really, youre not making a compost pile on the plant. all ruminants (goats, lamas, sheep, and the like) and rabbits can be put on your plants for fertilizer without it burning it. This is well known. As soon as it comes out of the animals behind, it can be used on the plant. Horse/cow/chicken will burn it. Do your own testing and do some more research. We raise goats and for the last 10 years we have been using it fresh without any ill effect. I put a layer of hay and poop (barn cleanouts) over the top soil about 4-6 inches deep. I do this at least once a year. You can tell the difference. I have done plants with manure and without manure side by side. It is clear. I also use the tea with excellent results.
So to those people who want to try the manure approach, I highly recommend it. It's way safer and healthier to you than chemicals. You are recycling and not killing the soil. If you are uneasy, just do a little more research and you will see.
Hope this helps
Also, there is no real smell to it. You don't smell anything when it's applied to the plants. It's when you have a load of it, you can smell it and it's not even bad then. When you are mucking it into a large pile, then it smells. Try it once. If it's too much and feels over the top, then don't do it. Try it first.
