I have a few questions about soil mixing, how to make a safe fertilizer, and if top mulching is safe. I have sand and silt that I gathered from in from of a glacier in Alaska, if I was to make a soil; would it benfit from this silt? I know its loaded with damn near everything. Would a small spoon full in a few gallons of water provide anything good? How long to the benefits of chicken shit, mixed into soil last for? Or any other compost? Do nutrients leach out quickly or is it pretty well sustainable on its own? Im poor but have access to everything from crab shells to kelp, well composted chicken shit, to composted garden mass. Any of these be good to create a liquid solution? I read some on teas. Is top mulching safe? I keep imaging mold problems. Should I imagine mulch acting like an extra inch or two of dirt? I would be mulching with ocean debris. Any one have experience?
