Biocat+ OSAA for Tunnel Farming


Tunnels are a less sophisticated and therefore cheaper form of greenhouse, normally constructed from metal frames covered with polythene film.  They are easily erected and can be reallocated without great cost if required.

With an ever changing climate, tunnels offer protection from the elements for both the plants and the people engaged in the cultivation of the crops.  Tunnels vary in size and can accommodate the cultivation of both ground and raised bed forms of growing crops.

As crops are protected from the effects of both extreme heat and the cold, the growing season can be extended, especially beneficial is the heat retention at the end of the normal growing season, and this extended season is of great benefit of growers of all types of produce. Crop growing in tunnels is an intensive form of agriculture suited to the cultivation of high value crops and encompasses a range of benefits to the grower. The work environment for both propagating and harvesting is controlled, ensuring the better management of irrigation, the application of nutrients, reduction in disease, better husbandry and harvesting procedures, and better welfare for staff. The application of Biocat+ OSAA as a biostimulant has the added benefit of keeping the irrigation pipelines clear of build up of algae. The tunnels therefore offer the opportunity of higher worker satisfaction, better quality products with increased yields, and higher profitability.
