With regard to farming, what do you think is the best use of chemicals and why?

Explanation:Organic farmers are different from conventional farmers because they choose not to use any chemicals on their farm. This means that they never spray their fields with pesticides or spread any kind of chemical fertilizers. This also means that they never give their animals any non-organic feed or give their animals any drug past a certain age. For a farmer to be able to sell his product as certified organic in Ohio, the soil must have been chemical-free for at least four years. However, it varies from state to state. While in California your soil only has to be chemical-free for one year in some states it may have to be chemical-free for ten! Each organic farmer has his own reasons for choosing to farm organic. Some farmers do it because they feel that it is cheaper to farm organic. They don't have to pay for the chemicals, they get higher prices for their products and they can use a crop rotation to produce the same kind of crop yields. Other farmers do it because they feel that they are producing a healthier product. Most farmers choose to farm organic for a combination of those reasons and others.
