Definition as written by capewellmj:

Foliar Fertilizers are fertilizers that are applied to foliage to boost nutrient density in crops and to correct nutrient deficiencies. The main benefits of foliar spraying is that it can have up to a 90% efficiency rate of uptake as opposed to a 10% efficiency from soil applications. Also it becomes immediately available in the plant because they are 100% water soluble. This makes them perfect for correcting nutrient deficiencies. Soil amendments may take several days to take affect and the nutrients may be tied up with other elements and made unavailable to the plant.

The other great thing is that foliar spraying stimulates the plants to create exudates in the roots which excite microbes to work harder and thus increases nutrient uptake from the soil. Foliar sprays are a great supplement to boost flavors, sweetness, mineral density and yield from your crops.

Ensure you use high quality, safe, non-toxic fertilizers from a company you trust. Alot of companies are selling fertilizers with poisons, cheap ingredients, low nutrient concentrations along with badly and inconsistently mixed formulas. This will reflect in the quality and flavor of your foods. Martin Capewell -
