n the present study, Time Domain Reflectometry TDR and tensiometers were used to follow changes in soil water content and soil water pressure head over time in soil containers filled with a clay loam soil and an organic soil. The moisture content cha

Soil cover and rainfall intensity ( RI ) are recognized to have severe impacts on soil erosion and an interaction exists between them. This study investigates the effect of rainfall intensity ( RI ) and soil surface cover on losses of sediment and th

Field rainfall simulations with intensities of 85 and 170 mm/h were conducted in 2002 and 2005 on a 15-m long slope on a loess soil in Luoyang, Henan Province, P. R. China to study the effects of different soil management practices on the redistribut

Field experiments were carried out to study the effects of different soil management practices on the water balance, precipitation use efficiency (PUE), and crop yield (i.e. winter wheat and peanut) on a loess soil near Luoyang (east edge of the Chin

In order to evaluate the different water flow processes in a silt loam soil susceptible to erosion (slope 16 per cent), a hydrological study was started in 1987 on a standard bare erosion plot under conventional tillage. Tensiometer sets were used to

In the semi-humid to arid loess plateau areas of North China, water is the limiting factor for rain-fed crop yields. Conservation tillage has been proposed to improve soil and water conservation in these areas. From 1999 to 2005, we conducted a field

The macroporosity, and to a lesser extent the microporosity, of swelling and shrinking soils is affected by their shrinkage behaviour. The magnitude of the changes in bulk volume in response to changes in water content is usually described by the soi

Rainfall simulations were conducted on a loess derived silt loam soil (Henan province, P.R. China) under conventional tillage. This tillage practice is widespread and involves the turning of the plough layer and the wheat stubble in July (primary til

A crucial parameter in predicting wind erosion is the deflation threshold shear velocity, which is highly dependent on near-surface soil water. The empirical and theoretical models to predict the deflation threshold as affected by near-surface water
