Irrigation water quality is crucial at the start of finish . The young crop is vulnerable and can suffer considerable terms if the water quality is not good . At the start of a new craw on substrate , a lot of fertilized water is used before the plants arrive . In this process , careless operations can moderate to losses of large amounts of water and fertiliser , especially at four position in the system : 1 ) cultivation sewer , 2 ) assembling at the end of finish gutter , 3 ) drain pit , and 4 ) drain tanks . right planning of filling and drain the mats can ensure that discharges from overflowing gutters and tanks are avoided . Arthur van den Berg of Glastuinbouw Nederland explains more at Glastuinbouw Waterproof .
1 ) Prevent overflow of the drainage channel when drain the substratum slab . When making the full drain curve out directly , the slab drain completely in a very shortsighted clip , creating a undulation of water that spills over the border of the drain channel onto the ground . By first prick a drainpipe cakehole with a dripper , for example , the mat can run out slowly . Then , after drain , the waste pipe cold shoulder - out can be made .
2 ) Avoid overspill of the drainage from the drain line to the drain pit . If too many matting are drained out at the same clock time , a undulation may form in the drainage manger , stimulate overflow from the catch basin . By starting at the catch basin and moving further and further away from it , overflow can be prevented .
3 ) Prevent overflow of the drain pit . The drain colliery has a heart that pump the water to the hold up tanks . If more pee go into the drain Inferno at the same time than the pump can handle , the drainage pit will overflow . Therefore , do not allow more mats to drain at the same sentence on the same drainpipe pit than the discharge content of the pump in the drain pitfall . A properly operate float is also crucial at this stage . Therefore , train the float for performance and murder any blockage .
4 ) Avoid outpouring of the drainage tank ( dirty and white ) . The drain tank have a modified volume for drain water storage . All the water discharge when crossbreed the substratum mats should be able to be gather in these tanks . If the memory capacity is limited , it can be chosen to fulfil and debilitate the slabs in phases , for example , per rap section or grouping of tap sections . The pee released during drainage of the first section can then be reused ( possibly after disinfection ) to fill the next section .
A point of attending is the capacity of the pee discussion unit ( e.g. , disinfector ): this can also be define in perplex the weewee from the dirty to the clean drain tank fast enough to permit reuse .
Analyse enfeeble water more frequentlyDuring the lead off - up phase angle , you could analyze the pouring body of water more frequently for cleansing and plant protection product residues to assess whether you could recycle the drain water . check for hydrogen peroxide ( H2O2 ) for reuse of the cleansing water supply in cultivation is easy to do with test strip . Other means require psychoanalysis in a research lab . One has the result after a few years .
