Irrigation Water Analysis
Enter your borehole or irrigation water test results to check them against the official South African Agricultural Water Quality Guidelines -- crop yield risk, soil sodicity, equipment scaling/corrosion, and drip emitter clogging. Scan your lab report to fill the values in, and pick your crop (grapevines by variety and rootstock) for a crop-specific check.
