Organic Carbon Stock

The changes in the pattern of land use and land cover (LU/LC) have remarkable consequences on ecosystem functioning and natural resources dynamics. The present study analyzes the spatial pattern of LU/LC change detection along the Killiar River Basin (KRB), a major tributary of Karamana river in Thiruvananthapuram district, Kerala (India), over a period of 64 years (1957-2021) through Remote Sensing and GIS approach. The rationale of the study is to identify and classify LU/LC changes in KRB using the Survey of India (SOI) toposheet (1:50,000) of 1957, LISS-III imagery of 2005, Landsat 8 OLI & TIRS imagery of 2021 and further to scrutinize the impact of LU/LC conversion on Soil Organic Carbon stock in the study area. Five major LU/LC classes, viz., agriculture land, built-up, forest, wasteland and water bodies were characterized from available data. Within the study period, built-up area and wastelands showed a substantial increase of 51.51% and 15.67% respectively. Thus, the general trend followed is the increase in built-up and wastelands area which results in the decrease of all other LU/LC classes. Based on IPCC guidelines, total soil organic carbon (SOC) stock of different land-use types was estimated and was 1292.72 Mt C in 1957, 562.65 Mt C in 2005 and it reduced to 152.86 Mt C in 2021. This decrease is mainly due to various anthropogenic activities, mainly built-up activities. This conversion for built-up is at par with the rising population, and over-exploitation of natural and agricultural resources is increasing every year.

Organic Carbon Stock

It has been demonstrated that the high bulk densities of clayey subsoils of Sodosols can result from a process involving shrink/swell cycles and the development of ped coatings containing topsoil material. Our objective was to study this process according to land use and to compute the amount of organic carbon introduced into the subsoil as a consequence of ped coating in the subsoil. In an area located east of Katanning, we carried out an intensive soil survey and selected 2 closely adjacent sites with similar soils but differing in their land use: a cultivated soil and a never cultivated soil in an undisturbed strip of land. Pit faces and horizontal planes of the top of the subsoil were studied. The polygonal network corresponding to the cross-section of the prismatic peds was described. The clay content and bulk density of the prisms was determined. The carbon contents of the coatings and of the sandy material rich in organic carbon that corresponded to remnants of native vegetation was measured. Results showed that the coating process has occurred under native vegetation but is more active when the land has been used for agricultural and pastoral activities, as indicated by thicker sandy-clay coatings on the vertical faces of prisms and the higher bulk densities in the subsoil. The mean bulk density was 1.71 g/cm3 at 20-25 cm depth at the undisturbed site and was 1.86 and 1.82 g/cm3 at 20-25 and 25-30 cm depth, respectively, at the cultivated site. The total soil organic carbon stock was estimated to be close to 68.9 and 61.0 Mg/ha at the undisturbed and cultivated sites, respectively. The organic carbon stock in the subsoil was 38.5 and 23.3% of the respective total stocks. One fourth of the carbon stock in the subsoil corresponded to materials rich in organic carbon that originated from roots of native vegetation. The organic carbon stock in the ped coatings was <1% of the total stock at the 2 sites. Finally, our results support the adoption of zero-till agricultural system for the soil studied to restrict subsoil densification.

One Way Anova

A study was undertaken in Haryana to estimate Soil organic carbon stock under different orchards available there under horticulture land uses which covered 47,036 ha area in Haryana. Maximum organic carbon stock was observed under Mango (36.24 t ha-1) followed by Nebu (35.85 t ha-1), Ber (30.37 t ha-1), Guava (29.45 t ha-1), Kinnu (25.11 t ha-1), Aonla (24.67 t ha-1), Malta (24.20 t ha-1) and the least was under the combination of Aonla + Anar (14.97 t ha-1). When SOC stock under different horticulture species was tested by one - way ANOVA, it was found that SOC stock under different species was significantly different (Variance ratio, F = 4.086; p = < 0.05). SOC stock under Mango was significantly different from the SOC stock under all other species except Nebu, Malta and Grapes. Mitigation potential indicates that soils under Mango and Nebu can sequester nearly two and half times more SOC as compared to that in Aonla + Anar orchard, while the soils under Ber and Guava and Kinnu can sequester nearly double the amount of SOC stock in comparison to Aonla+ Anar orchard. Over all, in Haryana the soils under horticulture land use have 1.37 million tones of SOC stock which is equivalent to 5.05 million tons of CO2.
