Present research was undertaken to examine the impact of land use
on soil fertility in an Alfisol, at Dharamshala district of north western Himalayan
region, India. Soil samples were collected from 0-15, 15–30, 30–45 and
45-60 cm soil depths of five landuses viz. natural forest of Pinus roxburghii,
grassland, horticulture, agriculture and wasteland. Soil was examined for
pH, organic carbon (OC), electrical conductivity (EC), cation exchange capacity
(CEC), available nitrogen (N), phosphorus (P), exchangeable calcium
(Ca), magnesium (Mg), potassium (K), aluminium (Al), microbial biomass
carbon (MBC), microbial biomass nitrogen (MBN), microbial biomass
phosphorus (MBP), acid phosphatase activity (APHA) and dehydrogenase
activity (DHA). Soil pH varied from 5.22 in forest and 5.72 in grassland.
OC content was higher in forest (3.01%), followed by grassland (2.16%)
and was least (0.36%) in deeper layers of agriculture. Highest N content
was found under forest (699, 654, 623 and 597 kg/ha, at 0-15, 15-30, 30-45
and 45-60 cm depth, respectively), followed by grassland, horticulture and
agriculture and least in wasteland. Maximum exchangeable Ca and Mg were
found in grassland (0.801 c mol kg-1 and 0.402 c mol kg-1, respectively).
Exchangeable K and Al were higher under forest (0.231 c mol kg-1 and 1.89
c mol kg-1, respectively) least in wasteland. Soil biological properties were
highest under surface soil of forest (576 mg kg-1, 31.24 mg kg-1, 6.55 mg
kg-1, 29.6 mg PNP g-1h-1 and 35.65 μg TPF 24 h-1 g-1 dry soil, respectively
for MBC, MBN, MBP, APHA and DHA) and least in 45-60 cm layer, under
wasteland. The forest had a higher fertility index and soil evaluation factor
followed by grassland, horticulture, agriculture as compared to wasteland.
