1: Effects of pH on Radish Seed Germination
Natural soil pH depends on the parent
rock material from which it was formed and processes like climate. Soil pH is a
measure of the acidity or alkalinity of the soil. Acidic soils are considered
to have a 5.0 or lower pH value whereas 10.0 or above is considered a strong
basic or alkaline soil. The pH of soil affects the solubility of nutrients in
soil water and thus it affects the amount of nutrients available for plant
uptake. Different nutrients are available under differing pH conditions.
