Soil Organic Carbon Stock in Various Block Plantation Systems: A Case Study from Navsari, South Gujarat, India

Abstract

The study was carried out to assessment the concentration and stock of soil organic carbon (SOC) across nine different types of block plantation systems with randomized block design in three replication in South Gujarat, India. Soil samples at different depths (0–10, 10–20 and 20–30 cm) were collected from each of the block plantation under study to estimate SOC content in the laboratory. Thus, bulk density of soil ranged was from 1.28 to 1.42 Mg/m3 in different depth of soil under block plantation land use systems. Perusal of the plantation of trees data indicate that the available soil organic carbon was found highest (AP; 0.88%) in A. procera, which was at par with tree plantation of T. grandis (TG; 0.86%), T. arjuna (TA; 0.82%), D. latifolia (DL; 0.82%) and M. indica (MI; 0.81%), M. achras (MA; 0.80%). While it was lowest in Eucalyptus clones (EC; 0.77%) respectively. In addition,find out the depth of soil increased the bulk density. From the investigation of this research paper we concluded the top soil surface layer (0-10 cm) showed maximum soil organic carbon concentration.
