A new 15,000 cubic metre reservoir has just been completed, that will provide 100% of Volmary (formerly Delamore Yong Plants) irrigation water.
The reservoir catches the rainfall from 60,000 square metres of glasshouse and polythene greenhouse, all piped underground to the reservoir. The water is then moved to a centralised processing unit where it undergoes sterilisation and fertilisation using electromagnetic plate conversion of copper ions through an Aquahort system. It is also Ph corrected as is the nutrient level with a Priva system to suit the specific crops that are being irrigated.
It is hoped that the precise control of the nutrient levels with much softer rainwater will assist the growing team in the production of high quality young plants and in the massive reduction in harmful chemicals such as Nitric and Citric acid.
It has been known for a long time that a controlled level of cupper ions in the water can contribute considerably to the prevention of fungus attacks. Especially from Pythium and Phytopthora. These two fungi form spores which are easily spread in watery environments. Laboratory tests show that these are killed instantly when exposed to Aqua-Hort treated water.
At the same time the entire nurseries internal irrigation has been upgraded to include new water saving nozzles that reduce overall use significantly with no detrimental effects on the successful propagation of young plants.
The six-month project has been part funded with the assistance of the European agricultural fund for Agriculture. Lead contractor was Hortech systems of Holbeach.
Managing director Wayne Eady said: "Despite the scale of the project and the potential distractions for the nursery team, the contractor alongside our own team have worked really well to complete the task successfully. We are grateful to the European fund for their contribution and the project would not have been viable without their help. In the current unpredictable and difficult horticultural climate, substantial investments are hard to justify but if you believe in the long term future of the industry and of our place in it, continued investment is critical to maintain business momentum."
