Spanish firm New Growing System is targeting its production method of a multi-layer trough built in polyethylene at new growers in the UK.
The layers are connected through holes either at the bottom or sides of each layer, which allow the roots to grow without restrictions, as well as maintain high oxygen levels on the nutrient solution as it flows through the different levels, causing a waterfall effect.
The number of layers used depends on the crops involved, agronomist Diego Pozancos said. “Installation of our table-top system is easier than other hydroponic production systems,” he told freshinfo.
The system is in widespread use on strawberry production in Huelva, as well as on salads grown in Almería. Installations are also underway in Italy and Mexico, and there are trials in Belgium, the Netherlands and the UK, at Maidstone in Kent. The firm has established a relationship with Berry Gardens and is now looking to expand its links with UK growers.
“The advantages of our system are that strawberry crops can be left year after year,” said Pozancos. “Lettuce is easily harvested and there is no need to recondition or disinfect the soil or replace/sterilise the substrate. This last feature is particularly interesting for tomato and pepper growers.
“There are also environmental advantages in not applying fertilisers to the soil. It also offers water-saving advantages over conventional and substrate production. Our system can make more efficient use of labour.
“As well as strawberry growers, we are looking to target lettuce and tomato growers in the UK,” added Pozancos.
