My friend and I are preparing 4000 feet of garden space with sheet mulch. We are hoping to jump start the soil since we only have 2 years untill we finish high school. Right now we have 4000ft^3 in leaves, 13 bales of wheat staw, 4000 feet of cardboard (oh Duke of permaculture please forgive us sinners), alfalfa meal, and the previous year's leaf compost to get a little microbial action goin. The plan:
1 layer of cardboard thick enough to suppress the current growth
Then a thin layer of Nitrogen for balance
12 inches of leaves
Completed leaf compost to speed up decomposition
More nitrogen for balance and finally a layer of straw mulch to keep in moisture and shelter the bacterial decomposers from the sun
First off, is this a recipe for success? Second, is there any way that we can verify the wheat straw is herbicide free? We would appreciate any help we can get! Thanks
