Water Testing Information
|
| Water Data | Critical Levels for Concern | |
| Water pH | < 5.0 or > 8.5 | |
| Carbonates and Bicarbonates | >120 ppm HCO3 | |
| (meq L-1 and mg L-1or ppm) | > 15 ppm CO3-2 | |
| Total Salinity (Impact on Turfgrass Growth) | ||
| ECw (dSm-1) Electrical Conductivity | >0.75 | |
| TDS (ppm) Total Dissolved Salts (Solids) | >500 ppm | |
| Ion Toxicity (Impact on Root and Foliar Contact) | Roots | Foliar |
| Na+ (meg L-1 and ppm) | >200 ppm >9 meq L-1 | >70ppm >3 meq L-1 |
| Cl- (ppm) | >335 ppm | >100ppm |
| B (ppm) | >3 ppm | >520ppm |
| Sodium Permeability Hazard (Impact on Soil Structure) | ||
| Sodium Adsorption Ratio SARw | > 9 meq L-1 | |
| Sodium Adsorption Ratio Adjusted SARw | >10 meq L-1 | |
| Residual Sodium Carbonate | > zero | |
| Nutrients (ppm and meq L-1) | ||
| PO4- | <0.30 or >2.42 ppm | |
| P | <0.10 or >0.80 ppm | |
| K | < 5 ppm | |
| Ca | < 20 ppm | |
| Mg | < 10 ppm | |
| SO4- | >180 ppm | |
| S | > 60 ppm | |
| NO3- | < 5 or > 100 ppm | |
| N | < 1.1 or > 22.6 ppm | |
NOTE: Key basic information should be requested from analytical laboratories when submitting samples for analysis. Because SeaIsle 1 will often be grown in salt-challenged environments, knowledge about the level of salinity stress will be extremely important for making management decisions. |
