Folio Zn - Foliar fertilizer for use during zinc deficiency

Folio Zn is an organic foliar fertilizer that is used after a leaf analysis or as a preventative before periods of increasing mineral demand. Zinc (Zn) is one of the eight essential micronutrients. It is needed by plants in small quantities, but still important in a wide range of developmental processes, such as growth hormone production and internode extension. Zinc is probably the most common defect and can lead to a significant reduction in yield and quality.

In fact, the yield can be reduced by over 20% before any visual signs occur! The cost of loss of production is far higher than the cost of soil and plant tissue testing and zinc application. The mobility of zinc in plants varies, depending on soil availability or growing media. When zinc availability is sufficient, it becomes easy to translate from older to younger leaves, while when zinc is deficient, zinc movement from older leaves to younger is delayed.
Folio Zn contains a high concentration of zinc in combination with a dispersant. The dispersant ensures that the mineral has good contact with the leaf surface, and the growth has good opportunity to absorb it. The dispersant is made from plant material and is organically transferable. To best help the growths out of a mineral deficiency, Folio Zn is added energy in the form of a foliar fertilizer (Pepton). Folio Mn is absorbed in the growth within a few hours and the effect may be visible already on the same day. Folio Zn is supplied in powder form and should be mixed with water and can be used with other types of foliar fertilizers or pesticides. Folio Zn is dosed at between 50 and 200 grams (dry weight) per decar. acres.
Folio Zn is an ecologically approved corrective.

Ready formulated foliar fertilizer for use against zinc deficiency by spraying foliage in vegetables, fruits, legumes, grains and oilseeds.
Strengthens the plant's development of stems, buds and leaves. Stimulates the flower, formation and growth of the fruit.
Mix in water after desired dosage, by experience, soil or leaf analysis.

Fertilizer approved in organic farming at (EC) No 834/2007

General recommendations





Strengthens growth and development

Before flowering at risk of deficiency, otherwise after flowering is complete. Can be repeated after 10-14 days. For cork crust-prone types, treatment is usually postponed to 6 weeks after flowering.


Strengthens growth and development

Used one week after full sprouting, repeat once after 14 days, etc.

Lettuce on soil

Strengthens growth and development

10-14 days after planting / germination. In case of moderate deficiency repeat at 10-14 day intervals. Last treatment at least 1 month before harvest.


Strengthens growth and development

From the two-leaf stage to the first joint node becomes visible. In case of moderate deficiency, treatment is repeated at 10 to 14 day intervals.


Strengthens growth and development

When the buds are green or multiple treatments: When the buds are green, when the buds are white and after harvesting.
