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?
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?
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.
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.
