A Precision Sprinkler for Soil Moisture Studies
Two types of systems were investigated: An overhead sprinkler arrangement and a portable, motorized system. The overhead sprinkler system was rejected for several reasons. Rotating or oscillating fixtures could not be used because of the amount of drift expected from strong southerly winds common at the nursery. Fixed nozzles on short, individual risers would not be as affected by wind but would be too expensive. Complete coverage would have required many risers. Spray patterns would overlap, making distribution uneven. The risers would prevent the use of nursery equipment within the plots. The portable motorized system (fig. 1) met all requirements. The system consists of two parts: (A) The boom unit, and (B) the control-power unit.
