Die Bedeutung der Umsetzung von Weizenstroh im Hinblick auf den C‐ und N‐Haushalt von Löß‐Ackerböden

Abstract: Zusammenfassung -SummaryW%luend der Vegetationszeit des Winter-Weizens 1984/85 wurde ein Mikropanellen-Versuch (ObeflLhe I -2 m; Versuchsboden: WB-Braunerde-Pseudogley) mit Hil[e des stabilen Isotops 15N auf einem Schlag der Calenberger WBbiirde bei Hannover durchgefllhrt. Die Uniersuchungen dicnten einerxits der Quaniifizierung der an die Suoheinarbeitung (g 8 tfha) gekoppelten Immobilisation und Remobilisation des boden-und dUngerbUrtigen Stickstoffs, andererseits der Erfassung des Abhaus sowie der Cund N-Me… Show more

“…By contrast, soil amended with wheat straw led to a net immobilization of 2 mg N kg soil −1 . Similar results have been described by Mundra et al [41], Nieder and Richter [42], and Mary et al [39], who state that net immobilization takes place over a short-term period when organic material with a C/N ratio greater than 25:1 is incorporated into soil.…”

“…This specific result in part contradicts observations by Marsh et al [5], who stated that nitrification after urea application is induced quickly under a wide range of conditions, as urea acts as both a C and N source for ammonium-oxidizing bacteria. Concerning total mineral-N, the addition of wheat straw led to lower mineral N concentrations, which may be explained through an increase in the microbial-N fraction [39] during the decomposition of organic material [42].…”
