Hello, I am new to the forum and this is my first posting. I have a question regarding the addition of manure to the vegetable garden. Last fall, we added about 5 cans containing about 30 gallons each of horse manure to our 16x24 foot garden. I also added ground leaves from the yard. This spring I tilled the soil. This year's yield was incredible compared to past years. My question is whether to add more manure and how much. My wife and I are debating about how many of the nutrients are still present in the soil. On one hand the manure did wonders for the soil. On the other we don't want to burn next years veggies by over-fertilizing. Any input will be greatly appreciated. Thanks, John
