    I have prepared two natural farming inputs WCA (Water soluble calcium) using calcium carbonate from oyster and egg shells and WCAP (Water soluble calcium phosphate) using charred animal bones.

    Both inputs use a vinegar as the acid to chelate the minerals.

    In the past I’ve used dolomite lime during flower applied topically around my tomatoes to avoid blossom end rot. I applied worm castings at the same time and so the increased yield and production I attributed to the worm castings.
