Explanation:

Fertigation is the injection of fertilizers, soil amendments, and other water-soluble products into an irrigation system. The benefits of fertigation methods over conventional or drop-fertilizing methods include: Increased nutrient absorption by plants, Reduction of use in fertilizer, chemicals, and water needed. The elements like nitrogen, phosphorous and potassium are used in fertigation. Reduction of soil erosion issues as the nutrients are pumped through the water drip system. Leaching is decreased often through methods used to employ fertigation.
