APPLICATION TECHNIQUES OF FERTIGATION
(Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2013) Cetin, Oner; Uzen, Nese; Karaer, Murat
Advances in micro-irrigation techniques have facilitated greater adoption of the application of fertilizers to crops through irrigation water; the technique is termed as fertigation. Fertigation is used extensively in commercial agriculture and horticulture and is starting to be used in general landscape applications as dispenser units become more reliable and easy to use. Some irrigation systems offer the ability to use high-frequency fertigation likes drip irrigation systems. Irrigation and fertigation system design, soil type, crop stage, chemical type, fertigation time and irrigation water quality are important parameters for an appropriate fertigation. Fertilizer application techniques are also an important factor in achieving success. All techniques for incorporating a chemical with the irrigation water create a specific level of chemical concentration during irrigation. The various techniques may be classified into three main groups. These are; (i) gradual decrease of chemical concentration, (ii) constant level of chemical concentration, (iii) intermittent chemical concentration. In this article, the methods and equipments of fertigation and some research results of the fertigation frequencies on crops are presented.
