A lot of the stuff I've found on organic gardening can be fit into one of a few varieties: - Why all gardening/farming should be organic: "grow healthier food" - Why all gardening/farming should be organic: "save the planet" - How to do organic gardening: "use bugs not pesticides; fresh manure not fertilizer" - and a very few more
Can someone direct me to a source that will talk more about the science than I've found?
For example: Does it hurt the microinvertebrates in the soil if I add fertilizer? How? If my soil needs some micronutrient (magnesium as one example picked randomly), how can I add it organically? etc.
