  5. HI-Q Ca-B


HI-Q Ca-B (Calcium-Boron) is a plant-based leaf liquid integrator that reduces the occurrence of underlying calcium and boron deficiencies. HI-Q Ca-B helps prevent calcium and boron deficiency symptoms, resulting in improved photosynthesis and reduced fruit drop.

HI-Q range is a complete range of innovative solutions combining our Plant Stimulating Peptides and a high content of micronutrients, for a strong nutritional and biostimulant action. The presence of PSP, coming from the Vegetal Protein Hydrolysates (VPH), improves the ability of plants to absorb nutrients in order to better prevent or cure nutritional deficiencies and disorders. All HI-Q solutions are to be applied foliar, so that the action is even quicker and effective. HI-Q Ca-B is designed to prevent and cure Calcium physiological disorders and Boron deficiencies. It is ready to use and thanks to its high solubility and assimilation ability, it helps plants to quickly overcome the stress induced by nutritional imbalance, also improving photosynthesis and reducing fruit drop. Created to counteract nutrient deficiencies, HI-Q Ca-B addresses sustainable agriculture practices. Ideal for use as a foliar fertilizer, HI-Q Ca-B can be safely paired with insecticides, fungicides, growth regulators, adjuvants, biocontrol protects, and other foliar fertilizers.

Boron (B)
Is used with calcium in cell wall synthesis and is essential for cell division (creating new plant cells). B requirements are much higher for reproductive growth, so it helps with pollination, and fruit and seed development. Other functions include translocation of sugars and carbohydrates, nitrogen metabolism, regulation of hormone levels and transportation of potassium, which helps regulate internal water balance. Since B helps transport sugars, its deficiency can reduce the attraction and colonization of mycorrhizal fungi.

Calcium (Ca)
Has a main role as a structural nutrient in the plant, being essential for cell division and playing a core role in the stability of cell walls and cell membranes. Calcium prevents sensitive calcium physiological disorders, in many crops, like tip burn, blossom end rot, bitter pit and fruit cracking. Ca is fundamental for fruit quality; it improves fruit firmness and fruit shelf-life.

Vegetal Protein Hydrolysates
HELLO NATURE ’s Vegetal Protein Hydrolysate products are made exclusively from the highest quality, non-GMO vegetal sources and are guaranteed to contain no animal by-products. They are produced using a proprietary Enzymatic Hydrolysis process and naturally contain organic nitrogen, organic carbon and Plant Stimulating Peptides.

Plant Stimulating Peptides (PSP)
The result of our exclusive Enzymatic Hydrolysis process. This pool of selected peptides has a prominent, assured, and natural biostimulant effect to enhance root development, seed germination and emergence, improve nutrient uptake, mitigate the effects of abiotic stress and increase fertilizer efficiency. PSP also help to prevent diseases by increasing health levels in plants.
