Best Fertilizer
Do you have a particular Best Fertilizer that you use in your Garden?
I was recently watching a short documentary on bats and the presenter said that bath excrement is the best fertilizer in the world because of the prosperities it contains. Baring that, most people seem to use cow dung, but in China I heard it is human waste. I am ignorant about the commercial types available.
Bat, or bird guano is an excellent fertilizer because it has 11 minerals and trace minerals and is high in organic matter. Its major mineral is phosphorus. Chemical fertilizers have only three of the major ingredients needed to have a healthy plant. Cow dung is high in nitrogen and organic matter, but is not an all purpose fertilizer. It's alright if there is nothing else. I have no experience in human waste as a fertilizer. Edited: mousetrails on 25th Jan, 2007 - 3:32pm
Using fungi to decrease need for chemical fertilizers
Plants share their carbohydrates with arbuscular mycorrhizal fungi that colonize their roots and, in exchange, these fungi provide their hosts with nitrogen and phosphorous. By exploiting this relationship, scientists may be able to increase the biomass production of bioenergy crops and the yield of food crops and to reduce the required fertilizer inputs. This could improve the environmental sustainability of agricultural production systems according to researchers. Ref. Source 9z.
