1/4 c per 5gal bucket - put it in the hole, then a several fistful of lime, cover with soil, top dress with lime, water. I normally do this twice a month.
Truthfully, I see no difference. I fertilize with dyna grow pro. I use hp promix w/ fungicide, and heavy on lime. Both work
awesome soil, good drainage, compost, age manure, lime, perlite, and sun = happy figs
Best of luck
