  5. MYR Ca-B


Myr Calcium–Boron is an organic, plant-based leaf liquid integrator that uses Plant Stimulating Peptides to prevent calcium and boron nutrient deficiencies. Myr Calcium-Boron allows plants to experience a quick absorption of the elements to provide Boron for fruit setting and pollen fertility, and Calcium for fruit quality traits.

Hello Nature uses organic ingredients in Myr Calcium-Boron to promote sustainable agriculture practices, prevent physiological disorders, and increase resiliency in growth throughout the life cycle. This unique formula includes high quality micronutrients to increase shelf life, improve fruit setting, and reduce fruit drop, all while also improving fruit quality and sustainability. The nutrients in Myr Calcium-Boron are quickly absorbed by the plant to promote effective deficiency recovery, which is a direct result of the calcium and boron benefits.

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.
