Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - At the same time that significant environmental changes are being observed in different regions of the planet, demand for food has grown and exerted strong pressure on water use for irrigation. Irrigated agriculture is the economic activity that demands the greatest amount of water, and due to the decrease in its quality for agricultural use and its availability due to droughts and increased demand for different uses, various technological tools have been used to optimise its use in agricultural production. Among these, automatic irrigation system activation devices stand out, which aim, for example, to prevent excessive water application, and the use of hydrophilic substances, which contribute to increasing the water retention capacity of the soil. This book presents the performance of a low-cost automatic actuator for localised irrigation in the presence of different doses of a water-retaining polymer in the soil for the production of smooth lettuce in a protected environment.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Al mismo tiempo que se observan importantes cambios ambientales en diferentes regiones del planeta, la demanda de alimentos ha crecido y ha ejercido una fuerte presión sobre el uso del agua para el riego. La agricultura de regadío es la actividad económica que más agua consume y, debido a la disminución de su calidad para uso agrícola y de su disponibilidad a causa de las sequías y el aumento de la demanda para diferentes usos, se han utilizado diversas herramientas tecnológicas con el fin de optimizar su uso en la producción agrícola. Entre ellas, destacan los dispositivos automáticos de activación de los sistemas de riego que tienen como objetivo, por ejemplo, evitar el uso excesivo de agua, y el uso de sustancias hidrofílicas, que contribuyen a aumentar la capacidad de retención de agua en el suelo. Este libro presenta el rendimiento de un activador automático de bajo costo para el riego localizado en presencia de diferentes dosis de un polímero hidrorretentor en el suelo con el objetivo de producir lechuga lisa en un ambiente protegido. …
