Rice Cropping Systems

Abstract Fallow weeds are more and more common in Chinese rice cropping systems, but are always excluded in studies of vegetative carbon (C) sinks. This study aimed to evaluate the C fixation potential of fallow weeds in rice cropping systems. A six-region, two-year on-farm investigation and a three-year tillage experiment were conducted to estimate C fixation in fallow weeds in rice cropping systems. The on-farm investigation showed that the average mean C fixation in fallow weeds across six regions and two years reached 112 g m–2. The tillage experiment indicated that no-tillage practices increased C fixation in fallow weeds by 80% on average as compared with conventional tillage. The results of this study not only contribute to an understanding of C fixation potential of fallow weeds in rice cropping systems, but also provide a reference for including fallow weeds in the estimation of vegetative C sink. Further investigations are required to determine the effect of C input from fallow weeds on C balance of rice paddies in order to comprehensively evaluate the role of fallow weeds in C cycling in rice cropping systems.

Abstract Weeds occurred during the fallow season can well perform the function of carbon (C) storage due to receiving little human disturbance. This study aimed to evaluate the C storage potential of fallow weeds in rice cropping systems. A six-region, two-year on-farm investigation and a three-year tillage experiment were conducted to estimate C storage in fallow weeds in rice cropping systems. The on-farm investigation showed that the average mean C storage in fallow weeds across six regions and two years reached 112 g m–2. The tillage experiment indicated that no-tillage practices increased C storage in fallow weeds by 80% on average as compared with conventional tillage. The results of this study not only contribute to an understanding of C storage potential of fallow weeds in rice cropping systems, but also provide a reference for including fallow weeds in the estimation of vegetative C sink. Further investigations are required to determine the effect of C input from fallow weeds on C balance of rice paddies in order to comprehensively evaluate the role of fallow weeds in C cycling in rice cropping systems.

The effects of earthworm inoculation and cropping systems on upland rice systems were examined over a four-year period in the Highlands of Madagascar. Each year, endogeic earthworms Pontoscolex corethrurus (Rhinodrilidae) were inoculated (EW+) at a density of 75 ind m−2 or were not inoculated (EW0). Inoculation was tested in three cropping systems: conservation agriculture (CA) and traditional tillage with or without residues restitution. Soil and plant properties were measured during the first three years while soil biological properties were assessed at the fourth year. At the end of the experiment, earthworm density was three-fold higher in EW+ than in EW0, demonstrating the success of the inoculation. Earthworm density was more important in CA than in tillage systems. Earthworm inoculation had higher significant effects on soil and plant properties than cropping systems. Earthworm inoculation had positive effects on soil macroaggregation (+43%), aboveground biomass (+27%), rice grain yield (+45%), and N grain amount (+43%). Intensifying earthworm activity in field conditions to meet the challenge of ecological transition is supported by our study.
