The technical solution proposed is related with agriculture, soil biotechnology, and specifically with the production and application of arbuscular mycorrhizal fungi, a microorganism that improves the efficiency of plant nutrient absorption, water level, vegetable production, protection against some root diseases, etc. It consists of a liquid product to apply arbuscular mycorrhizal fungi, starting from using an aqueous medium that allows to achieve a mycorrhizal propagule stabilization, which enables soil aggregate development and a checked viability in liquid medium between 12 and 18 months that can be used in irrigation and fertigation systems; it can be applied directly in the field or protected crop greenhouses, besides allowing the improvement of spore dormancy mechanisms and achieving a high concentration level that enables its handling and transportation. By applying this product, mycorrhizal fungi can be managed in crop under large scale irrigation systems, achieving better productive and environmental conditions.
