Blueberry cultivation requires producers 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 Strategy allows for obtaining more absorbing roots, which make better use of all the available soil, and also stimulates blueberries at critical moments such as setting, 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 inoculation of ericoid mycorrhizal fungi and specific stimulation at specific phenological moments.
The PMA Strategy
The PMA Strategy is mainly composed of Bioradis Ericoid, a formulation based on ericoid mycorrhizal fungi, specific and exclusive for blueberry cultivation. It also includes Bactel Frut, a formulation based on 5 species of PGP bacteria of the Bacillus genus, with a stimulating and protective action.
To accompany and enhance the applications of formulations with microorganisms, it is recommended to combine with Saviavital K, a liquid organic fertilizer that promotes good activity of the applied microorganisms or with Alghefit, a pure algae extract with a stimulating activity and activation of protective genes.
This PMA Strategy allows for 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 caused by soil pathogens. This promotes high production levels and high quality fruit at harvest (hardness and size), while making better use of other inputs used, such as water or fertilizer.
Below are the results obtained in trials of blueberry plantations in the province of Huelva (Spain), following the PMA Strategy. In this case, an increase in harvest of 18.2% and a larger size of fruit were obtained, compared to the Control plot.
