| Abstract/Contents: | "Several weather based smart controllers at Berthoud, Colorado were programmed to manage six virtual landscape zones over the 2015-2016 seasons. These virtual landscape zones covered a wide variety of soil types, plant materials, and irrigation methods but were the same six landscapes given each controller. The zone valve control outputs on each controller were connected to switches/relays monitored by a data logger which recorded the minutes of runtime for every irrigation cycle of all six zones on each controller. Controller performance was obtained by importing these irrigation events into a daily soil moisture depletion/balance spreadsheet using the dual Kc method for calculating plant water use. The dual coefficient method partitions ET into evaporation from wetted surfaces and transpiration through vegetation. The increased evaporation following rain or irrigation events and the reduced transpiration resulting from soil moisture depletions were calculated day-by-day for the both the controller determined and the 'preferred' watering for each zone. Both were calculated using the same spreadsheet. Controllers able to water deeply but less frequently to meet plant needs and/or that directly account for onsite rainfall compared closer to the 'preferred' watering needs than those which did not." |
