Sengsational,
I am a organic gardner and make my own compost and use bonemeal, blood meal and epson salt for organic fertilizers.
My garden area was originally around 5.7 PH wise, and when I checked it this year is was in the 6.6-6.9 range (3 different raised beds).
I have been mulching with straw for years then in Feb or so would fulff that up and burn it off before breaking my garden.
I think the combination of buring off that straw (ash sweetens soil, raises ph) and using bone meal (bone meal will also raise PH) is what has raised my PH up in that 6.6-6.9 range.
I did not burn it off this spring, I checked the PH first and saw that it was getting a bit higher than I want it and I am going to switch to using gypsum insead of bone meal for the next few years to boost calcium.
I expect that eventually it will get back down in the 6.0-6.5 range (where I want it to be).
When I plant my tomatoes I add a about 3 table spoons of bone meal (using gypsum now), and about a tea spoon each of blood meal and epson salt and a couple shouvel fulls of my home made compost and man they really grow big and stout and last until fall making maters
Bonemeal is a good source of calcium and phosphorous, but the draw back is it will raise PH so you should only use it if your PH is lower than your target.
Bloodmeal is a good source of nitrogen - not sure how it might affect PH. I don't use much of it on tomatoes. If you do you will get lots of vine & leaves but not a lot of maters.
Epson salt is magniseum sulphate - a trace mineral that is important for long life - healthy plants. It will help your tomatoes keep on producing late in the year.
I have found that I better chain up my daughters shepard dog or she will go after that bone meal and blood meal and dig up what I have planted.
After I have watered it in good or after it comes a good rain or two - no problem but when it is fresh in the dirt our dog will sure go after it and dig to get it.
