Pores and organic matter take a multitude of forms in soil and their characteristics change in space and time following a change in tillage practices as a new "steady state" is approached. Information on the variation with depth (stratification) in the characteristics of pores and organic matter and the rates of change in these characteristics is vital to interpreting the short- and long-term impacts of a reduction of tillage on the productivity and hydrology of agricultural soils.
