How do I take top soil from one place add nutrients, Cow, horse, and chicken manure, Also straw and crop residue. With out ending up with a bunch of weed seeds in it. I have had to buy alot of soil to put in gardens and raised beds and I need alot more.
We have a ragweed, cheat grass, red root, and sticker problem. As well as the dred Russian thistle. I live in Southwest Nebraska and our soil is like 90% loess with four inchs of top soil. I am not afraid to use water fire or diesel power to accomplish this. No money though I haven't got any of that stuff.
Redhawk is the expert here, but in my experience the only problems I've had with thistle and other invasives came out of horse manure. So I avoid that now and just use chicken manure in my compost. (eastern city girl, no experience with your weeds or cow manure :)
I have seen a lot of people lay down tarps (or a similar dark colored covering) over soil once it's in place in the garden bed to do this. The tarp traps the heat in the top of soil, killing seeds and smothering weeds.
That is mine thank you. Thank you guys for your replies. I think I'm going to smother a bunch of stuff. I get alot of tarps from the corn binkers at work. Interesting side note we have a compost pile there that is so N rich it started stuff on fire when they started pushing off the hill side. Weeds will try to grow in it as soon as it rains they get fried. I would use it but for the Roundup and atrizine. I think I will also start hot composting.
I love these forums this place is a treasure trove of how to and it seems like a very nice community of people also.
hau Zach, why not use that "compost" as a starter for a good compost heap, if you add fungi, the nasties will be broken down by the time the hot heap has cooled. If you would like exacting methods to do that, let me know.
