Irrigation, as a research topic, encompasses the controlled application of water to agricultural or landscaped soils to optimize plant growth, yield, and resource efficiency under variable climatic and hydrological conditions. It includes the study and modeling of water delivery methods (e.g., surface, sprinkler, and drip systems), soil–plant–atmosphere water dynamics, evapotranspiration estimation, and scheduling strategies based on soil moisture, plant stress indicators, or climate data. Research additionally addresses irrigation water quality, salinity management, impacts on groundwater and surface water systems, energy use, and integration with precision agriculture and deficit-irrigation strategies to improve water productivity and sustainability.
One way people ingest a group of toxic chemicals known as PFAS is through consuming produce, dairy and meat products that have been exposed to contaminated soil and irrigation water. Some guidance is available on how growers ...
