How to reduce soil acidity: most useful tips for vegetable gardeners
Soil acidity affects the development and nutrition of the root system, which is the basis for a high-quality crop. The pH level determines the agrochemical properties of soils and plant growth. Acidity is formed by the concentration of H+ ions (hydrogen ions).
Excessive acidity affects the supply of nutrients, and excessively high or low pH levels have a toxic effect on the root system. Read how to reduce soil acidity in the OBOZREVATEL article.
The optimal level of acidity
Acidic soils have a detrimental effect on the crop. The presence of elements such as manganese, aluminum, or iron in the soil is harmful to plants. Crops growing in an acidic environment cannot fully receive nutrients and mineral nutrition as this weakens plants, and vegetables lose their ability to resist pests and diseases. At the same time, the activity of beneficial microorganisms involved in the decomposition of organic residues is suppressed.
The acidic environment leads to the destruction of beneficial microflora, and the high pH inhibits the growth of the root system. If the plant grows in acidic soil, the absorption of nitrogen from the air is impaired due to the poor development of nodule bacteria.
Excessively alkaline soils also adversely affect the yield: plants cannot get potassium, magnesium, phosphorus, copper and other nutrients. At the same time, urea quickly evaporates from the alkaline environment and causes damage to the root system.
Thus, it is important to maintain an optimal pH level in the garden, which is from 6 to 6.5.
How to reduce the acidity level
Dolomite flour will effectively reduce acidity. This fertilizer not only normalizes the pH level but also saturates the soil with calcium, magnesium, zinc, and phosphorus.
The yield after using dolomite flour will increase significantly.
To deoxidize the soil, you need to take 2 cups of fertilizer per 1 square meter.
