Agro Fossil Free - Impact of Amide Fertilizer on Carbon Sequestration under the Agroforestry System in the Eastern Plateau Region of India

Algemene Beschrijving

Carbon sequestration is an important aspect of expelling greenhouse gases from the atmosphere and decelerating the rate of global warming. Agroforestry plays an important role in carbon sequestration. Keeping this in mind, the current study was carried out between 2017 and 2021 to assess the effect of integrated nutrient management on biomass production, carbon sequestration, and carbon credit in a mango and turmeric agroforestry system. The study used randomized block design (RBD) with four treatments and five replications. According to the findings of this study, the rate of fertilizer application has a significant impact on the growth of turmeric and mango crops. The physiochemical characteristics of soil show an improvement in soil composition with the application of urea (CO(NH2)2), single super phosphate [Ca(H2PO4)2.2H2O] 226 kg ha−1, MOP [KCl] 309 kg ha−1 100 kg ha−1. The carbon density of the agrihorticulture land use system was six to seven times higher than that of the open agriculture-based land use system. The highest turmeric production (8.98 t ha−1) was reported under the mango-turmeric system rather than turmeric alone (6.36 t ha−1) in the T2-N100kg treatment. Total biomass production (61.2 t ha−1 and 64.6 t ha−1), carbon stock (38.6 t ha−1 and 41.06 t ha−1), carbon sequestration (246.5 t ha−1 and 299.5 t ha−1), and carbon credit (246.57 credits and 299.5 credits) were found to be highest in mango and turmeric-based agroforestry land use system treatments T2-N100 kg and T3-N80 Kg, respectively. The net additional profit from the agrihorticulture land use system was 299.5 carbon credits, which is equivalent to 4,49,250 INR.
