Table 5 Salinity ratings for soil based on electric conductivity
From: Soil characterization and heavy metal pollution assessment in Orabi farms, El Obour, Egypt
Rating | EC (μS/cm) | Effect on plants |
|---|---|---|
Non-saline | 0–2000 | Salinity effects are mostly negligible |
Slightly saline | 2000–4000 | Yields of very sensitive crops may be restricted |
Moderately saline | 4000–8000 | Yields of many crops restricted |
Highly saline | 8000–16,000 | Only tolerant crops yield satisfactory |
Extremely saline | > 16,000 | Only a few very salt-tolerant crops yield satisfactory |
