The soil properties of the different land uses were studied in various landscape
positions in lower Himalayan watershed of India. Soil properties such as bulk
density showed lowest value in forest land use with mean value of 1.15 Mg m-3.
Sand and silt contents were more in nalabed and agriculture-fallow land use,
respectively in lower landscape, whereas clay content ranged from 6.7 to 27.2% in
whole watershed. The soils of the entire watershed were acidic in nature. The
organic carbon content was found in increasing order of forest > degraded forest >
scrub > orchard > agriculture > nalabed. Organic carbon content was recorded
lower in agricultural land use than forest because of soil disturbance by intense
cultivation on slopping lands. The total nitrogen (Total N) content was higher in
forest land use of upper landscape (0.13 to 0.22 % with mean value of 0.16%) than
other other land use systems. Available P varied from 0.8 to 31.2 kg ha-1 in the
entire watershed with higher values in agriculture land use (mean value of 19.5 kg
ha-1) due to continuous application of phosphatic fertilizer. Whereas available K
was higher in forest land use (158 kg ha-1) than the other land use in watershed. The
present investigation revealed that land use has a great influence on soil properties
mostly through its effect on soil organic matter and total N. It was evident from the
study that cultivation on the various landscape position have resulted in a
significant deterioration of soil properties especially in physical and chemical
attributes.
