ABSTRACT
The present study was undertaken to assess the physico-chemical properties of soils in relation to depth in thirty two representative soil samples from mango orchards of four tehsils namely Kudal, Vengurle, Deogad and Kankavali of Sindhudurg district. In general, textural class for profile soils of mango orchards was found to be the category of sandy clay loam, sandy clay and clay loam. The particle density and bulk density in soil profiles did not follow any specific trend. A declining trend of maximum water holding capacity down the profile was recorded in all mango orchards. Further, the soil pH increased with depth, while electrical conductivity and organic carbon decreased with depth. A general decrease of available N, P2O5, K2O, Exchangeable Ca and Mg with depth was recorded. Furthermore, distribution of available micronutrients viz., Fe, Mn, Zn and Cu exhibited declining trend with depths. In future INM should be followed to sustain fertility status.
