I imagine that farmers' high rate of gun ownership and social isolation are the big factors. It's pretty well documented that people with guns are more likely to successfully take their lives when compared to suicidal people who do not have guns. Couple that with the fact that there is not really a support system or general awareness of this issue and you have a problem. Veterans are also likely to own guns, but at least they have the VA and other organizations that are readily available to help in the event of emotional or psychological issues. Farmers do not have an equivalent organization.
