Abstract:
Taken from the methods of https://doi.org/10.1016/j.agee.2020.107237:
Vegetation surveys were performed once in July for both study years. Plant species were classified and each species' percent cover for both the arable plant community and the crop were visually estimated per plot. Species were divided into rare arable plants, other spontaneously occurring arable plants, the sown crop species, and volunteer crops that re-emerged after cultivation in previous years. To measure the productivity of our plots, both the crop biomass and arable plant biomass (rare arable plants + volunteer crops + spontaneous arable plants) were collected in July and August in both study years. For the arable plant biomass, three 0.5 m × 0.5 m sampling quadrats were randomly placed in the plot, harvested, and dried at 65 °C for 48 h. Crop biomass was measured after cutting, drying, and weighing three randomly selected crop rows per plot. To minimize edge effects, the outmost crop rows were excluded from the sampling. Arable plants and crop biomasses were projected as g m ⁻².
