What is the effect of low pH levels on plant health?

Low pH levels in the soil indicate increased acidity, which can have several detrimental effects on plant health. Most plants prefer a soil pH within a specific range, generally between 6.0 and 7.5, as this range optimizes nutrient availability. When pH levels drop below this range, certain nutrients, particularly essential ones like calcium and magnesium, become less available to the plant. This lack of availability can lead to nutrient deficiencies, limiting the plant's ability to grow and thrive.

Moreover, acidic conditions may also impact the beneficial soil microbiome, reducing the effectiveness of processes like nitrogen fixation and organic matter decomposition. As a result, plants may experience stunted growth, poor vigor, and reduced overall health. Therefore, understanding and managing soil pH is critical for maintaining optimal growing conditions and ensuring the well-being of plants in any greenhouse or agricultural setting.
