TL;DR: In this paper, the effects of maize-legume intercrops on the weed community in an organic cropping system were analyzed and a statistically significant negative correlation between the fraction of photosynthetically active radiation (F int PAR) intercepted by the canopy, and both weed density and weed dry matter was found.
Abstract: In organic agriculture, intercropping is receiving increasing attention as it offers potential advantages for increasing sustainability in crop production. However, intercropping can increase competition between crops and weeds. In this study, we analyzed the effects of maize–legume intercrops on the weed community in an organic cropping system. We were concerned only with competition between crops and weeds for light. We recorded a statistically significant negative correlation between the fraction of photosynthetically active radiation (F int PAR) intercepted by the canopy, and both weed density and weed dry matter. Maize–legume intercropping led to a higher soil canopy cover (leaf area index) than sole crops. The lowest values for F int PAR were received in sole crops. Thus, in maize–legume intercrops the decrease in available light for weeds led to a reduction of weed density and dry matter, compared to sole crops. Intercropping maize and legumes considerably reduced the weed density in the intercrop ...

TL;DR: The design of a rather complex experiment to explore the possibilities for both short-term and long-term increases in organic cereal production through manipulation of crop-rotation design on different soil types is described.
Abstract: A field experiment is being conducted which focuses on crop rotations for cereal production in organic farming. The objective of the experiment is to explore the possibilities for both short-term and long-term increases in organic cereal production through manipulation of crop-rotation design on different soil types. This paper describes the design of a rather complex experiment, and later papers will describe and discuss the results. Three factors are included in the experiment in a factorial design with two replicates: (1) fraction of grass-clover and pulses in the rotation (crop rotation); (2) catch crop (with or without catch crop or bi-cropped clover); and (3) manure (with or without animal manure applied as slurry). All fields in all rotations are represented in each year. The experimental factors are defined to allow management to be adjusted for optimization of the individual treatment combinations. This makes the systems more realistic and the results more applicable in practical farming. The exp...

TL;DR: The results show that manure application is a key factor in maintaining good crop yields in arable organic farming on sandy soils, and in securing crops that are sufficiently competitive against perennial weeds.

TL;DR: In this article, the authors compared identically managed organic and transitional plots, differing only in duration of organic management (>5 versus <1 year). Conventional plots were included for reference purposes.

TL;DR: The main difference is that biodynamic farmers add eight specific amendments, called preparations, to their soils, crops, and composts as mentioned in this paper, which can improve biological soil properties and increase crop root growth.
Abstract: Biodynamic and organic farming are similar in that both are ecologically oriented and do not use chemical fertilizers and pesticides. The main difference is that biodynamic farmers add eight specific amendments, called preparations, to their soils, crops, and composts. Recently, there has been an increasing interest in biodynamic farming practices and systems because they show potential for mitigating some detrimental effects of chemical-dependent conventional agriculture. Only a few studies examining biodynamic methods or comparing biodynamic farming with other farming systems have been published in the refereed scientific literature, especially in English. This paper summarizes data from previous studies, both published and unpublished (theses), that have compared biodynamic and conventional farming systems with respect to soil quality or profitability. These studies have shown that the biodynamic farming systems generally have better soil quality, lower crop yields, and equal or higher net returns per hectare than their conventional counterparts. Two studies that included organic management treatments with and without the preparations showed that the preparations improved biological soil properties and increased crop root growth. However, more research is needed to determine whether the preparations affect soil physical, chemical, and biological properties and crop growth and, if so, their mode of action.
