Is soil depth an important consideration affecting irrigation?

Gardens & Landscapes October 04, 2011 Print Friendly and PDF

Yes, soil depth determines the potential rooting depth of plants to be grown and any restrictions within the soil that may hinder rooting depth. One crop may require 3 feet of soil, while another may require 4 feet. Any discontinuities in the soil from layers of sand, gravel, or even bedrock can physically limit rooting depth and hinder irrigation. It can also create problems when using irrigation.
