Best thing to do is once your plants are done, or a frost knocks them out, pull the plants out. Depending on the plant you may want to take the leaves off and throw them in the garden, as they are organic material. Turning over your garden to get rid of the excess weeds and roots is a smart idea too.
After you're done with that, get some groundup leaves from your Fall cleanup, and plop them on your garden and spread them out. A good layer will again, add organic material to the dirt to "recharge it" and add a barrier for extra weeds, etc during the Winter months. I dunno where you live, but as the Winter progresses, the leaves will break down, especially when the snows come.In the Spring, turn over your garden, mixing the groundup leaves into the soil, add more dirt if needed (I HIGHLY recommend Miracle-Gro's garden soil), and get planting!
I start my seedlings, say broccoli inside in Jan. They go out towards the last part of Feb, here in zone 9 you have to provide frost or freeze protection which I use in the form of a cloche. Fancy name for a plastic gallon milk jug with the bottom cut off.
With the seedlings inside, the ground is turned and mulch, compost and sand is worked into the soil. When these seedlings are put out into the soil, all the nutrients are there, just waiting for them.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
