DROPFERT BLUEBERRYTM 14.5/7.5/18.5 + micro
Product Description
DROPFERT™ BLUEBERRY 14.5/7.5/18.5 + micro is a crystalline, fully water-soluble fertiliser, intended for fertigation in soil, inert and organic substrates. It can be used to prepare concentrated solutions used with proportional dispensers or diluted ready for use nutrient solution.
Individual fertilisers from DROPFERT™ line differ in proportions of nutrients, to provide nutrients balance for particular stages of plant growth and development.
DROPFERT™ line fertilisers contain 100% chelated micronutrients and the highest quality macronutrients.
DROPFERT™ BLUEBERRY 14.5/7.5/18.5 + micro is recommended for in all stages of plant development, throughout the growing season, particularly for plants in poor condition.

Directions for Use
Detailed recommendations (nutrient composition and frequency of application) should be adapted to the requirements of plant species, agrotechnical and climatic conditions of cultivation (including the type of substrate).
Calculations shall take into account the content of nutrients in other fertilizers used to prepare the medium and in water used for fertigation.
- Fertigation in inert substrates, coconut peat, hydroponic cultures (nutrient solution applied continuously or repeatedly during the day). Dose of DROPFERT™ BLUEBERRY 14.5/7.5/18.5 + micro should be adjusted to balance of the main nutrients in the medium.
- Fertigation in organic substrates, soil cultures (medium applied periodically – many times during the plant vegetation period). DROPFERT™ BLUEBERRY 14.5/7.5/18.5 + micro should be used in the form of an aqueous solution with a concentration of 0.03–0.2% (0.3–2.0 kg of fertilizer in 1000 liters of ready-to-use nutrient solution).
When used DROPFERT™ BLUEBERRY 14.5/7.5/18.5 + micro with other tank-mix components do not exceed total nutrient concentration of 0.2%.
When preparing concentrated solutions, proportionally increase the dose of fertilizer.
Concentrated solutions of DROPFERT™ fertilizers should be prepared in a tank other than the concentrated solution of calcium nitrate.
