Understanding Carbon Sequestration in Sugarcane Plant-soil System: Influence of Nutrient Integration Practices in Indo-Gangetic Plains of India | Chapter 7 | Research Advances in Environment, Geography and Earth Science Vol. 9

 

Sugarcane is a versatile crop with significant potential for carbon sequestration in both soil and plants. This study assessed the carbon sequestration in planted sugarcane and rhizospheric soil under various nutrient management practices. According to the IPCC, rising global temperatures due to GHG emissions are a primary cause of global warming. To stabilize global temperatures, it is essential to mitigate anthropogenic CO2 emissions and enhance the sequestration of surplus atmospheric CO2 in plants and soil. Sugarcane cultivation plays a crucial role in this process, as it is a C4 plant with high efficiency in utilizing CO2 during photosynthesis. One approach to enhance CO2 capture is through improved nutrient management practices, which can increase chlorophyll synthesis and nitrogen efficiency in sugarcane. Different treatment compositions can enhance photosynthesis, leading to greater CO2 capture. Consequently, sugarcane crops and their rhizospheric soils act as important carbon sinks, contributing to atmospheric decarbonization and global cooling.

 

Soil Properties and Carbon Storage: The study results indicated that soil physical and chemical properties varied significantly among treatments due to the application of different organic amendments. Soil organic carbon (SOC) was analyzed and ranged from 0.47% to 0.67%. The different organic amendment treatments notably improved soil bulk density, porosity, and carbon storage.

 

Plant Carbon Storage: Carbon stocks in various sugarcane plant parts, including roots, shoots, and leaves, were significantly different across treatments. The highest carbon stock was found in leaves (877.08 kg ha-¹) under T6, followed by roots (668.74 kg ha-¹) in T2, and shoots (422.77 kg ha-¹) in T5. This indicates that leaves stored 30.41% and 107.58% more carbon than roots and shoots, respectively, while roots stored 58.18% more carbon than shoots. The total carbon storage in sugarcane biomass, including aboveground and belowground parts, varied significantly across treatments. The mean carbon storage in aboveground parts (leaves and stalks) was significantly higher (1239.65 kg ha-¹) than in underground parts (roots) at 621.73 kg ha-¹. These findings demonstrate that sugarcane farming practices can effectively enhance carbon sequestration, contributing to climate change mitigation. The sugarcane crop and rhizospheric soils act as important carbon sinks in the decarbonisation of the atmosphere, ultimately reducing carbon levels and causing global cooling.

Understanding Blue Carbon and Need of Mangrove Productivity: Reviewing Different Projects along with Assessing their Success Rates and Suggesting Alternatives | Chapter 8 | Surviving Sundarbans: Tragedy and Hope, Edition 1

In this research paper, a detailed explanation of blue carbon and carbon sequestration is undergone. A special emphasis has been laid on Sundarban, as it serves to be the delta, having large mangrove forests. The mechanism of carbon capture of mangroves is explained. Also, a comparison of carbon-capturing capacities of different mangrove species is done. Different factors like salinity, temperature, soil type etc. which cause differences in carbon sequestration capacities of different mangrove species are enlisted. Special adaptations that mangroves require to survive in saline conditions are discussed. Discussions about various techniques for improving mangrove productivity till date are conducted. It is observed that although various scientific approaches and afforestation strategies are suggested by the Government to increase productivity in Sundarban, still results are still not as per expectations. The probable reasons behind such failures are highlighted, among which proper site selection, species variety selections and community participation are considered. Threats which are increasing mangrove mortality rates are emphasized. Lastly, alternative approaches like economic valuation methods and guidelines for the plantation of mangroves as bonsai in households are suggested.

Spacing Effects on the Growth and Carbon Storage of Plantation-grown Trees in the Njala University Tree- Spacing Experimental Plots, Southern Sierra Leone | Chapter 8 | Emerging Issues in Agricultural Sciences Vol. 1

 This study distinguished the tumor and element storage of Tectona grandis, Gmelina arborea, and Terminalia ivorensis cultivated at four various structure in the five-old age-old organize trial plots at Njala University; Southern Province, Sierra Leone. The structure selected were 1.8 m x 1.8 m, 2 m x 2 m, 3 m x 3 m, and 4 m x 4 m. The study determined the effects of these structure on shrub progress limits and element storage in the same-ground sapling biomass. The variety were cultivated in square plots consisting of four various structure. Data was composed on sapling height, width at feelings crest, and crown breadth. The dossier were subjected to reasoning of difference (ANOVA) to decide meaningful differences in sapling tumor and element depository under different organize levels at P < 0.05. Results disclosed that organize had a statistically meaningful effect on basic area per hectare (P = 0.001) and crown breadth (P = 0.001), accompanying the irregularities of total forest height (P = 0.354), width at conscience crest (P = 0.234), stand book (P = 0.131), biomass (P = 0.114) and biomass carbon (P = 0.114). The results imitated the 1.8 m x 1.8 m organize to introduction conditions of total forest height (3.4 m) and basic region per hectare (2.15 m2 ha-1). The 2 m x 2 m present highest in rank results for diameter at bosom altitude (9.18 cm) and stand book accrual (5.29 m3 ha-1), while biomass (26.4 kg) and biomass carbon (11.86 kg C) were topmost in the 3 m x 3 m organize. The most expansive organize 4 m x 4 m ruled in terms of crown breadth increase (4.776 m). The results imply the choice of organize as a key determinant in carrying out the destined administration aims of plantation institution.
