Assessment of chemical properties under different land use systems with four year old cultivation

Abstract The main objective of this study was to assess the chemical properties of soils under different land use systems which were conducted at Bangaluru, Karnataka during 2015. Soil samples were collected at 015, 15-30, 30-50 and 50-100 cm from five horticultural areas (cultivated with mango, cashew, rose, vegetable and medicinal and aromatic crops), the soils of experimental site was sandy loam with slightly acidic to neutral in reaction. The results showed that all the available nutrients were higher in the surface soil (0-15 cm) which was decreased with increase in soil depth in all the selected horticulture crops. Mango and cashew orchard had the highest available N, P, K, Ca, Mg and sulphur as compared to the annual crops. The DTPA-extractable Fe, Zn, Cu and Mn were also higher in these soils.
