 {"id": "251", "category": "Irrigation", "context": "Thus, the pivot should operate at a 90% timer setting when the end gun is off and slow to 77.4% when it is on to apply the 30 lbs/acre nitrogen both when the end gun is off, as well as when it is on. The water application will be different - 0.29 inches when the end gun is off and about 0.33 inches when it is on - but the nitrogen rate will remain the same with the constant injection rate pump. The concept behind this method is that the pivot will irrigate the same number of acres per hour, thus the lower cost fixed-rate injection pump will work correctly.", "question": "what should the timer setting of the pivot irrigation system be operating at to apply 30 lbs/acre nitrogen when the end gun is off?", "answers": {"answer_start": [36], "text": ["90%"]}, "references": "Divine, D.
