Best way to add calcium?
Besides eggshells ?
I have been having pretty dismal tomato growing seasons the past two years and while I know it has been partially due to the lousy weather here (extremely rainy/cloudy) I think it's my soil too. I am going to get a new soil analysis soon but I am sure I am low on phosphorus and potassium, so I purchased rock phosphate and rock potash to amend my soil with. But I'd like to add good calcium too and I dont have enough time to collect enough eggshells (dont eat that much egg) until growing season starts. Any suggestions?
