Use of Horse manure
Good People- I have access to an unlimited supply of mostly dry horse manure or cow manure. I am told that horse manure is better for vegetable or flower gardens in that it will not "burn" plants much at all. Assuming this is true, I expose my ignorance by asking the following:
1- Is it safe to eat fruits and vegetables that have been fertilized with horse manure?
2- If so,when, how often and how much should be used, especially when used in a vegetable garden?
BTW, this stuff is very dusty when being shoveled-especially in a barn. Is it very harmful when breathed?
Grateful for any reply
