fields are irrigated by sprinklers or drip. While both are
effective for commercial production, one major advantage of drip
is the capability to apply water-soluble fertilizers during
irrigation. This procedure, otherwise known as fertigation, can
apply fertilizer very uniformly throughout a field and directly
to the roots in small amounts as needed. Liquid fertilizer is
usually injected from April to mid August with fertigation.
Granular fertilizer, on the other hand, is commonly used with
sprinklers and is usually applied in two or three large doses
each spring. We did a study to compare fertig
