Horse manure mixture

A question from a fellow grower:

I would like info on organic outdoor growing. I like to use compost made from my horse manure mixed deeply into soil fall and spring. What is the maximum I should be adding to this?

That is hard to say. If you alre4ady practice this, then I would say mix it in as you would for Tomatoes. On the other hand; I am not really sure what you are describing that you want to do, and if not careful Horse Manure can be way too hot for some plants and will burn them up. Manure has to be blended into the soil over a long period of time in order to allow it to cool down, and become ammended into the soil.
