Ineed understanding this excerpt:
quantitative formulation: a significant gap remains between soil architectural parameters and field-measured soil functions at different scales. pore space is a new arena for pedologic research, as it emphasizes the nature, origin, and significance of pore space in various soil functions. however, how to link pedologic features, pore characteristics, and soil functions at different scales is a challenging and yet critical question to be answered. the link between soil maps and soil functions is also needed, especially quantitatively, but it is largely missing.
i don't understand what it means ' at different scales.' also, how can we link soil maps and soil functions?
