Description
Key effects:
For Crops with High Zinc Requirements
Provides highly efficient foliar delivery and rapid correction of zinc deficiencies during periods of intensive vegetative growth.
Intensive Growth and Development
Supports the production of growth hormones (auxins), helping prevent rosetting and developmental disorders while promoting proper shoot and root growth.
Improved Pollination
Zinc is involved in the activity of more than 300 enzymes and supports pollen quality and fertilisation, contributing to higher yield potential.
Effective Under Challenging Soil Conditions
Foliar application bypasses limited zinc availability in soils with pH above 6.5, as well as in calcareous and micronutrient-deficient soils.
Macronutrient Support for Better Zinc Use
Nitrogen, potassium, and sulfur support zinc uptake and transport, helping optimise its metabolic utilisation.
The role of zinc in crops:
- Regulates the hormonal balance of the plant and favourably influences the photosynthetic process
- Increases resistance to fungal diseases and prolongs the “green leaf” effect
- Influences quality and quantity of the yield: high starch, oil and vitamin content.
- Improves efficiency of nitrogen fertilisation
Zinc deficiencies result in:
- Chlorosis: white-yellow spots on leaf tips
- Dwarfing of plants
- Reduction in the formation of flower buds
- Shortening and curling of leaves, in extreme conditions leaf dieback may occur
- Shortening and dieback of lateral shoots, which can occur in extreme conditions
Dosage and application:
| Crop | Dose (l/ha) | Number and Timing of Treatments |
|---|---|---|
| Sugar Beet | 0.5-1 | 3 treatments: from the 4-6 leaf stage to canopy closure (BBCH18-39) every 12-14 days |
| Apple and Pear Trees | 0.75-1.5 | 3-4 treatments: 1-2 treatments as a preventative measure or after symptoms of zinc deficiency and 2 treatments: a few weeks before the harvest to improve the basic stability and correct color of the fruit (BBCH 55-59), at intervals of 12-14 days |
| Berries | 0.75-1.5 | 3-4 treatments: 1 intervention or supplementary treatment, in autumn – after harvest up to 3 treatments, every 12 days (recommended dose 1l/ha) |
| Maize | 0.75-1 | 2 treatments: from the 3-5 leaf stage (BBCH 15-18) every 7-12 days |
| Other Field Vegetables | 0.5 | 1-2 treatments: at any stage of development, when symptoms of zinc deficiency appear on the plants or during periods unfavorable for zinc uptake, at intervals of 12-14 days |
| Winter Oilseed Rape | 0.5 | 2 treatments: in autumn from the 4-6 leaf stage to two weeks before the end of autumn vegetation (BBCH 20-25), in spring from the start of vegetation to the beginning of bud development (BBCH 30-51) |
| Legumes | 0.5-1 | 2-3 treatments: from emergence to flower bud stage (BBCH 21-59), every 9 days |
| Ground Vegetables with High Zinc Requirements | 0.5 | 3 treatments: first during intensive growth, after at least 8-9 leaves have developed, subsequent treatments at intervals of 12-14 days (also recommended when deficiency appears) |
| Cherries and Plums | 0.75-1.5 | 5-7 treatments: in spring – 2 treatments from the bud burst to the green bud stage (recommended dose 0.75-1.0 l/ha), in summer (especially on apple trees) – several treatments after June bud drop (recommended reduced dose 0.1 – 0.15 l/ha), after harvest: up to 3 treatments, 14 day intervals (recommended dose 1.5 l/ha) |
| Spring Cereals | 0.3 | 2 treatments: from the 3-4 leaf stage to the earing stage (BBCH 13-51), at intervals of 12-14 days |
| Winter Cereals | 0.5 | 3 treatments: in autumn – one treatment from the 3-4 leaf stage until two weeks before the end of autumn vegetation (BBCH 13-25), in spring – 2 treatments from the start of vegetation until the end of the stem elongation stage (BBCH 25-51) |
| Potatoes | 0.5-1 | 2 treatments: from the shoot formation stage until 40% of the final weight of the tubers is reached (BBCH 35-73), at intervals of 12-14 days |
VitaFer® Extra Zn can be used at the indicated developmental stages of crops or when symptoms of zinc deficiency are found on crops in order to eliminate them.
