Soil macronutrients (P, K, Ca+2 and Mg+2) showed significant differences between the altitudes (P<0.05). Mean soil macronutrients; Mg, P K concentrations were significantly higher at altitude than those lower altitude, whereas mean concentration was altitude. micronutrients, Mn+2, Na, Zn+2, Cl_, Al_ Co also In conclusion, our results indicate that topographical factors, slope aspect in this pre...

Abstract: Soil pH has a major effect on plant nutrient availability by controlling the chemical structure of the nutrient. Adjusting soil acidity or alkalinity improves soil nutrition without adding extra fertilizers. Soil nutrients needed by plants in the largest amount are referred to as macronutrients. In addition to macronutrients, plants also need trace nutrients and both macro and trace n...
