They anticipate that the cultivation of cranberry continues growing worldwide and it will do it in hydroponic system

Experts predict a worldwide boom in cranberry cultivation, especially in those countries that are already producing Spain, Morocco and the Ibero-American countries. And one of the keys of this growth is the hydroponic system, because "it is and will continue being the one that is implanted related to this crop", assures the teacher María del Carmen Salas, agronomist of the doctorate of Protected Agriculture of the University of Almería. Professor Salas added that one of the most important characteristics of hydroponics is that "productions can be advanced".

Salas has been one of the few Spanish participants in the XVII International Seminar of Blueberrries in Seville that Blueberries Consulting has organized, and of which agrodiariohuelva It is media partner.

This seminar has brought together in Seville experts from different parts of the world, fundamentally American, to analyze the global production chain of blueberry cultivation in a monographic way.

Salas has acknowledged, however, that in Spain and fundamentally in Huelva, the hydroponic culture is rather scarce, although, he insists, it will grow.

The majority of cranberry production in Spain is located in Huelva, although there are also productions in Galicia and Asturias.

Professor Salas points out that the hydroponic systemit is a "comfortable" formula for producers that has already overcome the four-year utility barrier, which a few years ago questioned the profitability of the system. The direct contact he has with producers has shown him that the crops can use the same sack until 10 or 12 years and even more, "although in the end there is no earth but a cluster of roots, because it is impossible for it to be otherwise; However, the plant is still productive, which is important, and it is maintained ", he explained to agrodiariohuelva.

Among the advantages of the hydroponic, Salas has emphasized the precocity, in addition productions are achieved much more homogeneous that on land, diseases are better controlled by having a reduced work space and more soil quality is obtained.

Professor Salas understands that, in principle, it can be a more technical and complicated system but "only until the technician becomes familiar with the system, because in the long run the management it's much simpler than on the ground ».

About the type of substrate to be used, María del Carmen Salas has assured that there is a wide range of solutions and added that one of the keys to achieving good results is to control the acidity of Ph.

Another participant in the Seminar has been Gerard W. Krewer from the American University of Georgia and international consultant. This has participated with two presentations, one on organic and conventional nutrition and another on growth regulators in blueberries with low cold requirements.

This monographic seminar in Seville has had some 300 participants and a score of exhibitors among which were Unitec, FibreDust Europe and Pindstrup
