ALKALIN™ PK 10:20 is a liquid, high-alkaline phosphorus-potassium fertilizer (pH ≥ 11.4) with component ratio P2O5: K2O = 10:20.
ALKALIN™ is a range of specialized foliar fertilizers, which are characterized by high pH. Alkaline pH of fertilizer solutions activates the immune factors of plants and reduces fungal diseases development.
ALKALIN fertilizers differ in nutrient content and, thus, can be used at different stages of plant development. ALKALIN™ fertilizers provide the plants with necessary nutrients and at the same time, support plant protection. ALKALIN™ fertilizers are very useful in an integrated plant cultivation.
ALKALIN™ PK 10:20, due to phosphorus and potassium ratio, is recommended for autumn treatments – to improve winter hardiness of plants, as well as spring treatments – intensification of the development of vegetative parts, as well as directly after flowering – to increase crop quality parameters.

FOLIAR SPRAYS
ALKALIN™ PK 10:20 is intended for foliar application in the form of an aqueous solution. ALKALIN™ PK 10:20 can be used in combination with other preparations, keep in mind, however, that alkaline pH of fertilizer solutions (pH above 11) hinder the miscibility with many agrochemicals. To confirm miscibility, a confirmatory test is required.
Recommendations for foliar application for selected crops.
The recommendations may be modified taking into account the plants’ requirements and growing conditions.
