Okay, we must work with both chemistry and biology to get a tangible grip on what is life. May be with a focus on tangible reality, this thread will be managable?
I believe I killed many seeds, by trying to rush sprouting. I soaked them in water and then let them dry out, because I decided the seeds where too small to sprout that way. Now they are planted in soil and won't sprout. Conclusion I killed them, and this must have something to do hydrogen. Right?
"What seeds are we talking about? How have those seeds been conditioned to germinate in nature. Ie. native prairy grass seeds wait for the heat from the grass fires to germinate. I do not think hydrogen or nitrogen deficiencies will stop a seed from germinating but instead will affect the plant as it grows."
Some of my soil is very woody, and this depletes nitrogen, which is need for growing plants. Right? What is happening here? Why would wood deplete nitrogen and why must plants have it?
"Lots of things in the soil deplete nitrogen - But i don't think wood or woody material will."
Next question, why is it so easy to kill the plants we want, and so hard to get rid of the plants we don't want?

Seriously- may be understanding this, will improve my ability to get desired results.
"If an apple tree is left on its own, it will produce lower and lower quality apples each season. probably fewer apples as well.- the plant quality will migrate to a downward level.
It takes an outside stimulus to trim the branches, removing suckers and misplaced branches to keep the plant on a sustained quality level. This trimming produces a stronger plant and better apples by raising the plant quality level. The plants you want are already raised to a high level and so it takes extra effort to maintain them at that high level. Where as the plants you don't want are at a basic low level and so very little will bother them making it hard to get rid of them."
I am restricting this to plant life, to keep it comprehensive. After I get a grasp on what is happening with plant life, then I want to tackle animal life. You all have taught me a lot and really appreciate you.
