very low soil pH help
I have been converted to the (primarily) organic way primarily due to my almost year-old daughter and also for the health of the lawn. I did the CGM spring fert, along with a 40lb bag of greensand (my front yard is ~2000sq ft). I did not apply lime since I didn't know its affect on the microbes and also didn't think the soil was extremely bad.
I have a soil test kit that I've been waiting to send out until after all the ferts and additives have been completely broken down for fear of a false reading. But last week I decided to take a single core sample from the center of my lawn (about 3-6" in depth). I left it out overnight to dry, then dissolved it in DI water, filtered it, and then took the pH. I was SHOCKED to see it was ~4.7. My meter was properly calibrated.
I had recently put down a good amount of UCG's from the local starbucks but I was careful that my sampling was accurate and didn't have any grounds in it. I'm now wondering if my lawn really is that low. I will be taking another composite sample from a couple places around the yard, but if it looks similar I think a lime treatment is neccessary.
I'm going to wait another week or two for the purchased soil test sampling since I want to make sure its completely accurate (for the other nutrients), but I'm confident my pH testing is accurate.
