Kingfol Zinc

Kingfol Zinc is a highly concentrated single element suspension liquid fertilizer designed to correct zinc deficiency.

Kingfol foliar nutrients are formulated using high quality mineral elements, to give the following benefits:

• Concentrated liquid formulations to minimise handling, packaging, transport and application rates
• Widely tank-mixable with agrochemicals
• Formulated with uptake enhancers to optimise performance over time
• Disperses easily with no need for pre-mixing
• Single element formulations to correct specific deficiencies

Conforms with Regulation (EU) 2019/1009 of the European Parliament and the Council of 5 June 2019 (EU fertilising products)

Throughout the world Zinc deficiency is the most widespread of all the micronutrients. It stimulates enzyme activity within the plant and can be associated with calcium in deficiencies such as bitter pit. Applications of foliar zinc often stimulate rooting and are particularly useful in early crop growth.

Foliar absorption
The use of unique enhancers allows the nutrients to enter the plant by two main pathways, one acting quickly and the other more slowly. This provides a mechanism for sustained uptake over time. The quick uptake is achieved by direct entry via stomata on the surface of the leaf.  This relies on good coverage from the foliar spray. To maximise uptake via this route, addition of a good quality wetter, such as OMEX SW7 is recommended. This leads to stomatal flooding, allowing maximum absorption.

The slower, sustained uptake is brought about by the uptake enhancers in the formulation. These work by stimulating the microbes which live naturally on the surface of the leaf – sometimes referred to as the epiphyllic micro organisms. These help solubilise the remaining foliar spray. Once in ionic form, it then passes into the plant by diffusion through minute aqueous pores in the leaf cuticle.

Kingfol Zinc prevents and corrects zinc deficiency.
