Summary
This dataset consists of the relative frequencies of all plant species ('weeds') recorded on Section 8 of the Broadbalk Wheat Experiment, 1991-2021. Section 8 has not received any herbicides in its history.
Methods
The assessment method records the presence of individual weed species in 25 random quadrats (0.1m2) per plot. Each year all 18 plots were surveyed meaning 450 quadrats are assessed per year, usually in June. Frequencies refer to the total number of quadrats in which the species is recorded, the maximum being 25 per plot and 450 across all plots in the section.
