Great Info Bill, I do the tea with Rabbit Manure in the Spring.. Summer I just sprinkle a handful around the base since the tea...well...itll knock your socks off haha. Veg beds get filled up all winter as does the compost bin.
Anyways if you think its Nitrogen, Its a good solution. Highest in Nitrogen you can get from Live Stock, Cheap or Free, Not messy, and its a cold manure. Can you tell I love it??
