Dynamics of physico -chemical properties of soil in response to hilly aspects in community forest, Rampur Palpa

Abstract

This research was objectively conducted to assess physico-chemical properties of soil among aspects. Total 64 soil samples were collected from 0 to 10 and 10-20 cm depths from North East, South East, North West and South West aspects. The physical and chemical properties of soil were analyzed in the lab. Average moisture content was found highest at North East aspect (39.46±1.11%) at 0-10 cm depth and 37.52±0.96 % at the depth of 10-20 cm. Nitrogen content was the highest 0.378±0.03% at 0-10 cm depth and 0.362±0.04 % at 10-20 cm depth in North East aspect. The amount of Potassium in the forest was found highest at North East aspect with the mean ±SE value of 523.76±75 kg/ha at 0-10 cm depth and 418.92±28.09 kg/ha at 10-20 cm depth. Phosphorus content was found to be highest again at North East aspect which has the mean±SE value of 28.202±2.22 kg/ha at 0-10 cm depth and 25.89±2.51 kg/ha at 10-20 cm depth, Similarly, organic carbon content was found highest again at North East aspect with mean±SE value of 2.18±0.06 % at 0-10 cm depth and 2.031±0.05 % at 10-20 cm depth. Elucidating pH content, the highest value was found at North West aspect with mean value of 6.32±0.19 at 0-10 cm depth and 6.02±0.21 at 10-20 cm depth respectively. Value of C:N at North Eastern aspect was recorded 5.80 at 0-10 cm depth and 5.55 at 10-20 cm depth. The study will be useful for researcher for the further work in soil science.
