Managing salinity when irrigating with greywater
One of the potential impacts of using greywater is increasing salt content in your soil (especially if GreySmart household products are not used).
Many washing powders use salt as a filler so as a general principle liquid detergents are likely to be better. For the advice on using best products, consult the guides provided in GreySmart Products. Salt has a long term irreversible impact on soil structure in the end making it infertile. Salt tolerant plants cope better with salt but can’t ‘fix’ the soil. It is always better to not put salt in your greywater in the first place.
If you are not sure if the household products you use are GreySmart then avoid concentrating greywater in one area of your garden. Also avoid using more greywater than is required to maintain a healthy garden and monitor the health of your plants and the state of the soil where you use greywater.
