First of all Hi to all, and thanks for any and all advice, I have cleared a spot on a piece of land and built a home. I have 2 acres I have cleared for yard, brought in loads of top soil, at the time hoping to help the soil and area to grow a better grass yard, but more I read I may have hurt it. Anyway I have planted Bermuda, as well as a rye. will adding earthworms into my new lawn or maybe the surrounding areas of the wood lines help enrich the soil with nitrogen? Also are guinnea's and chickens good for my new lawn?
