Hello, I am bugged by a thought and hope that somebody will be able to help. I have started a vegetable garden and would like to use vegan-friendly fertilizer i.e. manure, but I read an article in a scientific journal about mass production of manure using cruel methods (did you know that 'producing' manure can be quite painful for cows, especially after giving birth?) so was going to go for chemicals but those are not good for the planet and the animals either... please help?
