"Uniformity of irrigation leads to optimal growth"

" Uniformity of irrigation is an crucial , mayhap the most important parameter of nursery horticulture " , says Stefan Bakker , ware manager at Revaho . With a parameter he mean a variable , mensurable property whose value is a broker of the properties of a system , such as water . Uniformity of irrigation , both in quantity and opus , top to optimum growth when other ontogenesis factors such as lighter and air are also undifferentiated . ScaleTo point the scale for the uniformity of an irrigation scheme , the product manager gives the following example . For example , a 12 - hectare capsicum company has between 300,000 and 350,000 drippers on one irrigation scheme . " If on a summertime ’s daylight you provide thirty times an irrigation of 200 cubic centimetre of water , that comes down to about 10 million water shot . These must always be the same , for the first as well as for the last industrial plant . That is quite a task!“The irrigation system must therefore have a mellow degree of truth so as to accomplish this . For the uniformity of the system of rules , three elements are significant : the tone of the components , the design and the correct use of the system . CollaborationFor the perfect timber of the intersection components in the system , the Cartesian product truth must be in conformity with a circumscribed tolerance . The output of drippers must therefore always be the same for ensure uniformness in irrigation . The installer plays a major role in the conception of the system . He must convert the wishes of the exploiter into the elaboration of the system . The uniformity of the amount of H2O that the system can supply must equalise that of the grower . The correct employment of the system is a level for the agriculturist himself . Bakker : " The cooperation and interchange of knowledge between the producer , installer and grower finally find whether the uniformity of the irrigation of a atomizer or dripper system is as optimal as potential . “Equal water distributionWhen using a spray system , there is a difference in the water dispersion in a cut blossom craw and pot plant cultivation . " When irrigating , uniformity count as the most significant parametric quantity . Irrigation water in the open field circulate better than in pots , because water does not spread from one good deal to another . Especially with very small pots the raiser want to have the same amount of pee in each dope . With a expectant pot or container , uniformity is faster . to attain the optimum solution , the right product components and manipulation of the system are therefore crucial . Because irrigation of small cuttings and plugs in tray or shock requires many more small droplets than a big pot or container , " reports the product handler . authorship of waterUniform composing of the piss is pertain to : temperature , EC and pH note value , oxygen tier and disease insistency of the water . Is this the same in the whole irrigation organisation or is it different at the beginning and end of the scheme ? In praxis , it turns out that when the companies originate and the acreages per system step-up , the uniformity of the piece of music decreases and change . This has to do with the travel sentence , the prison term the water takes to move through the organization . Because of the traveling time , plants at the start of the system receive ' unlike ' urine than the plants that are the farthermost away from the dose building block . The travel time also settle the uniformity of the irrigation . peg down traveling time in quotationBakker : " When the piece of the water is the same every day , the difference between the first and last plant is less . But if a grower gives a different plant food theme every day or during the day , the difference is greater . "

Because the change of location time is in the system design , it is important for a agriculturist to know this effect and to take this into report if he wants to make a change in the weewee composing . " The travel time , which can be calculated , must be included as a parameter in the quotation outgrowth . Because if a agriculturalist knows that his arrangement has a certain slowness , it prepare little sense , for object lesson , to use a lower EC economic value or flora protection product on a hot summertime twenty-four hours . The change composition of the water can only hand the last plant the next dawn . "
