“…Zhang et al, 2013) who evidenced high soil carbon stock in bamboo forest as compared to native forest, evergreen forest and paddy fields, respectively. The result is in contrary of (Kenye et al 2019) that bamboo has low SOC stock as compared to homegarden, grassland, natural forest and shifting cultivation. This can be explained by the legacy effects of the land use history, climate and types of bamboo species used in the studies are different.…”

In Ethiopia, bamboo thickets and woodlands play an important role in soil-water conservation and climate change mitigation in arid and semi-arid regions. However, bamboo mass flower-ing, rapid demographic changes and expansion of agricultural investments to bamboo domi-nated areas have led to deforestation and land degradation. In this study, we determined the effects of deforestation and subsequent cultivation on soil physical and chemical properties along a chronosequence of closely located agricultural lands with different ages (1, 3, 5 and 7 years) since converted from natural lowland bamboo forest. Hence, soil samples (n = 90) have been taken from both natural bamboo forests and adjacent agricultural lands at two soil depths (0-20 cm and 20-40 cm). Our result showed that CEC, K+, Ca+, Mg+ and available P were varied significantly with respect to cultivation periods and soil depth, while soil pH and Na+ varied with soil depth (P < 0.001). Soil C and total N contents (g/kg) in 0-20 cm soil layer declined significantly and exponentially with increasing years under cultivation. Conversion of natural bamboo forest to cropland during the past seven-year period significantly increased soil pH with soil depths, while CEC was declined throughout the cultivation period and soil depth. In general, the result revealed that conversion of natural lowland bamboo and subsequent cultivation of soil had negative effects on measured soil physicochemical properties.

“…In forest land use, the SOC stock varied from 73.0 Mg ha -1 at 0-30cm depth to 52.5 Mg ha -1 at 80-100 m depth in macro-sized fraction. In plantations the SOC stock varied from 26.4 Mg ha -1 at 0-30cm depth to 15.8 Mg ha -1 at 80-100 m whereas, in agro-forestry land use the SOC stock varied from 30.1 Mg ha -1 at 0-30cm depth to 24.7 Mg ha -1 at 80-100 m. Kenye et al (2019) also reported that natural forest recorded the highest mean SOC concentration with 2.74% at 0-45cm depth and lowest in the bamboo plantation (1.09%) in land uses of Mizoram. Comparison of SOC in the forest and agriculture land gives an understanding of the management effect on SOC stock.…”

“…The data generated in the study will be beneficial to the user groups viz., farmers in identifying the most suitable land use for enhancing the storage of soil organic carbon thereby improving yields of crops and trees. also improving the quality of soil (Kenye et al, 2019). There exists considerable spatial variability according to land uses and soil depths in SOC content.…”

Soil organic carbon (SOC) plays a vital role in soil fertility and is important for its contributions to mitigation and adaptation to climate change. The present study was undertaken to estimate the SOC stock in soils under different land uses of Cauvery Delta zone of Tamil Nadu. Four different land uses were selected for the study viz, Forests, Agriculture, Agro-forestry and Plantations. Soil samples were collected from Madukkur and Kalathur soil series of Cauvery Delta zone for soil carbon analysis. The soil samples were fractionated into three aggregate size classes viz., macro-aggregates (250-2000µm), micro-aggregates (53-250 µm) and silt and clay sized fraction (<53 µm). At 0-30 cm depth, the forest land use stored the maximum SOC stock in the different size fractions viz. macro-sized fraction (73.0 Mg ha-1), a micro-sized fraction (76.0 Mg ha-1) and silt+clay sized fraction (77.0 Mg ha-1) in Madukkur series. Agriculture land use registered the lowest SOC stock. Among the different size fractions, silt+clay sized fraction (< 53 µm) retained the maximum SOC in all the land uses. In Kalathur series also, maximum soil organic carbon stock was recorded in forest land use. The data generated in the study will be beneficial to the user groups viz., farmers in identifying the most suitable land use for enhancing the storage of soil organic carbon thereby improving yields of crops and trees.

“…There are many reports on soil available carbon under different land uses and according to the report of Choudhury et al (2013) North-east India showed the highest SOC stock in dense forest (140.4 Tg) and least in shifting cultivation (10.7 Tg) with total SOC stock of 339.82 Tg, irrespective of land use system. Similarly, a study from Mizoram (Kenye et al 2019) showed that under shifting cultivation soil carbon stock decreased to maximum even more than paddy field. All these studies have carried out detail study of carbon stock and its spatial distribution under different land use systems.…”

“…According to the Kyoto Protocol, soils of both forest and agriculture may be considered as carbon sink, however, data show that forests are on an average greater SOC sinks in comparison with agricultural land uses (Jobbágy and Jackson, 2000). Various studies have reported that conversion of forested areas into cultivated agriculture has led to an overall decline in SOC stock in those soils (Zhang et al, 2012), due to changes in soil structure, diminished microbial activity, altered aeration and moisture regimes, reduced inputs of organic matter and more intense soil erosion (Kenye et al, 2019). But better land management practices can contribute to the improvement of the condition.…”

Aim: To investigate soil organic carbon (SOC) storage and distribution pattern under paddy and forest land use along with the effect of various edaphic and environmental factors on it. Methodology: Soil samples from 12 different profiles were collected from different agriculture and forest lands across the district. Soil samples were collected at three different depth ranges 0?30, 30?60, and 60?100 cm from both agriculture and forest land. Soil samples were processed and analysed for different soil parameters in laboratory.? Results: Soil organic carbon density (SOCD) was found to be higher under forest at all depth range compared to agricultural land. But soil organic carbon storage was higher under agricultural land (1.34 tC at 0-100 cm depth) compared to forest (0.44 tC at 0-100 cm depth) land. Geostatistical method was used to estimate the total SOC storage and density (SOCD) of which density was found to be high under forest (1.21 kg m-2) but carbon stock was high for paddy field (1.34 t C). Zero order correlation and path analysis revealed significant effect of soil texture on SOCD over environmental factors in this region.? Interpretation: Information from this study can be also useful for identification of critical and potential regions in terms of carbon storage which may need immediate attention. This information will also be helpful for the policy makers in management and monitoring of natural resources and can act as an input for further research.
