Summary
Description |
Deutsch: Kartoffelfeld, Kanton Bern, Schweiz
Kartoffeln sind besonders anfällig für Erosion. Die Bodenbearbeitung ist sehr intensiv, i.d.R. Pflug und feines Saatbett, die Dämme und Furchen bilden Leitlinien für Oberflächenabfluss, der bei dem welligen Relief in den Tiefenlinien zu Dammdurchbrüchen führt. Kartoffeln bedecken den Boden lange Zeit unzureichend (sowohl nach dem Pflanzen als auch nach dem Abspritzen vor der Ernte). Bei der Ernte wird der Boden stark durchgerührt und die Bodenstruktur zerstört. Möglichkeiten für Boden schonende Anbauverfahren sind beschränkt und kaum verbreitet. English: Potato field, canton of Bern, Switzerland
