Organic farming

Today I am going to talk about a very simple test that we did in our university with my friend we were doing a test about organic farming. We did cultivate tomato using the brown alga as a fertilizer and we did cultivate other explants with chemical fertilizers to see the difference between them and we find that there was not a big difference by calculating the concentration of the chlorophyll a,b.And carotenoids of the explants of the tow test in three months ,like that we could say that the brown algae are not riche of Azote but if we use other   species with them we could have a very nice results and a way to prove that the organic farming could be a way to protect our earth and have bio products that are good for our health .
