It was hypothesised that, regardless of soil type, the N2O emissions would peak at the previously reported Dp/Do value of 0.006. Four pasture soils, sieved and repacked to three different bulk densities, were held at nine different soil matric potentials between near saturation and field capacity...
This paper deals with predicting flow accumulation, drainage class, and soil and vegetation type within small headwater catchments (<20 ha) of two contrasting forested areas in northern New Brunswick, Canada, based on digital elevation modelling. A digital elevation model (DEM), with a point samp...
The optimal field for agricultural production has minimal slope, variation in soil type, and drainage requirements. Irrigation systems should be properly designed for the inherent topography of the field, soil and crop characteristics, and quantity and quality of the water supply. However, a number ...
Cavan were accurately mapped with respect to soil type, soil slope and topsoil depth. The results show that at least 5 contrasting soil Orders/Great Groups occur in close proximity to one another and that representatives of nearly all conventional units of soil slope and soil drainage classes ...
(A) A conventionally constructed embankment with technical drainage. The forming of the relief, the soil, and the vegetation are not adapted to the environment of the site. (B) A direct-shifted, completely new embankment is shown below the red line; above is the natural terrain. Compare to...
