ASAE/ASABE S623

This methodology will provide an estimate of plant water demands of permanently installed, non-production based, established landscape materials. The standard will provide minimum water demands for acceptable plant appearance and function. This standard does not cover plants for sports fields, golf courses, or food production. This methodology is applicable for planning and design of planted landscape areas as defined in section 3. It is assumed throughout this standard that the soil around the plants in question are wetted uniformly by precipitation or irrigation.
