It can be used right away. I have goats and it works great! Other manure like chickens, cows and horses burn the root system.
It doesn't need to break down. But if you want it to it takes a few years unless you crush it up :)
Horse manure needs to compost for 1 year to be safe for use around human products like food. If you do not compost the manure, it will take far longer for it to decompose naturally.
The amount of time it takes will depend on how often the manure is turned, what type of bedding was used, and the nitrogen content of the manure pile. It should however take about four to six months to break down, although if it is intended to go onto a garden where food will be grown it needs to be composted for about one year before use.
Depends on the amount of manure.
it takes 20 years approximetly to break down.
Horse manure can attract fleas if left out for too long. It is best to clean up the manure before too long to avoid this problem.
The water will not ever break down. You will need to remove it.

Plastic takes a long time to break down.
