Potential of native mycorrhizal inoculants on plants of agricultural interest

In agroecology, the origin of native inoculants is fundamental when it is necessary to determine species effective in promoting the growth of plants of agricultural interest, since the less disturbed the soil of origin is, the greater the possibilities of finding infective and effective species.

▶ In this regard, numerous experimental investigations have evaluated biocompartments, in the search to know the potential of arbuscular mycorrhizal inoculants native to different soils, following a gradient of land use (tropical forest, cultivated soil and pasture), in order to find highly effective species in promoting the growth of plants of agricultural interest without the use of agrochemicals.

It has been reported that soils exhibit a high mycorrhizal potential capable of significantly stimulating plant growth compared to plants fertilized with synthetic products, hence the high mycorrhizal dependence of the plants of most cultivated plants is well documented.

However, the mycorrhizal potential of the soil from the tropical forest has shown a greater richness of species but also a greater effectiveness of these species as potential inoculants of plants of agricultural interest free of chemical residues toxic to the health and balance of the agroecosystem.

In agroecology, it is convenient to study the effectiveness of arbuscular mycorrhizal inoculants in their multiple functions, in the crop of interest under greenhouse conditions and later in the field, evaluating the individual effect of promising species, as well as mixtures of species or mixed inoculants, to verify their complementarity and synergistic effects.

In this sense, the ideal is to first analyze the effect of inoculation with native inoculants on plants of agricultural interest during the different phases of their phenological cycle, on the dry biomass of the scion, higher content of mineral elements in the plant tissue and acceleration of the flowering phase with respect to non-inoculated plants, with the objective of evaluating the synergistic effect of each native inoculant.
