Cycles of Soils: Carbon, Nitrogen, Phosphorus, Sulfur, MicronutrientsDas Verständnis der Kreisläufe der sogenannten Primärelemente der Natur - Kohlenstoff, Stickstoff, Phosphor und Schwefel - ist die Voraussetzung des korrekten Erfassens jedes Boden-Ökosystems. Die überarbeitete Neuauflage des eingeführten Lehrbuchs bringt dem Studenten neue Entwicklungsrichtungen der Bodenkunde nahe. Zusätzlich aufgenommen wurde ein Kapitel zur anorganischen Bodenchemie. |
