So this is gonna be year 2 of my mulching adventures.
Now i have a bunch of straw with fresh(ish) cow manure/chicken droppings that I cleaned the barns out with over wintertime
Can I till this into the dirt and then throw fresher straw bale over top for mulch?
I know from experience last year that you need extra nitrogen for straw or else things go south quite fast and with a 90 day growing season that's no good.
Is the nitrogen from the cow manure going to be too much for the soil and burn out my plants?
I wouldn't till the straw into the soil as I think that will just tie up the nitrogen already in the soil. You could use the straw and manure for mulch if it's not too fresh, but I'd probably try and compost it first as you don't want to risk burning your plants.. If you have straw without fresh manure I'd use that for mulch instead.
