Water for irrigation – agriculturist
Water is one of the most important natural resources as it contributes to the development and maintenance of life on our planet. It is crucial for both living things and plants. The quality of irrigation water is crucial for the growth of plants and the yield of its fruits. Each plant has its own requirements and needs in terms of concentrations of dissolved solids such as sodium and characteristics such as pH and conductivity, which will affect its evolution and growth.
The SAR index (Sodium Absorption Ratio) expresses the relationship between sodium concentration with calcium and magnesium and is an indicator of the quality of water for irrigation. A high conductivity value, combined with a high SAR (sodium concentration) value in irrigation water, can reduce or even inhibit plant growth and yield. The science of agriculture through the study of the behavior of each plant in its growing conditions determines, among other things, the quality of irrigation water. Exemplary treatment methods are desalination by reverse osmosis that removes approximately 99.5% of the salts producing low conductivity water, filtration with turbidity, bag and cartridge filters to remove suspended solids, bulk particles, water particles and turbidity, dosing systems for fertilizers and pH control, water quality control systems etc.
