Interpreting Soil Test Lab Results & Plan of Action
I had my soil tested and per the lab most things look decent. All the micronutrients are normal. Here are the rest of the results:
Soil pH 7.4
Phosphorus (12ppm) Medium
Potassium (19 ppm) Low
Calcium (1191ppm) high/very high
Magnesium (206ppm) very high
Cation Exchange: 7.7 Meq/100g
Percent Base Saturation:
K=0.7 Mg=22.0 Ca=77.5
Extractable Aluminum: 5ppm
Soluble Salts: 0.06 dS/M
The lab recommends 6lb potassium/1000 sq ft along with 1 lb of nitrogen.
Do I need to be worried that my calcium and magnesium is TOO high? Theres no information on how to interpret those "very high" ratings. I've tried googling but just came across a bunch of stuff about whether or not there is an "ideal" Ca:Mg ratio. Should I be looking to bring down the pH to be a bit more acid? scatter coffee? something else?
