Nearly three quarters of US farmers say this year’s drought is hurting their harvest — with significant crop and income loss, according to a new survey by the American Farm Bureau Federation, a lobbying group that represents agricultural interests.

This year’s drought conditions are taking a harder toll than last year’s, as 37% of farmers said they are plowing through and killing existing crops that won’t reach maturity because of dry conditions. That’s a jump from 24% last year, according to the survey.
