Protocols

Soil Moisture-Based Controllers

SWAT Testing Protocol

Version 3.0 of the protocol was approved and adopted in August 2011. Phase one of the protocol tests the performance of the soil moisture sensor and phase two tests how well the controller schedules irrigation events.

Notes: Soil Moisture Sensor Meeting, Jan. 15, 2008, CIT, Fresno, Calif. Representatives from 12 soil moisture sensor manufacturers met together with water provider representatives, SWAT committee representatives and IA staff. The goal was to jointly advance the development of the proposed draft protocols for testing of individual sensors and how effectively they control irrigation events.

Phase 2, Draft 1: Test Protocols

The Phase 2 first draft test protocol began to address the "Outdoor Operational Test on Turf Grass," which integrates the soil sensor with an irrigation controller to measure irrigation adequacy and efficiency in a virtual landscape.

Phase 1, Drafts 1-4: Test Protocols for Indoor Lab Screening Tests

Key development of Phase 1 protocols took place in the first through fourth drafts. Phase 1 beta testing began at the fourth draft of the test protocols. The objective of Phase 1 lab tests is to evaluate how well current soil moisture sensor technology functions over a range of conditions that affect soil moisture, including soil type, temperature and salinity. Phase 1 Soil Moisture Sensor testing results do not measure the integration of a soil sensor with a controller to manage irrigation.
