Soil pH is a measure of the acidity or alkalinity of the soil. It is an essential factor in determining the ability of plants to absorb nutrients from the soil. The pH scale ranges from 0 to 14, with 7 being neutral. A pH value below 7 is considered acidic, and a pH value above 7 is considered alkaline. Each plant species has a specific soil pH range in which it grows best, and this range varies depending on the type of grass or plant you are trying to grow.
The pH level of soil affects the availability of nutrients for plants. When the soil is too acidic or too alkaline, the nutrients in the soil become less available to plants, and they cannot absorb them properly. For example, aluminum and manganese become more soluble at low pH levels, and their excess can become toxic to plants. On the other hand, at high pH levels, minerals such as iron, zinc, and copper become less soluble, and their deficiency can cause stunted growth, yellow leaves, and fungus diseases in turfgrass like Zoysia, Bermuda, and St. Augustine.
Soil pH is also essential for the growth of beneficial microorganisms in the soil. These microorganisms help break down organic matter and convert it into nutrients that plants can absorb. Some microorganisms thrive in acidic soil, while others prefer alkaline soil. The soil's pH level can affect the balance of these microorganisms, which can significantly impact the overall health of the soil and the plants growing in it.
Testing the soil pH is a crucial step in determining the right fertilizers to use in the soil. Fertilizers that are not compatible with the soil pH can be less effective and can even harm plants. For example, applying lime to alkaline soil can further increase the soil's pH level and make it even more alkaline. Similarly, applying sulfur to acidic soil can further reduce the pH level and make it even more acidic.
Testing the soil pH regularly can help ensure that the soil is in the optimal pH range for the plants growing in it. By maintaining the right soil pH, plants can absorb the necessary nutrients, and beneficial microorganisms can thrive, leading to healthy and lush plant growth.
