Czym jest
Phosphate is the form of phosphorus that plants take up. In water it comes from minerals, fertilisers and detergents, and public suppliers add a little to protect pipework. It is reported for hydroponic growers because it affects how much phosphorus the nutrient solution needs.
Skąd się bierze
Natural phosphate comes from phosphate-bearing rocks. Agricultural run-off, sewage effluent and detergents raise it, and treated mains water usually contains a small dose added to reduce lead and copper pick-up.
Dlaczego ma znaczenie
There is no drinking-water limit and phosphate is not a health concern. In open water it drives algal growth. For hydroponics the point is simply to know the starting level so the feed recipe can allow for it.
Co można z tym zrobić
Growers usually adjust the nutrient recipe rather than treat the water. Where a very low or controlled baseline is wanted, reverse osmosis gives a clean starting point.
