Soil acidification primarily results in a decrease in soil pH, which indicates increased acidity in the soil environment. This can occur due to various factors, such as the leaching of basic cations, the application of acid-forming fertilizers, or the natural decomposition of organic matter.

As soil pH declines, it impacts the availability of nutrients essential for plant growth. Certain nutrients, like iron and manganese, may become more soluble and available in highly acidic conditions, while others, such as calcium and magnesium, may become less available, leading to nutrient deficiencies for plants.

Overall, a lower soil pH can adversely affect soil health, microbial activity, and plant growth, making it crucial for farmers and land managers to monitor and manage soil acidity effectively.
