Recently I have been hearing claims that food grown using "natural fertilizers" , such as manure, decayed plant matter, decayed food materials, are somehow superior to foods grown using inorganic chemical fertilizers. Nothing can be further from the truth. Plants which derive nutrients from the soil and water end up having to extract and convert the nutrients and materials in "organic fertilizers" to the same nutrients found in inorganic chemical fertilizers. To the plant both are the same.
So, about the only thing different between "organically grown food" versus "non-organically grown food" is the price, the former generally being more expensive. Organic food ? Nice but not necessary.
