Soil pH has a lot to do with plant nutrient availability, soil structure, and crop growth. The organic nutrients in the soil can only be converted into state nutrients for plants to absorb through the participation of soil microorganisms, and most of the microorganisms involved in the decomposition of organic matter grow and develop in a near-neutral environment, so the effectiveness of soil nutrients is generally It is better when it is close to neutral reaction. Second, soil pH also affects soil structure. In acidic soil, the concentration of hydrogen ions and calcium ions are replaced and leached out, so the acidic soil is easy to harden. Alkaline soil contains a large amount of replaceable sodium ions and hydroxide ions, which make soil particles dispersed and harden after drying, resulting in poor structure of alkaline soil. In addition, soil pH is also closely related to plant growth. In nature, some plants have strict requirements on soil acid and alkali conditions. They can only grow within a specific acid and alkali range. These plants can play an indicator role for soil pH, so they are called indicator plants. We can choose suitable crops for planting according to the soil pH according to local conditions; or adjust the soil pH to an appropriate range according to the crops.
