  • Die Eigenschaften und die Funktion des organisch-zeolithischen Biodüngers
    Peter J. Leggo
    Dieses Buch behandelt eine neue biologische Methode der Pflanzenernährung. Im Gegensatz zu herkömmlichen chemischen Düngemitteln gehen Nitrat, Phosphat und Kalium zusammen mit nützlichen Spurenelementen nicht durch Diffusion durch den Boden nach Regenfällen verloren. Aufgrund der langsamen Freisetzung nimmt eine wachsende Pflanze die Nährstoffe in einer Geschwindigkeit auf, die...

  • Les clés de l’identification des minéraux
    Riadh Abidi
    Les minéraux ne présentent que rarement les belles formes cristallines aux faces brillantes, aux arêtes rectilignes et aux sommets acérés. Ce sont le plus souvent des grains informes, des masses mamelonnées, feuilletées, des encroûtements. On réserve donc l’appellation de cristal à ceux qui montrent une forme cristalline sur laquelle on distingue des faces, des arêtes et des so...

  • Journal of a Tour through North Wales and Part of Shropshire with Observations in Mineralogy and Other Branches of Natural History
    Arthur Aikin
    Journal of a Tour through North Wales was Aikin’s first book, published in 1797, when he was only 24 years old. It is based on a tour undertaken two years earlier, inspired by Horace Bénédict de Saussure’s Voyages dans les Alpes. Like other contemporaries who visited the region, he stopped at well-known destinations-Bala, Llanrwst, Beddgelert, Dolgellau, Anglesey, Llandudno, Ab...
