Physico-chemical parameters and elemental analysis of the soils of sunflower (Helianthus annus. L) growing field with different manure treatment

In this study, an attempt has been made to find any possible variation in Physico-Chemical parameters of the soils collected from various sunflower fields (sandy loam & red soil) with root rot diseases in three different manure treatments viz; control (T1), chemical fertilizer (T2) and organic manure (T3). Also the concentrations of four important trace elements viz., Fe, Zn, Mn and Cu are estimated using Atomic Absorption Spectrometer (AAS). The results of the Physico-Chemical parameters, the concentrations of trace elements and their results are discussed.
