THE EFFECT OF MAGNESIUM IN CHEMICAL EQUILIBRIUM FORMS OF POTASSIUM AND THE GROWTH OF YELLOW CORN IN TOW SOILS OF DIFFERENT TEXTURE

Abstract

This study was conducted to determine the effect of adding magnesium on the chemical equilibrium of potassium. The study included five levels of magnesium, Mg₀, Mg₁, Mg₂, Mg₃, and Mg₄, and two levels of potassium, K₀ and K₁₀₀, in two soils of different textures. The results of the study showed that adding magnesium contributed to increasing soluble, exchangeable, and non-exchangeable potassium. And by 64.706, 105.882, 164.706, and 235.294% / 13.986, 29.680, 47.945, and 77.169% / 4.538, 8.372, 13.224, and 26.682% for the level Mg₁, Mg₂, Mg₃, and Mg₄ compared to Mg₀, respectively. The soil with a silt clay texture outperformed the soil Silt Clay Leom texture with percentages of 131.818, 15.074 and 8.254%, for dissolved, exchangeable and non-exchangeable potassium, respectively.
