(Camp Hill) -- Midstate farmers' profits could take a hit as extremes in weather lead to possible crop damage and lower production. A very wet spring held up planting for many central Pennsylvania farmers. Now hot and dry conditions are stunting crop growth, which could lead to a loss of revenue for many farmers come harvest time. Pennsylvania Farm Bureau Spokesman Mark O'Neill says sweltering heat also affects dairy production.  "Dairy cows basically don't eat as much when it is so hot like this. When they don't eat as much, they also don't produce as much milk. When they don't produce much milk, then the farmer has less milk to sell. Therefore, he's losing money," O'Neill says. He says farmers who grow grains to feed their cattle are hit twice by the dry weather, as they may have to purchase feed for their herd. He says there are also concerns farmers may not be able to recoup the cost of things like fertilizer and fuel needed to keep their farms running.
