Water management
Water is of great importance for successful tomato cultivation. On an annual basis, per hectare (10,000 m2), an average of 15,000 to 20,000 m3 (15 to 20 million litres) of water are needed for cultivation. It is therefore of great importance for our growers that these processes are implemented as efficiently and sustainably as
possible. Our growers achieve this in various ways:
Rainwater
Rainwater: we collect all available rainwater in basins. These are usually constructed next to the greenhouses and range in size from 1,000 m3 to 3,500 m3 per hectare.
Reverse
Reverse osmosis: in this process groundwater is pumped up and filtered, which is mainly necessary because our groundwater is generally brackish. The clean freshwater is then available for cultivation and is pumped into the rainwater basin. The salt water, or ‘brine’, that remains after the osmosis process is returned to the ground.
