I don't claim to be a scientist or even an expert, but I've picked up a thing or two over the years.
When I took my master composter classes, they claimed that coffee grounds were actually "green" according to MSU literature. That raised a few questions in class. The short answer was that the small amount of coffee grounds added to compost or soil was only a short term response. Soil structure and composition developed over thousands of years and what we do is merely short term. That makes sense to me.
I've posed similar questions to the professors in the biology department and not one of them can provide an answer. They suggest going to the geology department and ask there. Trouble is, we don't have a soil science expert on campus. Geology profs say they use MSU for soil analysis. It seems to me that there should be more interaction between the disciplines of science. Perhaps some day.
For now, a soil test is less than $20 from your Extension office. Or if folks like, I can get soil pH metres if anyone wants to do spot tests. I can have them at Chickenstock.
So... I grow a diversity of things, and usually just throw lots of different things into the compost and soil, turn it all together, and hope for the best. I feel like I would have to test my soil every few feet for any sense of accuracy, and I am not terribly keen on altering the soil specifically for each one of hundreds of different types of plants. I rely on crop rotation and symbiotic relationships. What I am saying, I think, (because who knows, really?) is that while I would like to test and have the best type of soil for each plant, it seems pointless unless I were to do a lot of soil testing, and invest quite a lot of money.
Sorry, I was up all night with a fussy baby, and then 4 y/o decided to wake up hours early, and wake her baby sister up as well, so I have been stumbling around trying to take care of everyone and get done the things what need doing in a haze all day. I've had a pot of coffee and a few double shots of espresso by now, which haven't managed to wake me up, so if I make little sense, that's my excuse.
