Birni. In the 0-20 cm depth, mango orchard in Dhanwar and cultivated land in both the sites showed an increase in SOC pool in comparison to forests; (Eucalyptus plantation). The practice of paddy-fallow rotation and the application of animal manure led to an increase in the SOC pool in the plough layer of agricultural soils in the SOC-poor area; and thus have the potential to sequester C in the Irga watershed.
