With fertigation, fertilizers can be applied with irrigation water on demand during periods of peak crop demand at or near the roots and in smaller doses, which ultimately reduces losses while increasing yields and quality of product (Tilman et al. 2002). If properly designed and scheduled and also taking into consideration soil properties (Gärdenäs et al. 2005), fertigation systems allow for the more efficient application and use of nitrogen (Singandhupe et al. 2003; Hou et al. 2007) thereby reducing its leaching and runoff.
