The ef®ciency of stone lines in checking runoff and in improving soil water storage increased with reduced stone line spacing (runoff was reduced by an average of 5% on plots where
The extent and types of soil surface crusts were shown to depend on multiple factors such as soil properties, land use, terrain type and position, rainfall intensity and
5A clari®es the different backgrounds of the working depth effect: increased covering of garden cress solely occurs in the soil ridges (due to soil level upheaval), whereas
Data from runoff plots operated over a ®ve year period show that signi®cantly less overland ¯ow is generated with a seasonal no-till ridge system than with contour tillage or
However, in the case of clay soil (with 1.3±10.4% organic matter) it appears that organic matter increases the strength of moist soil aggregates, and decreases the tensile strength
Providing that the organic matter carried in soil water has surface proper- ties similar to those of organic matter in the soil matrix, transport on organic matter seems likely
Ploughing and treatment application occurred twice in 1995 at Boghall, before sowing spring barley in April and winter barley in September, and once in August 1996 at North
(1987) found that compaction of wet soil by tractor traf®c increased N loss by denitri®cation 3±4 fold and decreased wheat yield by 25%. The observed restricted growth increased
