The AM400 is an inexpensive yet powerful irrigation scheduling tool that can improve the grower's bottom line. By helping the grower make better irrigation scheduling decisions, the AM400 can increase crop yield and quality while reducing water, pumping, and fertilizer costs. The unit also offers a range of environmental benefits including reduced groundwater contamination and run-off.
Operating on two AA batteries, the AM400 automatically records readings every eight hours from six Watermark(tm) soil moisture sensors located up to 1000 feet away. At the push of a button, the grower can view soil moisture graphs generated from the recorded data on the AM400's built-in graphic display. The displayed graphs make it possible to quickly determine soil moisture levels and trends at selected locations and soil depths.
When more detailed analysis of soil moisture data is required, ten months of soil moisture and temperature readings can be downloaded to a notebook computer or PDA. Downloaded data can be imported into a PC spreadsheet program or graphed directly using the optional AM400 Chart graphing software.
