In August, 2008, we moved into our house on a 1/10 acre lot, and I began gardening with a single sheet-mulched plot in the front yard. I took a baseline set of soil tests from the front and back yards in January, 2009 and began a regimen of no-till, no-spray (i.e. no chemical amendments), no-manure gardening, using only plant-based mulch to maintain soil fertility while harvesting as many as 75 crops for market each growing season. The soil tests were done by our local university extension agency.
