Irrigation Calculator
 

Gaia College provides this on-line calculator free of charge for irrigation scheduling purposes.

The effective application of any tool depends on the knowledge and experience of its user. The proper use of this calculator and interpretation of the results are described in the Organic Master Gardener or Organic Horticulture Specialist courses. We strongly suggest that those without prior training in irrigation scheduling participate in one of those programs.

The responsibility for use and application of the calculator rests entirely with the user. Gaia College assumes absolutely no liability for any use or application of this irrigation calculator.

Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/gaiacol/www/www/irrigation_calculator/footer_how.php on line 21
