VARGAS-RODRIGUEZ, Pável; DORTA-ARMAIGNAC, Abel; FERNANDEZ-HUNG, Kaddiel  e  MENDEZ-JOCIK, Alberto. Considerations for the Rational Design of Drip Irrigation Systems. Rev Cie Téc Agr [online]. 2021, vol.30, n.4  Epub 01-Dez-2021. ISSN 2071-0054.

Now a day, drip irrigation systems are buying with the emitters ''already'' inserted, and introduced in Agricultural farms considering some selection criteria. Based on the data corresponding to real field tests and assuming other suitable parameters, paperwork contribute arguments to bear the obtaining of a rational procedure for the agronomic design of drip irrigation systems. That considers the wetted volume on the root zone as well the depth of the wet bulb according to the root zone of crops and the humidity tension in the soil under the emitters. Particularities of different procedures are showing used for the design of these systems. As a result the convenience is demonstrated of combining the procedures that use the results of the field tests, appropriately the optimal irrigation point and the software that simulate the distribution of the humidity under the emitters, to get a rigorous procedure for the design.
