In the process of fertigation in irrigation systems, fertilizer is applied directly with the irrigation water. Therefore, wherever the irrigation water goes, the fertilizer goes with it. Fertilizer is applied only where needed, and in the proper quantities. The obvious advantages of fertigation in irrigation, therefore, are the saving of labor and machinery, and the efficient use of the costly chemicals and fertilizers to be applied. In fertigation, the extra activities involved in the separate application of fertilizer are no longer necessary; neither is the purchase of maintenance of dedicated equipment for fertilizer distribution. Additionally, such machinery often compresses the soil and may cause crop damage. In conclusion, one might say that fertigation is the most effective and least expensive way of proving nutrients To growing field irrigated crops.
