Synthetic Polymers as Soil Conditioners : Thirty-Five Years of ExperimentationsIn Philadelphia, on 29 December 1951, at the symposium organized by the American Association for the Advancement of Science on the “Improvement of Soil Structure”, the idea was launched that small amounts (± 1 %) of organochemical polymers could change dramatically soil physical properties.

The “Buried Stones Pocket” : a New Irrigation Technique for Tree Plantations in Arid Regionsor most of the plantations (fig tree, olive tree, apple tree, vine, peach tree) is the rainwater. During dry years these plantations know an important decrease of soil water reserves. This has had consequences on the growth and productivity of the trees, since the trees sometimes die because of water deficiency.
