Der in landwirtschaftlichen Betrieben über Bilanzierungsmethoden feststellbare Stickstoff-Überschuss stellt unbestritten einen Schlüsselindikator für die Bewertung der N-Effizienz sowie der bewirtschaftungsbedingten Umweltbelastung dar. Die versc

The impact of urea prills (1–2 mm) versus urea supergranules (USGs, ∼10 mm), placed at different depths, on the growth and nitrogen (N) use efficiency of spring wheat was investigated under greenhouse conditions. The amount of fertilizer 15N deri

Globally identifying mitigation options for the emission of reactive N gases from agricultural soils is a research priority. We investigated the effect of urea size and placement depth on sources and emissions ofN gases from a Cambisol cropped to spr

The superiority of mixing and deep placement of prilled urea (PU) or urea supergranules (USG) over surface‐broadcast application for reducing nitrogen (N) loss from lowland rice is well established. In upland agricultural systems, rainfall and/or t

SUMMARYFollowing the surface application of granulated urea to grassland, high ammonia (NH3) losses of up to 30% have been reported. The addition of a urease inhibitor (UI) to urea granules could be a way to abate these losses. Field experiments were

As a consequence of the BSE crisis, alternatives for fertilizers derived from animal residues are being sought for use in organic horticulture. Grain legumes (milled seeds of pea, yellow lupine, and faba bean) and organic fertilizers of industrially

Knowledge on short-term and long-term availability of nitrogen (N) after application of organic fertilizers (e.g., farmyard manure, slurry, sewage sludge, composts) provides an important basis to optimize fertilizer use with benefits for the farmer a
