Since poop is the solid waste that the majority of organisms produce, how is it so packed with nutrients that plants like?
In: Biology
A lot of the elements inside the plants that we eat doesnt get fully absorbed by the digestive system, and it passes through us as feces. Plants actually require these elements to grow. Using poop as plant fertilizer completes the cycle. Its actually a huge problem in agriculture that we dont use sewage as fertilizer and just throw those elements away, and use mining or chemical synthesis to make fertilizer. The main reason we dont use sewage fertilizer on an industrial scale is because harmful bacteria could get on the food, and also sewage has small amounts of pharmaceuticals and who knows what else.
