Raízen reuses by-products from the sugar-cane to ethanol process: for instance it sprays a liquid from ethanol distillation onto fields as a natural fertiliser.

Question by Miskiyat Jimba: Is there an organic way to create a fertilizer that also kills bugs?
i have a science project to make and i notice that people don’t want to use fertilizers because they aren’t very organic. is there a way to make an organic fertilizer. and then from there i can use the organic pesticide that i made to combine it with the fertilizer and see if it works.
THX IN ADVANCE!!! 😀
