irrigation water qualityの例文
- Research, which is carried out in three scales : regional, irrigation and farm, looks at : distribution of salt-affected land in Iraq, impact of water and salt on agricultural productivity, the relationship between groundwater salinity and irrigation activity, irrigation and drainage infrastructure, best adapted salt-tolerant crops and approaches to drainage management and improvement of soil and irrigation water quality.
- Water quality objectives are set and periodically revised by regulatory agencies, such as the EPA, to define the limits of water quality for different uses, which include human health, but also other ecologically important functions, wildlife habitat, irrigated agriculture, etc . For example, if the irrigation water quality objective for salt is 450 mg / L of total dissolved solids, the assimilative capacity of a water body would be the amount of salt that could be added to the water such that it's concentration would not exceed 450 mg / L.
