Growing blueberries in hydroponics allows for the first year of production to get 50% more yield than the traditional method of cultivation. Moreover, the crop ripens earlier, that gives the producer an additional benefit.
This conclusion was reached by Grupo Projar after an 8-year experiment in the main producing countries of North America, South America, Europe and Africa, freshplaza reports.
As it turned out, in the first year of production, hydroponic plantations yielded up to 15 t/ha compared to the maximum 10 t/ha on ordinary ones. In the second year, the yield reaches 20 t/ha (versus 15 t/ha traditionally cultivated).
In the third year, the farmer can already get 20 tons of blueberries per hectare, rather than 18 tons per hectare, as on a conventional plantation.
At the same time, the company notes that the important aspects of hydroponic berry growing are the frequency of irrigation, the microclimate, the type of water, etc.
The hydroponic method is particularly relevant in regions with heavy and basic soils. Substrates also guarantee high aeration capacity, which contributes to the proper development of plant roots.
Experts also note that blueberries are very sensitive to excess moisture, and with hydroponics, perfect drainage is achieved.
