I mixed my soil togther with 1 cup of blood meal(12-0-0), 2 cups of Bone meal(2-13-0), and 2 cups of dolomatic lime in a 20 gallon rubbermaid container. Now that i have my N-p, what can i use for k? Can't seem to find green sand or kelp(not liquid form).
wood ash is very high in potassium(K) and has some other micros as well.
But Wood ash would increase the ph of the soil. Any other suggestions?.
the wood ash will just take the place of the dolomatic lime.
"Field and greenhouse research have confirmed the safety and practicality of recycling wood ash on agricultural lands. It has shown that wood ash has a liming effect of between 8 and 90% of the total neutralizing power of lime and can increase plant growth up to 45% over traditional limestone." http://hubcap.clemson.edu/~blpprt/bestwoodash.html
