N solution is commonly used in agricultural practices as a nitrogen source to enhance plant growth. It is applied in fertigation systems, delivering nitrogen directly through irrigation water for improved nutrient uptake. Due to its high solubility and availability, it supports rapid greening of crops and turf, making it valuable in both farming and landscaping. It is also utilized in controlled environments like greenhouses where precise nutrient management is required. Additionally, N solution serves in wastewater treatment to adjust nitrogen levels and support microbial processes in biological treatment systems.
