Using Jand and Mesquite for environmental progress and management: Improvement soil proprieties and carbon sequestration ability in different organs

摘要

The present study was conducted to estimate the amount of carbon sequestration in soil containing Jand (Prosopis cineraria) and Mesquite (Prosopis juliflora) and control area at different soil depths (0-15 and 15-30 cm), as well as its organs (root, shoot and leaves) and some soil characteristics in the Anbarabad region, southeastern part of Kerman province, Iran. This study was carried out by two separate factorial experiments. The first factor was the type of plant species in both experiments. The second factor was the plant organs in experiment Ⅰ and different soil depths in experiment Ⅱ. The results showed that the carbon stored at two depths of 0-15 and 15-30 cm in P. cineraria (21.39 and 24.36 t/ha) and also in P. juliflora was 23.70 and 24.857 t/ ha, respectively. Effects of Soil type under the canopy and soil depths on carbon sequestration were significant. Both plants had the highest amount of organic carbon in the roots and shoots. However, the lowest amount of organic carbon obtained in leaves. Effect of soil depth on carbon sequestration was significant and also the interaction of species and organs on the amount of stored organic carbon were significant. Soil texture, especially clay content, has a great effect on soil carbon sequestration. The highest carbon sequestration was obtained in Mesquite (24.03a ± 1.113 t/ha) and the lowest carbon sequestration was obtained in Jand (20.87b ± 0.203 t/ha).
