Adding manure before tilling
I always till the veggi garden in the spring before planting but I'm wondering this year if it would be ok to till in some manure from my horses or chickens? I won't be planting anything probably at least for a month here in michigan. I know composting is ideal but I didn't do that. Also, can I till in some straw that I received with my hay shipment? My soil tends to pack so I was hoping to lighten it up a bit.
