Recommendations on the procedure and volume of water supply during land flushing

---

1. Before carrying out leaching of saline lands
✅salinization of field soil
✅mechanical composition of soil
✅removing the water used in salt washing
that is, the working condition of the drainage
✅groundwater depth
determination and technology of salt leaching
it is necessary to make the right choice.
2. Salt leaching should be carried out during periods when groundwater is deep.
3. In addition, in autumn, it is necessary to deeply loosen the soil or carry out plantation plowing.
4. In non-saline and slightly saline lands, spring irrigation is sufficient, and the water volume is determined by the free volume of the aeration zone, which depends on the mechanical composition (porosity) of the soil and the state of groundwater.
Recommendations prepared jointly with the Karakalpak regional center of the Research Institute of Irrigation and Water Problems.
