Managing soil fertility in organic farming systems
12 Complex relationships exist between different components of the organic farm and 13 the quantity and quality of the end products depend on the functioning of the whole 14 system. As such, it is very difficult to isolate soil fertility from production and 15 environmental aspects of the system. Crop rotation is the central tool that integrates 16 the maintenance and development of soil fertil...
متن کاملSoil fertility and biodiversity in organic farming.
An understanding of agroecosystems is key to determining effective farming systems. Here we report results from a 21-year study of agronomic and ecological performance of biodynamic, bioorganic, and conventional farming systems in Central Europe. We found crop yields to be 20% lower in the organic systems, although input of fertilizer and energy was reduced by 34 to 53% and pesticide input by 9...

متن کاملManaging helminths of ruminants in organic farming.
The use of anthelmintics is strongly limited in organic farming. This may induce a change in the intensity (no of worms) and diversity (proportions of species) of helminth infection. Helminths remain a major preoccupation in organic sheep farming: high levels of infection have been recorded on several farms and helminth diversity is always higher. The helminth infection in milk cattle of northe...
متن کاملSoil suppressiveness and functional diversity of the soil microflora in organic farming systems
Arable fields of 10 organic farms from different locations within the Netherlands were sampled in four subsequent years. The soil samples were analysed for disease suppressiveness against Rhizoctonia solani, Streptomyces scabies and Verticillium dahliae. Furthermore, a variety of microbial characteristics and chemical and physical soil properties were assessed. All these characteristics and dif...
