? To what degree do trees self-fertilize by dropping leaves and building their own humus ? They capture energy from the sun and nutrients from the air (and soil) and some of that production feeds the soil upon which the following year's growth depends. The soil biota processes the wastes, further captures atmospherically-deposited nutrients, and makes it all newly available for further growth, I would imagine. Apologies for being a marine biologist but this seems like something that might have been researched already. Yes or no?
