Última Understanding soil nitrogen supply: organic matter quality and quantity Organic Eprints Shepherd, Mark; Hatch, David; Hatley, Damian. The soil organic matter (SOM) contents of organic and conventionally farmed soils were compared. Whilst the quantity of SOM was found to be similar with both systems, the quality of SOM differed in respect of higher amounts of N released by the organic soils under anaerobic incubation. This indicated a greater potential rate of mineralization and suggested that the inherent fertility of the organic soils had been improved Tipo: Conference paper, poster, etc. Palavras-chave: Nutrient turnover; Farming Systems; Soil quality.

This report was presented at the UK Organic Research 2002 Conference. Soil structure was assessed in over 90 fields (organic and conventionally farmed) covering mixed, stockless and pasture farming systems. A combination of spade and an objective scoring system based on the degree of aggregation and porosity was able to detect differences between fields. On average, in the fields sampled, topsoil structure was slightly better on the organic farms though, even on the conventional fields, structure was unlikely to limit crop growth.
