Fertigation in a sugarcane agroecosystem (In extenso)
A fertigation system designed in the Postgraduate School Campus Veracruz was evaluated. The aim was to validate this low pressure system with multi-gates pipes using a Venturi-type injector in an agroecosystem with sugarcane. The uniformity with which the orifices of the system emit the nitrogen fertilizer at fertigation was evaluated, as well as the stability of the system. The experiment was carried out on a 1.5 ha plot with sugarcane. Three factors corresponding to the different openings of the valve were tested to see their effects on the homogeneity of the fertigation at the outlet of the pipelines gates and the stability of the system respect to time elapsed. Samples of water-fertilizer mixes were taken at the exit of the pipeline outlet and analyzed in the laboratory with a Visible UV spectrophotometer. It was identified that for some valve openings the system is unstable. For 2/3, there was no significant difference at the time of emptying the container with fertilizer. Therefore, it was concluded that at least valve openings close to 2/3; this system behaves stable. In response to the experiment, it is partially concluded that, by correctly regulating the amount of water-fertilizer that enters the system, a uniform mixture is obtained at the outlet of the orifices of the pipe that pour said fertilizer into the rows of the crop.

Se evaluó un sistema de fertirrigación diseñado en el Colegio de Postgraduados Campus Veracruz. El objetivo fue validar dicho sistema de baja presión con tuberías multicompuerta utilizando un inyector tipo Venturi en un agroecosistema con caña de azúcar. Se evaluó la uniformidad con la que los orificios del sistema emiten el fertilizante nitrogenado al fertirregar, así como la estabilidad del sistema. El experimento se llevó a cabo en una parcela de 1.5 ha con caña de azúcar. Se probaron, tres factores correspondientes a las diferentes aperturas de la válvula para ver sus efectos en la homogeneidad de la fertirrigación a la salida de las compuertas y la estabilidad del sistema con respecto al tiempo. Se tomaron muestras de las dosis de mezcla agua-fertilizante a la salida de las compuertas y se analizaron en laboratorio con un espectrofotómetro UV Visible. Se identificó que para algunas aperturas de la válvula el sistema es inestable. Para 2/3, no hubo diferencias significativas en el tiempo de vaciado del contenedor con fertilizante. Por lo anterior, se concluyó que por lo menos a aperturas de la válvula cercanas a 2/3; este sistema se comporta estable. En respuesta al experimento, se concluye parcialmente que, regulando correctamente la cantidad de agua-fertilizante que entra al sistema se obtiene una mezcla uniforme a la salida de los orificios de la tubería que vierten dicho fertilizante a los surcos del cultivo Colegio de Postgraduados 2022-12-12 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://agrodivulgacion-colpos.org/index.php/1agrodivulgacion1/article/view/121 10.54767/ad.v2i6.121 Agro divulgación; Vol. 2 No. 6 (2022): NOVIEMBRE-DICIEMBRE Agro-Divulgación; Vol. 2 Núm. 6 (2022): NOVIEMBRE-DICIEMBRE 2954-4483 spa https://agrodivulgacion-colpos.org/index.php/1agrodivulgacion1/article/view/121/118 Derechos de autor 2022 Agro-Divulgación |
