Abstract:
... BACKGROUND AND AIMS: Studies verify that intercropping increases soil macro-aggregates but the mechanism underlying the increase is poorly understood. METHODS: Three long-term field experiments were conducted starting in 2009 at three sites in an oasis in northwest China. The first was a split-plot design: Rhizobium (with or without inoculation) and three cropping systems (faba bean/maize intercro ...

Abstract:
... BACKGROUND AND AIMS: Enhanced crop productivity by intercropping is commonly assumed to be driven by resource complementarity. However, relatively few studies have directly measured resource acquisition to assess potential mechanisms underlying enhanced performance of intercropping. METHODS: A long-term field experiment with three P application rates (0, 40, 80 kg P ha⁻¹ yr.⁻¹) and four maize-base ...

Abstract:
... BACKGROUND AND AIMS: Competition between intercropped species is important for yield advantage, but little attention has been given to interspecific competitive dynamics in intercropping. METHODS: A field experiment with five cropping systems (wheat/maize, barley/maize intercropping, wheat, maize and barley sole cropping), two N levels (0 and 225 kg N ha⁻¹) and two maize mulching treatments (with ...

Abstract:
... AIMS: Intercropping increases aboveground and belowground crop productivity, suggesting potential for carbon sequestration. Here we determined whether intercropping affects decomposition of soil organic matter (SOM) and root litter. METHODS: We measured in the laboratory and the field the breakdown of SOM, root litter of maize, wheat, or faba bean, litter mixtures, and a standard substrate (compos ...

Abstract:
... BACKGROUND: Overyielding (i.e., mixtures of crops yielding higher than expected when compared with monocultures) and increased nutrient acquisition have been found in many intercropping systems. However, there are very few published studies on long-term changes in soil chemical and biological properties in intercropping systems compared to sole cropping. METHODS: A field experiment was established ...

Abstract:
... Increasing crop nitrogen use efficiency while also simultaneously decreasing nitrogen accumulation in the soil would be key steps in controlling nitrogen pollution from agricultural systems. Long-term field experiments were started in 2003 to study the effects of intercropping on crop N use and soil mineral N accumulation in wheat (Triticum aestivum L. cv 2014)/maize (Zea mays L. cv Shendan16), wh ...

Abstract:
... Interspecific interactions and soil nitrogen supply levels affect intercropping productivity. We hypothesized that interspecific competition can be alleviated by increasing N application rate and yield advantage can be obtained in competitive systems. A field experiment was conducted in Wuwei, Gansu province in 2007 and 2008 to study intercropping of faba bean/maize, wheat/maize, barley/maize and ...

Abstract:
... Symbiotic nitrogen fixation is commonly inhibited by N fertilization in intensive farming systems. We hypothesized that intercropping alleviates the inhibitory effect of N fertilization on nodulation and N₂ fixation of legumes. Two years of field experiments (2006-2007) with different N-fertilizer rates (0, 75, 150, 225, 300 kg N ha⁻¹) were carried out to test the hypothesis in a faba bean (Vicia ...

Abstract:
... Wheat (Triticum aestivum L.) production by intercropping with faba bean (Vicia faba L.) has increased in popularity but is often associated with severe wheat powdery mildew (Blumeria graminis (DC.) Speer). Very little is known about the effects of below- and aboveground interspecific interactions on wheat nitrogen (N) nutrition and occurrence of wheat powdery mildew. A greenhouse pot experiment ex ...
