Fertilizer may be applied in liquid form through the irrigation system rather than surface applying dry granular material. This process is known as “fertigation.”
There are some advantages to fertigation, including:
•Fertilizer is more efficiently used.
•Fertilizer may be applied weekly in small amounts so that it is more available when the plant needs it.
•Application cost is considerably less.
•Nutrients more quickly reach the root zone in a soluble form.
•Nutrient application is more precise.
It is important that the irrigation system functions properly and all plants receive the same amount of water. If water distribution is erratic, some plants may be under fertilized while other plants may receive more fertilizer than is needed.
