GENERAL INFORMATION
Sukra AA Pack combines calcium, boron, and zinc in a single foliar product with amino acids. Used in the USA for over 10 years and in Europe since 2011. Commercially launched in 2014, it has shown yield increases of up to 400 kg in sunflower and 180 kg in soybean.
This fertilizer allows the simultaneous application of three traditionally incompatible elements (Ca, B, Zn), thanks to its amino acid formulation, achieving nutritional efficiency and cost reduction.
Compatible with agrochemicals, it can be mixed with insecticides, fungicides, and herbicides without reducing their effectiveness.
Calcium promotes strong roots and general plant vigor. Boron facilitates flowering and sugar transport. Zinc regulates metabolic processes and protein synthesis.
Especially recommended for protein-rich crops such as soybean and sunflower.
HOW DOES THE FORMULA WORK?
- Enhances vigor: Calcium helps with nitrogen absorption, boron transports polysaccharides, and zinc forms enzymes for protein synthesis.
- Development: Boron and zinc stimulate growth hormones like IAA and increase carbohydrate metabolism.
- Biological action: Overcomes common deficiencies in alkaline soils through nutrient interactions that improve uptake.
ADVANTAGES
- Essential for seed fertility
- Increases pollen fertility
- Involved in protein synthesis
- Supports grain filling and weight
- Participates in sugar metabolism and transport

Foliar Application
- Fruit trees: 2 kg/ha max. 1% — at floral buds, pre-flowering, petal drop, and fruit set. For reserves: 4 kg/ha max. 2% in autumn.
- Olive trees: 2-3 kg/ha max. 1% — spring, 15 days later, and post-harvest.
- Vineyards: 2 kg/ha max. 0.5% — at inflorescences, floral buds, and fruit set. For reserves: 4 kg/ha max. 2% in autumn after harvest.
- Vegetables: 3 kg/ha max. 0.4% — 2–3 applications starting from well-rooted plants, every 15 days.
