What is a significant effect of high soil acidity?

High soil acidity can significantly impact plant health due to its effect on nutrient availability and uptake. When soil pH levels drop, certain essential nutrients become less available to plants. Specifically, nutrients like phosphorus, calcium, and magnesium may bind to soil particles or become less soluble, making it harder for plants to absorb them. Additionally, high acidity can lead to an increase in toxic elements, such as aluminum, which can further hinder root growth and nutrient uptake. Consequently, plants in highly acidic soils often exhibit symptoms of nutrient deficiency, stunted growth, and overall poor health, highlighting the critical relationship between soil acidity and plant nutrient availability.
