Foliar Fertilizer

Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to their leaves. The absorption takes place through the stomata of the leaves and also through the epidermis. Movement of elements is usually faster through the stomata, but the total absorption may be as great through the epidermis.

A popular version of the feeding is to use sea-based nutrient mixes, especially kelp and silica, because they contain many of the fifty “trace nutrients”; the more “trace” is needed, the harder it is to balance the element within the soil. Trace elements are considered most fit for delivery by foliar feeding. Kelp also contains some hormones considered good for the cellular development of the plants’ leaves and roots.

Granular Fertilizer

Granular or dry fertilizer is a type of fertilizer which comes in a dry pelleted form, as opposed to spikes, a liquid, or powder. Most fertilizer supply companies carry several different types of granular fertilizer, along with an array of formulations which are designed to address specific soil conditions. This type of fertilizer has both advantages and disadvantages which customers have to consider before use.

The key advantage to granular fertilizer is that it acts as a time release capsule, allowing nutrients to flow out over time, rather than flooding the plants with nutrients like liquid fertilizers do. However, the fertilizer can also lose or leach nutrients in heavy rainfall, or in poor drainage conditions, in which case the plants may not get the full benefit of the fertilizer. Granular fertilizer can also be difficult to manage, as it needs to be applied with care to avoid damage to turf.
