"Considerably, a new subject, fertigation is the application of fertilizers, soil amendments or other water soluble products, through an irrigation system. Fertigation is used extensively in commercial agriculture and horticulture and is also now being used in general landscape applications, as dispenser units become more reliable and easy to use. Because of the potential risk in contaminating the potable (drinking) water supply, a backflow prevention device is required for most fertigation systems. Chemigation, a relative and sometimes interchangeable term, is the application of chemicals through an irrigation system. Chemigation is considered to be a more restrictive and controlled process, due to the potential nature of the products. Fertigation is an applied subject, under agricultural sciences. This painstaking and research-based work is a valuable addition to a few books on the subject." (jacket)
