Última Development of a method for balancing soil organic matter in organic agriculture for practical application Organic Eprints Hoyer, Dipl.Ing.agr. Uta; Brock, Dipl.geogr. Christopher; Hülsbergen, Prof.Dr. Kurt-Jürgen; Leithold, Prof.Dr. Günter. A cooperative research project was started on balancing of soil organic matter in organic agriculture. Existing balancing methods do often not produce plausible results, especially when applicated to organic farming. Therefore the project aim is to evaluate balancing methods and to characterize soil organic matter reproduction in organic farming on the basis of examination of field trials and practice farms in order to revise and adapt coefficients and algorythms in the balance methods. First tentative results from the project confirm the need for a revision and improvement of balancing methods since they did not reflect the actual organic matter dynamic in selected trials sufficiently. Significant differences in soil organic matter reproduction could be... Tipo: Conference paper, poster, etc. Palavras-chave: Nutrient turnover; Soil. Ano: 2006 URL: http://orgprints.org/7221/1/Poster_OrgCon2006.doc Ergebnisse der Anwendung einer neuen Humusbilanzmethode in Dauerfeldversuchen Organic Eprints Brock, Christopher; Hoyer, Uta; Leithold, Prof.Dr. Günter; Hülsbergen, Prof.Dr. Kurt-Jürgen. Humus balance methods aim at the assessment of humus reproduction in cropping systems as an effect of cropped plant species and management. They do not intend to predict actual humus dynamics, which are strongly dependent on land-use history and environmental site conditions. Therefore, the validation of humus balance methods is a methodical challenge. This paper presents results from the validation of a new method for humus balancing with different approaches. The first validation approach is relating humus balance saldi to humus content development in long-term field experiments. The second approach is relating humus balance saldi differences between field experiment treatments under similar site conditions to differences in humus dynamics...
