Looking forward to future crop nutrition, the health of the soil is paramount. Chemicals will ruin the soil [hence needing more chemicals], whereas organic crops enrich the soil.
What DonQ said, yup.
Also, if they had tested some of the more well-known "organic is better" crops, the would have found nutrition is better in the organic crops. Bananas, for one, have 3 times the nutrition of a chemical crop banana.
HEY! Why are "chemical crops" called "conventional" anyhow? Why doesn't "conventional" refer to the original food we ate for 100s of 1000s of years? [free of chemicals].
