Özet:

 


Soil organic carbon (SOC) is a key component in
maintaining soil quality. Mapping the local scale variations in the
distribution and stratification of SOC and other soil quality parameters across
different layers has always been a challenging task, in the current global
scenario of changing climates. The study was aimed to investigate the spatial
distribution of SOC and other soil quality parameters including SOC
stratification ratio and CN ratio in a small hilly watershed (̴ 10 km2)
located in the mid Himalayan region of Himachal Pradesh, India. Soil samples
were collected in November 2015, from 75 points at two depths (0-15 cm and
15-30cm), along with their geographical coordinates using a Global Positioning
System (GPS). The results revealed that SOC concentration (g kg-1)
decreased with increasing soil depth, throughout the study area and differed
significantly (P75. The overall results indicated that a higher degree of soil quality
existed at the higher elevation regions of the watershed. Majority of the soils
in the watershed accounted for only 60% of the maximum possible value of SQI,
which necessitates the adoption of better management practices for improving
the soil quality.
