INIA 8302 are assessed. The osmotic effect causes a greater absorption of cations, potassium being the element most readily absorbed. The specific effect of magnesium sulphate causes a decrease in the total of anions and in the water content of the plant and partly offsets the decrease which the osmotic effect produces in the fresh weight T2 - Plant and Soil ER -
