“…Addition of organic matter in the form of cow dung (40 kg/tree) and the return of plant litter to the soil provide additional stable organic carbon. This is consistent with land management research according to (Ermadani et al, 2018) where the addition of organic material in the form of litter plants can supply humic acid (AH) of 0.56%.…”

“…The decrease in organic-C content in the soil can be caused by changes in management and land use so that the availability of stable carbon will be reduced (Ermadani et al, 2018). The organic-C content will undoubtedly determine the amount of humic acid that will form in the soil.…”

“…This is closely related to the overhaul of organic material. Management of organic-C in the soil, especially in tropical climate regions, is difficult due to the rapid rate of organic decomposition (Ermadani et al, 2018). Addition of organic matter in the form of cow dung (40 kg/tree) and the return of plant litter to the soil provide additional stable organic carbon.…”

Changes in land use will impact on the characteristics of humic acid in the soil due to biotic and abiotic factors. The study aimed to characterize humic acid in soil from various land uses in Tutur District, Pasuruan Regency of East Java. Soil sampling was carried out on six land uses, namely mixed garden, coffee plantation, apple orchard, vegetable garden, pine forest, and conservation forest. Analysis of soil samples included soil chemical characteristics (pH, redox, organic-C, and total-N) and characterization of humic acid included colour ratio of E4/E6, total acidity, carboxyl groups, and phenolic groups. The results showed that the land use of coffee plantation provided the best soil fertility indicated by the contents of humic acid, total-N, organic-C in the soil that were higher than that of other land-uses. The highest humification index was obtained for coffee plantation land use with the measurement of the E4/E6 colour ratio of 4.56 index value. The best characteristics based on the total value of acidity, the -COOH group and the phenolic -OH group were observed in the coffee plantation. This was supported by the characteristic of humic acid through the humification index or E4/E6 colour ratio, as well as the low phenolic -OH value which is a characteristic of fulvic acid.

“…Fraksi C organik tanah labil seperti C organik partikulat sangat sensitif terhadap perubahan penggunaan lahan dan merupakan indikator yang paling peka terhadap kualitas tanah. Sedangkan fraksi C organik stabil lebih resisten terhadap perubahan penggunaan lahan dan dapat digunakan sebagai indikator untuk menilai kapasitas tanah dalam menyimpan karbon (Ermadani et al, 2018).…”

The content of soil C-organic is strongly influenced by land management. Plants tend to increase soil organic C-stock, however an increase in soil temperature can increase the rate of decomposition of soil organic matter which will reduce soil organic C-stock. The aim of the study is to look at the relationship of soil organic carbon stock (SOCS) with changes in soil surface temperature. The study was conducted using a survey method consisting of 5 stages, namely preparation, pre-survey, main survey, soil analysis in the laboratory and data processing. Soil sampling is done by purposive random sampling under several land units (LU). LU is limited by the order of the soil, slope, and land use. Based on the land unit map, we found 14 land units in the study area. Soil samples were taken at a depth of 0-20 cm. Surface temperature measurements are carried out directly in the field using a room temperature thermometer. The parameters analyzed are organic-C, organic particulate-C, and bulk density (BD). The research data were processed statistically using simple linear regression equations. The results showed that the measurement of rice field surface temperature had the highest temperature of 34 0C, and rubber plantations had the lowest temperature of 28 0C. Organic-C affects soil BD, the higher the value of organic-C, the lower the BD value. The highest carbon stock was found in soil unit 10 with rubber plantations with a slope of 8-15%, 41 kg m-2 and decreased with increasing slope. The difference in the value of SOCS in rice fields is influenced by land management, because there is no return of crops residue in the form of straw to the ground. The results of the regression analysis showed that surface temperature did not have a significant effect on the SOCS value.Keywords : carbon stock, land use, Padang Laweh

“…Therefore, it is important to maintain C content in soil for avoiding degradation and implementing sustainable productivity management (Lal 2014 There is widespread agreement that agricultural practices diminish the amount SOC stored in soil [20]. Accordingly, SOM continuous decline without optimum management ultimately causes land degradation [21]. Hence, SOM management is important to many soil properties related to ecosystem function and plant growth (Powlson et al2011).…”

Present study was conducted in the Department of Soil Science JNKVV, Jabalpur during 2018-2020. GPS based 531 soil samples were collected from each domain viz., Bhopal, Jabalpur, Vidisha and Hoshangabad of 10.1 Agro ecological sub region (AESR). The samples analyzed for soil organic carbon (SOC) and calcium carbonate (CaCO3) then soil organic carbon density (SOCD), total organic carbon density (TOCD), soil inorganic carbon density (SICD) and total carbon density (TCD) in Mg C ha-1 were calculated. The results of SOCD, TOCD, SICD and TCD ranged from 4.73 to 25.12, 9.22 to 48.98, 1.00 to 21.29 and 11.08 to 68.80 Mg C ha-1 with mean value of 12.19, 23.78, 7.58 and 31.36 Mg C ha-1 in AESR 10.1 and Coefficient of variation (CV) 37.58, 37.58, 50.88 and 31.24 %. The overall trend in SOCD was Bhopal > Vidisha > Jabalpur > Hoshanagabad and SICD was Vidisha > Hoshanagabad > Jabalpur >Bhopal while TCD was in trend of Bhopal > Vidisha > Hoshangabad> Jabalpur. Geo-statistical indicated that Ordinary Kriging used and all variogram were in isotropic form. In Bhopal domain, Gaussian model best fitted for of SOCD, TOCD, and TCD but spherical model for SICD. In Jabalpur domain, exponential domain best fitted for TCD and TOCD but for SICD, spherical model and for SOCD, Gaussian model is best fitted. In Vidisha domain, exponential model best fitted for all. In Hoshangabad domain, exponential model is best fitted for SOCD and TOCD and Gaussian and J-Bessel model best fitted for TCD and SIC, respectively. The nugget/ sill (N/S) ratio was <25% which exhibit strong SD only for SICD in Bhopal domain. The N/S ratio was found to be >25% but <75% which showed moderate SD, for SOCD, TOCD and TC, TOCD, SICD and TCD; SOCD, TOCD, SICD and TCD and SOCD, TOCD, SICD and TCD in Bhopal, Jabalpur, Vidisha and Hoshangabad domain, respectively. The correlation range (m) for SOCD, TOCD, SICD and TCD are 5448.413, 4809.535, 360.522, and 5113.050; 7201.044, 6601.044, 611.651, and 8438.711; 5734.559, 7334.398, 1323.773, and 7881.289 and 5418.684, 5433.206, 8887.656, and 1836.274 in Bhopal, Jabalpur, Vidisha and Hoshangabad domain, respectively. The carbon density was found in order of Jabalpur> Hoshangabad >Vidisha > Bhopal.
