Be aware : The above mentioned talked about stages of highest focus tend to be measured against a new drinking water application rate involving 10,000 m^3/hectare/ yr, the approved best. In the event the rate regarding h2o application will increase additional, and then the utmost concentration amount should accordingly always be reduced. In the event the charge regarding water used can be lower when compared with 10,000 m^3/ hectare/ calendar year, after that the most focus level since talked about over must become managed.
