Who was thinking the Fruit Logistica in Berlin was only a trade show for fruits and vegetables, Bosman van Zaal is proving wrong. At that trade show, Bosman Van Zaal met AZ Rose, amongst others, a rose oil producer from Azerbaijan. Now, less than a couple of years later the first roses have been planted in the greenhouse they build in Gabala, Azerbaijan. The total complex will be 6.3 hectares in size and has an annual production capacity of 190 to 210 stems per m².
Robert Leon Pol from the Netherlands is the senior grower for this project. At the left Evert Gelderman, who is the construction supervisor.
“In 2017 we started building this turnkey project. The first phase at their Agro Complex is now finished”, says Rob Alleblas, technical sales consultant at Bosman Van Zaal. First, a solid foundation was made. Then the heavy steel construction was build. “The first phase consists of an earthquake resistant greenhouse of 29.520 m2 and a service area of 3,110 m2, which we insulated with sandwich panels.”
He sums up some technical facts: “We have installed an energy saving screen, a gable screen, gutters, a mist system, water storage and silos, a buffer tank, drip irrigation on 10 gutters per 8 meters, pipe-rail heating, a disinfection and re-circulation system and a CO2-installation. The condenser works in two ways, one is cooling CO2 and the other is recovering extra heat from the flue gases. The well water is being purified by reverse osmosis. Cultivation is closely monitored by the iSii Hoogendoorn computer.”
Lighting and heating
“The crop is illuminated with 149 micromoles / m2 / sec. The lighting system generates light and heat, so the temperature of the heating tubes decreases as soon as the lighting switches on. To avoid cold gables and sidewalls Bosman Van Zaal installed separate heating systems with separate control and measurement.
AZ Rose also produces roses outside, but in the greenhouse they will grow some special varieties. Most of the rose oil will be exported to Russia and Georgia. “Therefore, the location is perfect, as those are Azerbaijan’s neighbor countries. I think the production of roses has huge opportunities in Azerbaijan”, says Rob.
