Granulated Calcium Phosphate & Dicalcium Phosphate

Question

are the 2 nutrients marked above beneficial to already growing plants if sprinkled in the soil? my garden soil isn’t the greatest, and i’ve been burying fresh vegetable remains, coffee grounds, dead autumn leaves, plant/flower cuttings, eggshells (and “eggshell soup” for the past 2 years to improve it. crops are much better this year, and the worms have increased magnificently. so how about the extra calcium? will it hurt or be beneficial? i have about 8 pounds here—–a gift from an animal farmer friend.

Answer 1

That will depend on what a soil test says. If there is already enough calcium in the soil, then it would be a bad idea to add more. However, if the soil needs calcium, then it would help.

The best way to know, for sure, will be to test.

Here is an article that will help you to do so:
