Agricultural Lime

i add dolomite lime to my garden beds and it does not effect the microbes in there

Be careful! Limestone raises the pH significantly, which causes nitrogen to volatilize in the form of ammonia, which is toxic to people and animals! It’s fine in soil, but in compost or especially in chicken manure, where there’s a lot of nitrogen, it can be dangerous! But after all, why would you want to put limestone on your poultry’s floor? Do you want a fertilizer with more calcium? It’s better to apply limestone directly to your soil.
