Physico - chemical characteristics of salt affected soil from Barhanpur, M.S., India B. S. Mali, S. S.Thengal, P. N. Pate Department of Botany, Tuljaram Chaturchand College, Baramati, M. S., India _____________________________________________________________________________________________ ABSTRACT Salt affected areas, due to excess irrigation are major problem all over irrigation the world. Due to excess irrigation, the salt present in the water remain saturated in the soil. Assessment of seasonal variation in the salt concentration is a tool for knowing the status of saline soil. In the present work an attempt is made to study the seasonal variation in physiochemical properties viz. E.C., pH and mineral composition of the agriculture supporting salt affected soil from Barhanpur site. These studied parameters show seasonal variation. Key words: Physicochemical characters, salt affected areas, soil. _____________________________________________________________________________________________ INTRODUCTION The problem of salt affected soil is a case of global occurrence and it affects developing as well as developed countries. Nearly 20% of worlds cultivated area and nearly half of the worlds irrigated lands are affected by salinity. Salt – affected soils could be produce as result of use of salt containing irrigation water, presence of high amount of salt in the soil and high level of ground water table [15]. Saline soils lose their productivity and possibility of turning them into unproductive once [9]. Crop varieties differ in their response to various biotic and abiotic stresses. Excessive salt concentrations decrease water potential and thus result in reduced water availability to the plant. Under such situations plants often show wilting...
