Abstract: An investigation was made of the time taken by a ley to change the physical state of an old arable soil ro that of an old grassland soil so that, for example, its physical condition on ploughing is the same as that of old grassland on ploughing. The process was found to be slow, taking possibly 50 years or more on some clay soils. On coarse sandy soils the process may be considerably faster, e.g. 5-10 years. I Old pasture and old grassland have been used synonymously.

“…The index derived from contrasting long-term sod and no sod in rotation (SDI SOD ) had the strongest level of agreement with farmer SQ ratings of the three indices. This is not surprising as the positive impact of sod on SQ has been described by many authors 47 49 .…”

“…The index derived from contrasting long-term sod and no sod in rotation (SDI SOD ) had the strongest level of agreement with farmer SQ ratings of the three indices. This is not surprising as the positive impact of sod on SQ has been described by many authors [47][48][49] . The index based on farmer ratings (SDI FR ) was calculated as a linear function of two parameters, C NMW and C SIR , which were selected because they optimized discrimination between unpaired good and poor rated soils.…”

“…There is an increase in waterstable soil aggregates but the rate ofchange is slow (Low 1955). On medium or heavy textured soils many years must lapse before the physical condition of the soil reaches that found under permanent pastures.…”

“…Adverse structural conditions such as compaction in or beneath the plough layer, and surface crusting, cause restrictions in crop growth which depress yields (Batey and Davies, 1971;Low, 1973). When intensive arable farming replaces systems which include long grass leys, a progressive decline in organic matter levels is frequently noted.…”

“…A M O N G the soil constituents which are known to influence soil physical conditions the role of organic matter has been much emphasised (Low, 1955;Russell, 197 1). It has been found to influence soil compactibility (Soane et al, 1972), soil bulk density and porosity (Davies, 1975), plastic limits (Baver, 1930;Boekel, 1965) and aggregation (Greacen, 1958).…”
