Blueberry cultivation requires growers to obtain high yields to be a profitable crop. There are several factors that can reduce production, and one of the most common and important is the lack of a strong root system.
The PMA (Blueberry Microbial Program) strategy allows to obtain more absorbent roots, which make better use of all the available soil, and also to stimulate blueberries at critical moments such as fruit set, just after flowering, when potential production is being determined. These aspects are key and essential to get the most out of the plantation.
To achieve the above, the PMA Strategy has been designed and developed, which consists of microbial formulations and biostimulants of plant origin. It is mainly based on an inoculation of ericoid mycorrhizal fungi and a specific stimulation at specific phenological moments.
PMA Strategy
The PMA Strategy (Blueberry Microbial Program) is mainly composed of Bioradis Ericoid, a formulation based on ericoid mycorrhizal fungi, specific and exclusive for blueberry cultivation. It also contains Bactel Frut, a formulation based on 5 species of PGP bacteria of the Bacillus genus , with stimulating and protective action.
To accompany and enhance the applications of microorganism formulations, it is recommended to combine them with Saviavital K, a liquid organic fertilizer that promotes good activity of the microorganisms applied, or with Alghefit, a pure algae extract with stimulating activity and activation of protective genes.
This PMA strategy allows obtaining crops with a larger root system, which translates into greater absorption and greater tolerance to different types of stress, such as thermal stress, drought or stress caused by soil pathogens. This promotes high production levels and high fruit quality at harvest (hardness and caliber), while making better use of other inputs used, such as water or fertilizer.
The following are results obtained in trials in blueberry plantations in the province of Huelva (Spain), following the PMA strategy. In this case, an 18.2% increase in harvest was obtained, as well as a larger fruit size compared to the Control plot.
