DISEÑO, IMPLEMENTACIÓN Y EVALUACIÓN DE UN LISÍMETRO PARA PLANTAS EN MACETA.

Abstract

A lysimeter is a device used in irrigation and cultivation techniques in order to study variations in weight, drainage and water consumption experienced in crop. Lysimeters more widespread in the market are those that are used in land and requires a civil work to install them. Moreover have a certain complexity and considerable financial investment in the installation. However, there are other weighing lysimeters for potted plants while not being so widespread in its use as above and are very useful for the study water consumption of the plant The design have been built and evaluated to place a potted vine (though it may be of similar variety) whose base support is located a load cell at each end to measure the weight of the pot and guarantees plant stability thanks to its triangular shape. It also has a vertical trellis with adjustable angle to keep the plant upright, ensuring their growth and to allow the study about the influence of trellis angles in crop evapotranspiration.
