Risk - Down

Tile drainage reduces surface runoff and soil loss, and allows farmers to use less tillage. “Many fields would benefit from tile to decrease channeling and ponding,” Frame says. Older concrete or clay tiles often have cracks or leaks that leak significant amounts of sediment and phosphorus, he says. The same is true of systems with open surface inlets. Older tile systems may also have undersized mains that limit drainage capacity. “So we need to update our older tile systems.”
