What is the term used for applying liquid nitrogen fertilizer through irrigation water?

The term for applying liquid nitrogen fertilizer through irrigation water is fertigation. This method integrates the fertilization process with irrigation, allowing for the nutrients to be delivered directly to the root zone of the plants in a more efficient and effective manner. Fertigation helps in ensuring that the nutrients are evenly distributed and readily available to the crops, promoting better growth and yield.

By using this technique, farmers can adjust the nutrient application based on the crop's specific needs and the soil conditions, leading to enhanced nutrient use efficiency. This process also minimizes the risk of nutrient runoff and leaching compared to traditional methods. The ability to apply fertilizers during irrigation can save time and labor while providing a precise way to manage nutrient delivery.
