If you farm in Washington state, you now have access to irrigation recommendations just about anywhere in the state and at anytime, thanks to the new Irrigation Scheduler Mobile.

The online tool developed by researchers at Washington State University, combines information about soil, ccrop and weather to determine the optimal amount of water, according to a news release.

Irrigation Scheduler Mobile is an interactive website developed with smartphones in mind.

It draws on weather data from AgWeatherNet, the university's network of nearly 140 weather stations across the state.

Users first create a free account, then select a nearby weather station and enter their soil type and crop.

The system will display any water deficit when low moisture levels may damage the plant.

Users also can update their account with the amount of water they applied.

In addition, the mobile website calculates daily crop wataer use, cumulative water use, crop coefficients and root zone depth over time, estimated water lost to deep percolation, and the degree of water stress and estimated yield due to water stress.

A free online demonstration will be conducted at 7 p.m., May 29. Participation is limited to the first 100 to log in.

To participate, you must have a broadband connection and a Flash-enabled browser.
