Landscape Irrigation Efficiency
After a brief overview of soil hydrology – how water moves through the soil and plants in your garden – and a quick survey of different irrigation technologies, you will learn how to properly program your irrigation system for maximum efficiency and plant health. Homeowners typically over-water by 50 to 100 percent. Besides the wasted water and direct damage over-watering can do in your garden, water also carries a large carbon footprint due to the energy needed for infrastructure, pumping and treatment.
