Quick uptake of nutrients
When nutrients are applied to the leaves, plants can absorb them much more quickly than through their roots. Absorption through leaves occurs within hours versus days through the soil. This allows for an immediate boost when plants are deficient or experiencing stressors that require a rapid nutrient response. The direct contact with leaves maximizes how much of the applied nutrients are actually taken up by plants.
Targeted applications
With Foliar Sprays, nutrients can be precisely placed where plants need them the most like new leaves, flowers or fruits. Soil applications rely on root uptake and distribution throughout the plant but aren't as accurately targeted. Foliar treatments ensure atomspheres, flowers and produce directly receive applied nutrients.
Supplement normal fertility programs
Foliar sprays are usually meant to complement - not replace - a soil fertility program. They provide a means to deliver extra nutrients when plant needs spike above what the soil alone can supply. Examples include heavy fruiting or flowering periods that deplete reserves, times of extreme heat or cold stress, or deficiencies identified through tissue testing.
