soil Bray phosphorus and ph
I had my garden soil tested and have 7.6 ph and 111 phosphorus. My garden is about 500 ft2 and I have added a lot of horse manure(2 years ago) and yard clippings yearly.What is the best additive to lower ph to about 6.8? I live in Sherburne county. The organic mtter was 4.7%. Is the phosphorous nymber too high?
