Good day all,
Below are some values from a recent analysis of well water that I would like to use for my orchids. Some minerals and metals are shown to be at '
very high' levels, and I was wondering if you pros had any insight on how that might affect my plants.
Values in parts per million (ppm).
L=Low, N=Normal, M=Moderate, H=High, VH=Very high
Nitrate Nitrogen: 0.7 (L)
Phosphorus: 0.26 (N)
Potassium: 1.73 (L)
Calcium: 98.5 (VH)
Magnesium: 44.74 (VH)
Sodium: 34.06 (L)
Chloride: 10 (L)
Sulfate: 0.42 (L)
Boron: 0.11 (L)
Zinc: 0.05 (L)
Manganese: 0.04 (L)
Iron: 1.04 (VH)
Copper: 0.01 (L)
Carbonate: 0 (L)
Bicarbonate 579.5 (H)
pH: 7.4 (N)
Conductivity: 0.83 mmhos/cm (M)
Total dissolved solids: 528 (M)
Sodium absorption ratio (SAR): 0.71 (L)
Thank you as always for your expert advice!
