Abstract

                                The soils of the Regional Research Station, Vridhachalam, a substation of Tamil Nadu Agricultural University which is a typical representation of the north eastern zone oilseed growing area were investigated for their diagnostic and physico-chemical characteristics. The studios were carried out by analysing profile and surface soil samples from individual fields. The soils have been found to, come under the order Altisols in the soil taxonomy group. The absence of salinity and sodicity problems and also the lateritic nature was brought out. The soils were found to be poor in N &P and medium to high in available K. while the status of Fe and Mn can be conside- red as satisfactory, the availability of Zn and Cu appear to be critical.
