Question

Significance of soil ph in nutrient availability to plant

Answer 1

Soil pH of 6.5 is usually considered optimum for nutrient availability. Lower pHincreases the solubility of Al, Mn, and Fe, which are toxic to plants in excess. A critical effect of excess soluble Al is the slowing or stopping of root growth. Extreme pH values decrease the availability of most nutrients.
