Water technology is an up - to - particular date and multifaceted theme and moreover with the necessary interface with other nursery gardening issues , such as greenhouse climate and new , fossil - free energy sources . Leo Oprel , Sr . policy police officer at the Dutch Ministry of Agriculture , Nature and Food Quality ( LNV ) , deals with the orbit of vitality , water and impregnation and observes that up closely there is more and more more interlocking of these issues and that is in line with the LNV vision . He will point out on various growth .
" A summer like 2018 makes us once again cognizant of the usefulness of the various aspects in the field of body of water technology " , enounce Oprel . " Long - term lack of hurry increases the importance of storing rain in the subsoil , in aquifers . This is not only a good computer storage space , but also worthy in the context of combat salinization . specially if more is stored than eventually used .
Therefore in this eccentric it is potential to coalesce business with pleasance . A kind of social contribution from the sector . It can also contribute to the drainage of rainwater , as well as forbid that in teetotal summers your basin lacks good irrigation pee and thus reverse osmosis or poorer surface body of water - which is also scarce , has to be used . In any case , overrule osmosis on saline groundwater is something that has to be phase out for years . "
Less ventilationAccording to Oprel , this also should be an item in restructuring . " It ’s not only about what happens above ground , but also surreptitious . And for the western part of the Netherlands this is in effect against salinization , but in the east groundwater is also an offspring . This year a lot of groundwater was extracted in the east . And that has yet to be refill . In poor , an important takings for both the greenhouse horticulture sector and for other sectors . "
He also mentions atomization as an number in water applied science . " You need very pure water for it because it require a very fine cliff . After all , the crop must not get wet . With atomisation you’re able to hold in the passion load with minimum ventilation . That open a secure greenhouse clime and is part of Next coevals Growing . ”
The fineness of the drop may differ depending on the equipment , but is crucial for the custom . The finer the better . Although I do not know what the technical restriction is . In any case , less airing is good again to limit the entire water phthisis and of course for CO2 . Also more effective role of good water for greenhouse horticulture is , not only elsewhere in the world , but also with us , of importance . "
Precision irrigationWith the use of heat retrieval from greenhouse air , you also gain ground back weewee . This reduce the need for water for growth . Here , an energy - saving greenhouse climate and more efficient water management go hand in hand . " you’re able to employ dissimilar methods to that purpose , as various study show . The question is whether we have already reached the limit or whether it still can be done intimately or other than . "
At thetomato cultivation at the Improvement Center also a dissimilar substrate is looked at , Oprel continues . " It is very little substrate and that gives new attention to preciseness irrigation . When do you have to get the drip ? Do you first need to reduce the wet ( and see the shank psychiatrist ) or learn from it that you have to dribble x minutes earlier before the stem psychiatrist ? That leads to great discussion with the researchers . In that trial , fertilizer is also well looked at . So underground in relation to above ground . And although it has advantages to irrigate exactly , it does take more attention from the certainty that everything is performing well . "
Of vital importance for more than just works growthWater engineering also affects geothermal get-up-and-go and Ate ( Aquifer Thermal Energy Storage ) . There , according to the insurance officer , still a identification number of things have to be settled . " In geothermic energy you have to deal with aggressive water supply and at ATES it is usually not too sorry . But the efficiency must be as high as possible with a high reliability of optimum heat use . There is still an improvement step to be made with suppliers . "
Although the efficiency of ATES in greenhouse horticulture is generally good than outside the sphere , there are always still some improvements and lour of the toll potential .
" So piss and water technology has more facets and interface with climate and vigour when you call up about it " , says Oprel in end . " Water is of critical grandness , but not only for works growth . It has become much wider in modern greenhouse gardening . "
