To see how quickly an investment in irrigation can positively impact your operation, enter real numbers from your farm into this calculator. All rights reserved. The uniformity of water application under a center pivot is determined by setting out cans or rain gauges along the length of the pivot, bringing the irrigation system up to proper operating pressure, and letting the system pass over them. While the system capacity is critical to supply the peak crop water requirement, it also determines the operating hours necessary in normal conditions. Generally, radius equals machine length plus endgun throw (if present). The calculation for water loss and water used by the crop is: ET p K c = 0.5 1 = 0.5 inch per day. 8463 0 obj <> endobj Click on the dots to learn more about Agrico centre pivots.
