Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to the leaves. [1] Plants are able to absorb essential elements through their leaves. [ 2 ] The absorption takes place through their stomata and also through their epidermis .
Iron sulphate (Iron(II) sulfate) and iron EDTA are only useful in soil up to PH 7.1 but they can be used as a foliar spray (Foliar feeding). Iron EDDHA is useful up to PH 9 (highly alkaline) but must be applied to the soil and in the evening to avoid photodegradation. EDTA in the soil may mobilize Lead, EDDHA does not appear to.

Other functions attributed to calcium are: the neutralization of organic acids; inhibition of some potassium-activated ions; and a role in nitrogen absorption. A notable feature of calcium-deficient plants is a defective root system. [14] Roots are usually affected before above-ground parts. [15] Blossom end rot is also a result of inadequate ...
Selectivity is determined by the circumstances and technique of application. Climatic factors affect absorption including humidity, light, precipitation, and temperature. Foliage-applied herbicides will enter the leaf more readily at high humidity by lengthening the drying time of the spray droplet and increasing cuticle hydration.

In one study, a foliar spray containing phosphite inhibited the growth of P. cinnamomi by over 90% in plants infected two weeks after spraying, and by 66% in plants infected one year after spraying; yet most plants infected shortly before or after spraying were dead 100 days later, while nearly all plants infected seven months after spraying ...
