TLDR
In this article, the causes of crust formation and its effect on the infiltration rate are discussed on untilled soils, and the presence of a crust is a permanent feature on these soils.Abstract:
Sandy soils of the Sahel area in West Africa, mainly cropped to millet (Pennisetum typhoides) are very sensitive to crust formation Crusts strongly reduce infiltration capacity In this area most fields are gently sloping (1–3%) and hence runoff is a widespread phenomenon; on the average 25% of the rain (mainly in the form of a few large storms during the rainy season) is lost by runoff The causes of crust formation and its effect on the infiltration rate are discussed On untilled soils the presence of a crust is a permanent feature Rainfall characteristics play a key role in crust formation Major rainfall characteristics of the Sahel differ significantly from those of other semi-arid areasread more

Agroforestry Trees Improve Water Infiltrability in Semi-arid Tropical Parklands in Burkina Faso
Zomboudré Georges,Ilstedt Ulrik,Gnankambary Zacharia,Nyberg Gert,Somé Léopold,Guinko Sita,Malmer Anders +6 more
TL;DR: In this paper, the authors investigated the effects of Faidherbia albida (apple-ring acacia) and Vitellaria paradoxa (shea butter tree) trees and additions of inorganic fertilizer, leaves and compost on soil infiltrability in two agroforestry parkland systems in the western part of Burkina Faso.

Soil Crust Development throughout a Two-Dimensional Profile by Discrete Element Method
Seungcheol Yeom,Kurt Sjoblom +1 more
TL;DR: In this paper, a two-dimensional (2D) modeling approach was employed to minimize the computational effort and maximize the number of particles in the soil profile, and the effect of the restitution coefficient between the soil and the rain for the nonlinear elastic constitutive model was evaluated.

An example of cartography of runoff capability in the Sahelian region: Sama Dey, Niger
Michel Esteves,Jean-Louis Rajot +1 more
TL;DR: In this paper, a cartographic approach is presented, which combines a soil surface feature map and a slope map to partition the catchment into homogeneous spatial units based upon their runoff production capability.

Predicting rainfall erosion losses : a guide to conservation planning
W. H. Wischmeier,Dwight D. Smith +1 more
TL;DR: The Universal Soil Loss Equation (USLE) as discussed by the authors is a model designed to predict the average rate of soil erosion for each feasible alternative combination of crop system and management practices in association with a specified soil type, rainfall pattern and topography.

Scanning electron microscope observations on soil crusts and their formation.
TL;DR: In this paper, the authors used scanning electron micrographs (SEM) to study the formation of crusts of loessial soils. But they focused on the final stage of the crust formation, when the coarse particles were washed away, and a thin seal skin, about 0.1 millimeter thick, formed the uppermost layer.
