“…For these and other reasons, it might not be possible to choose a single 'best' survey method or technique for all fields within an intended target area. A better choice, in purely practical terms, may be to proceed with large-scale survey using a single technique and an 'all-purpose' set of equipment and operational routines, except where there are specific local conditions that suggest a more efficient alternative such as large-scale, highly mechanized and inevitably expensive arrangements like those that have been used so successfully in the very different context of the open pastureland of the Salisbury Plain in southern England (Gaffney et al, 2012(Gaffney et al, , 2018(Gaffney et al, , 2020McOmish et al, 2002 (Ferraby & Millett, 2020) and on the Salisbury Plain in Southern England (Gaffney et al, 2012(Gaffney et al, , 2018(Gaffney et al, , 2020. Relatively few institutes or collaborative teams, however, will have the financial resources to develop or acquire such instruments, and they may well prove impractical in a heavily farmed 'multi-crop' agricultural landscape like that of the lowland between Grosseto and Roselle.…”
