What is Foliar Feeding?
Foliar feeding addresses the immediate needs of a growing crop, as opposed to long-term soil deficiencies, by spraying water-soluble fertilizers onto the leaf surface of the plants. All plants absorb nutrients through their leaves and stems, using stomata—little openings similar to the pores of our skin. Plants absorb foliar sprays 20 times faster than soil-applied nutrients. Foliars help plants compensate for soil deficiencies (low fertility, low soil temperature, etc.) during the growing season.
Foliar feeding can also be timed to encourage and/or enhance critical points in the plant’s growth cycle, such as rapid growth phases or flowering, fruiting and seed formation. Many crops benefit from 6–8 foliar applications per season. Some growers apply weekly foliars at low concentrations to improve nutrient balance.
