The study was conducted to determine the long-term impact of different land uses
on carbon sequestration, soil fertility, and microbial indices and to establish their
interrelationship in a light-textured hyperthermic Udic Ustochrept. Soil samples were
collected from existing land-use systems of (1) Eucalyptus tereticornis, (2) Terminalia
chebula, (3) Acacia nilotica, (4) Leucaena leucocephala, (5) Embilica officinalis, (6)
Zizyphus spp., and (7) maize–wheat rotation from depths of 0–15, 15–30, and 30–45 cm
and examined for pH; organic carbon (OC); electrical conductivity (EC); available
nitrogen (N), phosphorus (P), and potassium (K); micronutrients; microbial biomass
carbon (MBC); microbial biomass nitrogen (MBN); and microbial biomass phosphorus
(MBP). High-density plantations of Eucalyptus teriticornis had a greater potential
in sequestering aboveground carbon (472.37 Mg ha−1), compared to widely spaced
trees of Acacia nilotica (376.05 Mg ha−1). Eucalyptus teriticornis exhibited the greatest
impact in increasing soil OC in all depths, followed by Acaccia nilotica and Terminalia
chebula, and the lowest was in agriculture (0.778, 0.749, 0.590, and 0.471%, respectively,
in surface soil). Available zinc and iron contents were greatest under Eucalyptus
tereticornis, followed by Acacia nilotica, Zizyphus mauritiana, Embilica officinalis,
Terminalia chebula, and Leucaena leucocephala. The MBC and MBN were greatest
in Eucalyptus tereticornis, followed by Acacia nilotica, and lowest in agriculture.
Correlation matrix revealed significant and positive relationships between carbon
sequestered with OC, MBC, MBN, and MBP.
