I'd like to know more about this too. My chicken pens are built around the edge of a paddock that is mostly chalky fill material and which used to support a fine growth of bermuda grass. In addition to the pens (which the chickens keep bare) I keep a few tractors in the paddock. I used to be able to move the tractors when the grass inside got brown & bare, and new green grass would grow back within a few weeks. But recently I noticed the grass was taking longer to re-grow, and some places stayed bare. Then last summer there was a period of heavy rain, the paddock flooded, and it's getting more bare with less grass growing.
Our ground in South Florida is very alkaline, but I think the chemistry of the accumulated poop has finally overwhelmed it. Last week I spread pelletized lime around the bare paddock one evening after all the chickens were in their coops. I watered it in and the next day the chickens were back out on it. None of them seem to be adversely affected by it.
Do you think this lime will help the grass to grow back? Will it also help kill any bad bird cooties in the soil?
