An engineer came to you to discuss their design of his application rate for a land application system and wanted your input. During the discussion and showing you the water balance as described by the TCEQ method that the maximum application rate prescribed during one month (August, 31 days) was 8 inches and they were using a center pivot irrigation system that covers 180 acres, which covers both the crop water requirements and leaching. They informed you that the pumping system was quite good in that it could supply 800 gallons per minute to the irrigation system. How would you respond to this engineers' design numbers
