Salinity management
Irrigation water adds dissolved salts to cropland increasing soil salinity. Leaching is necessary to keep the average rootzone salinity below the plant threshold EC levels to sustain crop production. On the other hand, nitrogen loss via leaching to pollute GW is a primary concern in irrigated cropland. To better help the growers to manage soil salinity and conserve water, the website contains the following:
1. Salinity Basics

- Soil salinity effect chemical properties
- Effect of pH, sodicity, and salinity on soil fertility
3. Effect of soil salinity on crop growth
- Crop salinity tolerance and yield function
- Toxicity of specific ions
4. Salinity management
- Assessment of irrigation water quality (interpreting water analysis report)
- Diagnosis of soil infiltration caused by soil salinity problems
- Soil and water amendments
- Models to assess water suitability for irrigation (WatSuit)
