Foliar Fertilizer

Rapid Nutrient Application

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.

Foliars fortify plants facing other types of stress as well, such as drought, heat, cold, mechanical or insect damage or the onset of disease-susceptible periods. Foliar feeding can also be timed to encourage and/or enhance critical points in the plant’s growth cycle, such as seedling emergence or 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.

Increase the effectiveness of your foliar fertilizer

These materials are selected for their desirable effects in combination with soluble and liquid sprays. They increase effectiveness by enhancing coverage, life, or uptake (the plant’s ability to take up materials being sprayed). A few tips for Foliar Feeding:

  • Foliar feeding should not be done in the heat of the day. Leaf stomata (pores) close at temperatures above 850
  • Foliar feeding is best done in the early hours of the day, because spraying in the evening may encourage powdery mildew. If evening feeding is necessary, do it a couple of hours before sunset
  • If using a micronized substance, be sure that it is fully 'in solution' before spraying. Less soluble powders may also need frequent agitation during spraying

Fertilizing through an irrigation system is referred to as Fertigation. Historically, the products used (known as “injectables”) in this type of application have primarily been conventional (nonorganic), or, if organic, uneconomical. Now that micronized organic fertilizers have been developed, these limitations have been minimized. Irrigation lines should always be cleaned after fertigation by flushing with clean water before and/or after fertilizing.

When to Apply

We prefer to apply our organic liquid fertilizer “EcoGreen” early in the  morning or late afternoon so the ultra violet rays from the sun doesn’t sterilize the beneficial biology in our extract fertilizer, if it’s raining or the soil and plants are wet you can apply at any time as the organisms will use this available moisture to colonize the plant and soil while at the same time be protected from the suns radiation.
