2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
Ackerbaufruchtfolge auf anmoorigen Böden (>10% organische Substanz) mit Herausforderungen im Umgang mit Stauwasser aufgrund einer Wasserundurchlässigen Tonschicht im Unterboden.
2.2 Detailed description of the Technology
Description:
Der Landwirt bewirtschaftet in Kallnach verschiedene Felder in Pacht. Die beschriebene Parzelle umfasst ca. 1,9 Hektaren. Sie hat eine Länge von ungefähr 220 Metern und eine Breite von ungefähr 90 Metern. Der Oberboden (A-Horizont) ist unterschiedlich mächtig. Der organisch (>10%) nutzbare Oberboden variiert zwischen ca. 25 und 80 Zentimeter. Die Neigung über die Untersuchungsfläche ist nahezu null Grad. Es ist im Norden der Parzelle eine leicht konkave Struktur zu erkennen. In dieser Senke hat der Landwirt wiederholt mit derart Stauwasser zu kämpfen, dass er beträchtliche Ernteausfälle einbüsst.
Der Landwirt bepflanzt die Parzelle mit einer Zuckerrübe-Kartoffel-Getreide-Bohnen Fruchtfolge. Diese wird teilweise durch eine Gründüngung ergänzt. Sein Anbausystem ist geprägt durch die Drainage zur Entwässerung der Böden. Diese bewirken erst die Nutzung des Landes als Kulturland und sind daher essentiell für das Funktionieren des Systems. Trotzdem können sie die angesprochene Problematik in der Senke nicht vollends lösen.
Für die Bepflanzung der Kulturen verwendet der Landwirt verschiedene Maschinen. Der Boden wird regelmässig mit Pflug und Grubber bearbeitet.
Das zurzeit betriebene System wurde vom Landwirt selbst initiiert.
