The evaluation of soil quality is essential in monitoring the long term
effects of rice cultivation. Present study investigated the effects of long
term rice cultivation on soil properties and organic C pools and identified
indicators for monitoring soil quality in Ghaggar-flood plains of hot arid
India. Soil samples were collected from fields with 0, 10, 20, 30 and
40 years of rice cultivation. The study revealed that electrical conductivity
(EC) and exchangeable sodium percentage (ESP) increased after
30–40 years of rice cultivation. Available nutrients increased with increas-
ing years of rice cultivation. The organic carbon pools namely, total
organic carbon (TOC), Walkley Black carbon (WBC) and particulate
organic carbon (POC) were increased above 50% in 20 and above years
of rice cultivation. The TOC and POC were increased by 40.6 to 132.4%
and 31.7% to 104.8% in 10 to 40 years of rice cultivation. Cation
exchange capacity, WBC, ESP and CaCO3 could serve as soil monitoring
indicators of long term rice cultivation in arid region. The findings clearly
indicated that long term rice cultivation could aggravate soil salinity and
have negative impact on soil quality in arid environment.
