“…Soil organic matter (SOM) contributes to soil fertility and crop growth by numerous ways such as the binding and buffering of plant nutrients (Murphy, 2015), providing habitat and food for soil organisms (Sapkota et al, 2012;Aldebron et al, 2020), maintaining soil moisture (Lipiec et al, 2006) and improving the soil structure (Masri & Ryan, 2006;Simansky et al, 2013). Besides these functions, SOM is a form of carbon sequestration and is therefore important for mitigating greenhouse gas emissions (Lal, 2004;Iranmanesh & Sadeghi, 2019). Organic matter (OM) is added to the soil by organic manures and crop residues and leaves the soil by mineralization due to decomposition.…”

“…Similarly the correlation between OM and K is expected as an increase in OM increase the CEC of soils, making K fixation higher (Weil and Brady, 2017). The correlation between OM and ECe dS/m is interesting as an increase in ECe dS/m directly reduces the decomposition of OM in the soil (Iranmanesh and Sadeghi 2019). A decrease in OM decomposition will also result in a decrease of available P which further explains the results in Table 3.…”

The southwestern coastal regions of Bangladesh (SWCRB) are highly exposed to saltwater intrusions brought about through cyclones and storm surges. These salinity intrusions are contributing to soil and water salinity in the coastal areas. This study aimed to determine the impact of these salinity intrusions on the quality of water and soil in three vulnerable coastal areas. In this investigation, water and soil samples were collected and analysed for pH, electrical conductivity (EC) and other trace elements. The analysis found many of the parameters to be higher than the recommended values. The study found that in soil samples there was a significant correlation between OM and ECe dS/m, as well as K and TN; and a highly significant correlation between TN and OM. This study further examined the historical salinity data at low and high tides to determine any patterns occurring alongside storm surges and cyclones. Water salinity statistics were obtained from the three locations of the Bangladesh Water Development Board (BWDB), which neighbours the study area. A Digital Evaluation Model (DEM) predicts the salinity induced by storm gushes in the corresponding impacted zones. Lastly, the study compared projections for future storm surges at current and predicted sea levels. Potential storm gushes circumstances from 1 to 9 m can impact up to 33% of the nation and 97% of the Shyamnagar Upazila. The occurrence of cyclone-related storms will increase and make cultivation and settlement in the region difficult. The predicted sea-level rises and saltwater contamination will intensify the adverse effects of salinity.

“…It has been reported that a slight increase in pH is beneficial for supporting plant diversity which might have a positive impact on SOC (Zhang et al 2021). Also, EC is an important parameter to be studied in SOC studies as both very high and very low values of EC cause reduced growth of plants in a way affecting the SOC (Iranmanesh and Sadeghi 2019;Stadler et al 2015).…”

Comparative Assessment of Tree Carbon Sequestration Potential and Soil Carbon Dynamics of Major Plantation Crops and Homestead Agroforestry of Kerala, India

Designing sustainable food and agricultural systems is a pressing need at a time when we already are at the low end of achieving SDG 13 (Climate Action) of reducing carbon emissions. In such a scenario, this study has the potential to provide an insightful framework for policymakers. The major objective of this study is to estimate the carbon sequestration of tree crops, and soil analysis in homestead agroforestry systems (AFS), monocropped rubber plantations, and monocropped coconut plantations in the Alappuzha and Kollam districts of Kerala. The soil carbon parameters analyzed were soil organic carbon (SOC) and labile carbon. Other parameters, such as pH and electrical conductivity of soil, were also measured. The soil of rubber plantations had the least pH (4.8) and EC (79 µS/cm). We found the tree carbon sequestration of rubber trees in the plantations to be the highest (13.8 t C ha −1 year −1 ) followed by homestead AFS (2.68 t C ha −1 yr −1 ) and coconut tree plantation (2.08 ± 0.53 t C ha −1 year −1 ). The tree carbon sequestration potential was significantly (p = 0.003) influenced by the treatments. In soil, the SOC content was highest in the homestead AFS (2.48%). The labile carbon was also found to be higher in the homestead AFS (0.06%) but was least in rubber plantation (0.04%). These results indicate that even though the tree carbon sequestration of homestead AFS is lesser compared to that of large tree plantations such as rubber. The soil carbon pools and other physical and chemical properties of soil promote the valuable contribution that homestead can play in the sustainability of the environment and ensuring food security.
