GROTAB 3in1 is a natural fertilizer enhanced with two types of microorganisms acting asbiostimulants on plants via the roots. Both work symbiotically to improve resistance to disease and to advance nutrient uptake. Mycorrhizal fungi increase the root surface from 100 to 1,000 times its size, greatly increasing the absorption of nutrients and water. Our specialized strain of Trichoderma atroviride increases absorption of nutrients, enhances the effective use of nitrogen, and increases solubility of nutrients in the soil. In addition, it stimulates the formation of rootlets and the colonization of the rhizosphere and root by other beneficial micro-organisms.

Trichoderma Atroviride MUCL45632
Hello Nature’s exclusive, patented strain of a beneficial fungus that naturally occurs in soils and plants. Once applied, it stimulates plant development and improves plant productivity increasing absorption of nutrients, effectiveness of the use of nitrogen and solubility of nutrients in the soil, in particular phosphorus. This fungus is also able to induce the formation of rootlets and stimulate the colonization of the rhizosphere and root by other beneficial microorganisms.

Mycorrhizal Fungi
A naturally occurring fungus found in both plants and soil which stimulates a symbiotic association between plant roots and specific fungi of the soil. Mycorrhizal fungi colonize the plant roots and provide them with mineral elements and water they extract from the soil through an external net of hyphae, while the plant supplies the Mycorrhizal Fungi with radical organic compounds and sugar. Both of Hello Nature’s exclusive, patented strains of Mycorrhizal Fungi (Rhizoglomus irregular and Funneliformis mossae) are developed using the “In Vivo Technique,” which produces more effective and resistant mycorrhizal fungi.

Organic Matter
Primarily composed of carbon, organic matter in soil has direct benefits for agricultural production. Soil organic matter plays a vital part in enhancing soil fertility and quality, on three levels: chemical (capacity to store and supply essential nutrients), physical (improve soil structure and water holding capacity), biological (enhance biodiversity, improve microorganisms’ activity, and capture carbon).
