Nitrification
The biological process of oxidizing ammonia nitrogen by soil bacteria into nitrate, which is the form most easily absorbed by plants.

Nitrification is a vital stage in the nitrogen cycle that converts ammonium into mobile nitrate ions. This process relies on aerobic soil conditions, sufficient moisture, and balanced pH levels to maintain optimal microbial activity for sustained crop nutrition.
Farmers manage this process by maintaining proper soil structure and aeration to support the bacteria responsible for the conversion. Because nitrates are highly soluble, they can easily move through the soil profile, making water management a critical factor in nitrogen availability.
A common error is applying fertilizers when soil temperatures are too low or moisture levels are excessive, which slows down the conversion rate. This leads to inefficient nutrient uptake and increases the risk of nitrate leaching into groundwater.
