I have unused calcium tablets (100 of them) and would like to use them on my vegetables which are seedlings at the moment. I am on a learning-curve using a new greenhouse tunnel to grow some vegetables, like lettuces, tomatoes, basil and parsley because of the very hot summers in Adelaide. I would look forward to your response. Oh, yes, we are working with clay soil to which we have just added pulverized cow manure and soil amendment. Thank you. Lori.
Can I Use Calcium Tablets Caltrate to Fertilize Vegetables?

Calcium is important for all plants but the following are especially responsive: apples, broccoli, brussel srouts, cabbage, carrots, cauliflower, celery, cherries, citrus,
melons, grapes, legumes, lettuce, peppers, potatoes and tomatoes.
I would not add any calcium until you have done a soil test. Since you are amending clay soil with compost and other materials a soil test will help you determine what is missing or not from the soil mix.
Here are some links to help you.
