Effects of soil pH on soil flora and fauna

Influence of soil pH
– important for many organisms
– influence soil moisture tension
– affect availability of mineral nutrient
– some organisms e.g bacteria are more tolerant to low pH
– others e.g fungi are less tolerant
– affect soil structure/pore space
– soil pH affect uptake of water by plant root
– alkaline soil is unfavorable for most plant
– determined by presence of unchangeable cations
