Simple Steps to Irrigation Scheduling Using the "Look and Feel" Method
Franz Niederholzer & Lynn Long

You will need to determine the rooting depth of the tree or plants to be irrigated, and the soil water-holding capacity of different soil horizons within the root zone of the plants to be irrigated.

Use these instructions for getting a soil sample to get started.

Information Sheets

Once you have a sample to look at, use these sheets to help you determine the soil moisture content of your soils by comparing your sample to the photographs on the information sheets.
