Nitrification is a microbial process through which ammonia is converted into nitrate, which is an essential nutrient for plant growth. This process typically occurs in two main steps: first, ammonia is oxidized to nitrite, and then nitrite is further oxidized to nitrate. One of the byproducts of nitrification is hydrogen ions (H+), which are released into the soil solution.

The release of hydrogen ions contributes to an increase in soil acidity, leading to a decrease in soil pH. When fertilizer containing nitrogen is applied to the soil, it enhances nitrification, thereby increasing the amount of hydrogen ions generated. As a result, the overall effect is a more acidic soil environment, which is reflected in the decrease of pH.

This understanding is crucial for nutrient management because it affects not only the availability of nutrients for plant uptake but also soil health. Maintaining an appropriate pH is vital for optimal nutrient absorption, and understanding nitrification's impact on soil pH helps in making informed decisions regarding fertilizer application and soil amendment practices.
