Today I received my soil analysis reports. I've often read that soil testing is helpful, but didn't know where to get it done. This place gives a nice report. It's in an easy to interpret format, and it changes significantly how I plan to amend and build the soil in 2014. Some results are very significant -
My soil is quite acidic. pH is 5.05
I don't need potassium or phosphate.
The soil could use some calcium, magnesium, boron, copper, sulfate, for vegetables.
The report gives recommendations about how to supplement all of the above. I requested organic recommendations. It's somewhat different for vegetables and fruit trees.
The main things -
Nitrogen source, but no potassium or phosphate. Maybe fish emulsion?
Lime, or dolomite lime. That helps with acidity, calcium, and magnesium.
Some Epson salts. That helps with magnesium and sulfate.
Some boric acid. That provides boron. Trace amount only.
Some copper sulfate. Trace, for copper and sulfate.
This is more different additives than I thought. A lot of plants seem to be doing very well as it is, so I'm not sure how important these changes are. Maybe things will grow even better. Some trees had pales leaves - probably the pH. I thought it was low iron, but the iron level is fine.
Nice report. Wish I had that PH. A lot of the things I like to eat require an acid soil. Your PH looks just right for huckleberries, blueberries and blackberries.
I get the idea that it's easier to raise the PH than lower it like I have to do, but I could be wrong.
I should retest my soil. It's been 30 years, although I've used a "home kit" several times. Still too alkaline. Perhaps we could swap half our garden soils? Got a box car?!
