Abstract

Among the land use pattern, forest soils are an important component of the global C cycle and it store large amounts of organic carbon (OC). Comparing the carbon storage in various land use systems, required to assess organic carbon in the soils. In order to that, the study was conducted on the estimation of soil C stocks in three important land use systems viz. Mango orchards, cultivated and fallow lands in the Muzaffarpur district of Bihar. For the assessment of various soil properties, the soil samples were collected from three soil depth (0-15, 15-30 & 30-45cm) using soil core cutters. Among the different age of mango tree, the increased value of organic carbon obtained in 25 years old mango orchard than 10 and 20 years old trees respectively. The soil pH differed across the land use system, where, higher value was recorded in fallow land followed by cultivated land. However, lower pH was recorded in soils of mango orchard than other land use system may be due to addition of litter leaves of mango orchard. The higher concentrations of all micronutrients were recorded higher in surface soil. The information made by study the effects of different land use types on soil organic carbon stock is crucial for best land management practices and combating climate change and enhancing ecological restoration.

Conclusion

The present study has shown that the carbon (C) sequestration can be enhanced by shifting the land use toward perennial systems. Among the land use pattern, organic matter deposition was found more in mango orchard soils than other land use system. However, among the tree age, the increased content of organic carbon value obtained with 25 years old tree orchard than 10 and 20 years old trees respectively. The higher content of macro and micronutrients was recorded in upper soil layer than lower.
