Die vorliegende Arbeít febasst sich mit der Bestimmung der Beziehungen zwischen der Textur auf der einen Seite und dem Wassergehalt bei pF von 4.2 bis 6,0 (Tates Wasser) auf der anderen Seite, der Böden van West Andalusien. Die Regressionanalyse der Ergebnissen zeigen einen starken Zusammenhang zwischen dem Wassergehalt und der feinsten...

Se trata de un sistema de captación del agua que se escaparía por escorrentía tras un episodio de lluvia mediante unas minipresas o diques prefabricados que se clavan en el suelo perpendiculares al flujo en los canales de desagüe naturales.Estas minipresas permiten frenar parcialmente este flujo, captarlo y conducirlo mediante unas tuberías...

La variación del diámetro del tronco es un sistema que se está sugiriendo para la programación del riego de varias especies frutales pero que no tiene resultados claros en olivo. El parámetro de estos ciclos más tradicionalmente empleado es la máxima contracción diaria (MCD). En este trabajo se pretende analizar los posibles causantes que...

En este vídeo se explica una técnica agronómica de programación de riego deficitario en base a medidas de estado hídrico en planta. El indicador que se usa es la variación del diámetro del tronco. Esta medida, basada en dendrometría, permite la monitorización continua y a distancia del cultivo. Permitiendo un ajuste del riego diario, basado en...

The scarcity of water for agricultural use is producing a generalization of deficit irrigations in most of the fruit trees. Regulated deficit irrigation in olive trees is scheduled with a period of water stress during the pit hardening phase with low or, even, no decrease in yield. During this phenological stage, fruit is a great sink of...

Maximum daily trunk shrinkage is a common measurement in irrigation scheduling of fruit trees. But the strong relationship between these measurements and the environment severely limit field applications. Reference baselines are the solution for understanding the influence of environmental conditions. Nevertheless, the extrapolation out of the...

Maximum daily shrinkage (MDS) is the parameter of daily cycle of trunk diameter most widely suggested in irrigation scheduling for several fruit trees. However, as in other plant-measured approaches, the irrigation decision may be difficult due to the influence of the environment on the values obtained. Reference equations of MDS have been...

Regulated deficit irrigation (RDI) results are affected by the actual water stress level reached during the treatments. The irrigation scheduling based on water status measurements, such as trunk diameter fluctuations, can control in an accurate way the water restrictions. However, the number of works that use these indicators as isolate...

Regulated deficit irrigation (RDI) is an irrigation strategy designed to save water with a minimum impact on yield and fruit quality (Chalmers, 1989). In stone fruits trees two critical periods have been defined. The first one corresponds to the second rapid fruit growth period (stage III), when water stress induces a reduction in yield due to...

La agricultura de riego es actualmente el mayor consumidor de agua en el mundo (Fereres y Evans 2006)). En muchas zonas áridas y semiáridas la escasez de recursos hídricos junto con la creciente demanda de agua para otros usos están imponiendo una fuerte presión para limitar su disponibilidad en la agricultura, un ejemplo muy claro es el caso...

Measurements obtained by the continuous monitoring of trunk diameter fluctuations were compared with discrete measurements of midday stem water potential (PSIstem) and midday leaf conductance (gl) in adult pomegranate trees (Punica granatum (L.) cv. Mollar de Elche). Control plants (T0) were irrigated daily above their crop water requirements...
