TL;DR: Results from a 21-year study of agronomic and ecological performance of biodynamic, bioorganic, and conventional farming systems in Central Europe found crop yields to be 20% lower in the organic systems, although input of fertilizer and energy was reduced.

TL;DR: The findings show that some AMF species present in natural ecosystems are maintained under organic farming but severely depressed under conventional Farming, indicating a potentially severe loss of ecosystem function under conventional farming.

TL;DR: In this article, the results of a study on the quality of wheat (Triticum aestivum L.) grown in a 21-year agrosystem comparison between organic and conventional farming in central Europe are reported.

TL;DR: In this paper, a long-term field trial comparing a non-fertilised control (NON), two conventionally cultivated treatments (MIN, CON), and two organically-cultivated treatments (ORG, DYN).

TL;DR: In this paper, it was shown that on a long-term organically managed soil (ORG) characterized by higher soil microbial activity, a greater portion of N applied as cattle manure is mineralized and taken up by plants than on a conventionally managed soil that had received exclusively mineral fertilizers (MIN).
