Open field fertigation consists of providing water and mineral elements to plants on a regular basis, in limited and calculated quantities. Through its supply of water and minerals located near the roots of the plants via an injection system in the drip irrigation tubing, fertigation makes it possible to obtain great efficiency in the use of water and fertilizers (notably by a reduction in leaching). Fertigation is the most efficient method for producing more with less.
