Einfluss von Kompost und Gärgut auf Pflanzenwachstum und –gesundheit: Potential und Grenzen Organic Eprints
Fuchs, Jacques G.; Mayer, Jochen; Berner, Alfred.
One hundred Swiss composts and digestates were investigated in order to evaluate their influence on plant growth and health. Important differences in biological compost quality and on the impact on soil fertility and on plant health were observed. The most important limiting factor of compost quality is the possible immobilization of mineralized nitrogen by some composts. However, quality composts have a good potential to protect plants against diseases. More attention should be paid to the control of the composting process in order to improve the biological quality of composts with more beneficial effects on crops.

Soil properties, crop yield and quality with farmyard manure with and without biodynamic preparations and with inorganic fertilizers Organic Eprints
Raupp, Joachim; Oltmanns, Meike.
Since 1980 a 2 factor fertilization experiment compares 3 fertilization types (farmyard manure with and without biodynamic preparations vs. inorganic fertilizers) applied at 3 different rates in a 4 field crop rotation. Except for fertilization all other elements of cultivation were the same in all treatments and followed normal organic farming practices. The key results of the experiment obtained in more than 2 decades are reported with respect to soil parameters (e.g. organic carbon content, microbial biomass and activity, particulate organic matter, amino acid content, carbon source utilization, micronutrients), crop parameters (yield formation depending upon fertilization and site conditions, mycorrhiza development) and weed abundance.
