  Paper cited suggests 164K km^2 (about 40 million acres) of total turfgrass. USDA estimate for corn crop in the US is almost 92 million acres. Note that the paper claims that turfgrass is 3x larger than the largest irrigated crop, not that it's larger than all crops. Only about 20% of US corn is irrigated (~80% is rain watered only).
