I have to admit that I have never grown any plant edible or ornamental but I once met a dude who said that fertilizer is necessary to grow food and there are two sources: animal types such as their poo or blood & bone that comes from slaughterhouses or there is chemical fertilizer that if you use means you are not growing organically. I was thinking that since old growth forests have existed for thousands of years without ever being fertilized, why do you need fertiliser to grow food?
