I have always been told that wood ash makes the ph higher (alkaline). For several years we have put our wood ashes into a large dog house for my fowl (chickens and ducks) as a dust for them to keep critters off. A tree limb fell on the dust house and destroyed it (no fowl injured).
I was walking around with my dad today and we were testing the soil PH (since it was damp). The soil is usually between 6.0-7.0 . In the area where the dust house once stood the PH of wet ashes was below the zero marking and the surrounding soil 3-4 ph. How can this be?
I was using one the cheap probe meters which I know isn't very accurate but, it does give a rough estimate and does work because I put some aluminum sulfate on my hydrangeas and the ph on the meter went from 7.5-5.8 and What is the scoop? Are ashes alkaline or acidic?
From another site
"In addition to its value as a substitute for lime and macronutrients, ash can also supply significant amounts of sulfur,
boron and other micro-nutrients."
Sulfer lowers PH right?
lol experts help.
