Description

In the context of new irrigation techniques the Compagnie Nationale d'Amenagement du Bas-Rhone et du Languedoc (B.Rh.L.) has developed a process of localized irrigation by perforated distributors. Conditions were defined for the optimum use of this process, especially the distribution of water in the ground. The study was carried out in a peach orchard in stony ground. The neutronic method was used to measure the soil moisture content. Because of the heterogeneous stone size distribution it was necessary for the specific humidity determination to take into account the dry apparent density. This parameter was measured by gammametry

Abstract (French)

Dans le cadre des nouvelles techniques d'irrigation, la Compagnie Nationale d'Amenagement du Bas-Rhone et du Languedoc (B.Rh.L.) a mis au point un procede d'irrigation localisee par rampes perforees. On a defini les modalites d'utilisation optimale de ce procede et principalement la distribution de l'eau dans le sol. L'etude a ete realisee dans un verger de pechers en sol caillouteux. On a utilise la methode neutronique de mesure de l'humidite des sols. La repartition heterogene de la pierrosite a necessite, pour la determination de l'humidite volumique, la prise en compte de la densite apparente seche. Cette caracteristique a ete mesuree par gammametrie
