Soil farmer Geoffrey here, in North Central Arkansas. My family introduced me to manure tea production decades ago. Available skat was mostly bovine. I have progressed to produce manure tea today from a local dna dedicated bison herd. Teachable to adding local flora in the near future. Overall soil improvement. Progress not perfection.
Hope to read your book after humbly winning one from the sponsored contest. Either way, the soil constantly improves.
Encouraging in Arkansas,
Geoffrey Nielson
