Irrigation with treated wastewater changes soil properties

Treated wastewater is increasingly being applied as freshwater resource for crop irrigation. Much attention is being paid to the effects of (emerging) contaminants on the environment. However, wastewater can also change the physical properties of soils and affect the availability of water to the plant roots, as is shown by this paper by Loy et al. 2018. Their study aimed to quantify and evaluate the effects of treated wastewater irrigation on the water holding ability of the soil as compared to rainfed/dryland conditions. They show that that irrigating with treated wastewater decreases the ability of the soil to hold water, which negatively affects the water availability for plants. Nevertheless, for their case study, irrigation with treated wastewater still increases crop yields. Therefore, although negatively affecting soil physical properties, irrigating with treated wastewater can still be a suitable water conservation practice. Crop production can be increased, while exploitation of groundwater from aquifers is reduced; the resource-sustainability of regions can thus be improved. ...
