An improved agricultural practices such as adjustment of application rate, application of the right amount of nitrogen, use of slow controlled release fertiliser, applying nitrogen fertilisers when least susceptible to loss, crop rotation, avoiding over-irrigation and storage of manure in concrete pits lagoons can be

Can water filters remove nitrates?

The only way to remove nitrates from drinking water is through a water filtration system. Many water treatment companies promote Reverse Osmosis (RO) systems as an immediate solution to provide nitrate and nitrite reduction.

How do you remove nitrates from water NZ?
