I am familiar with the work done by Le Bissonnais, but wondered if there's anything available that departs from a combination of texture and OM content.
Hi Robert, what you mean excatly with "soil susceptibility" => electromagnetic susceptibility of the soil ?
Hi Stephan, thanks for your interest. What I mean is the degree to which a soil surface develops into a superficial crust with a relatively high resistance to infiltration. This crust formation is the result of the detachment and re-arrangement of fine particles at the soil 'skin', usually the result of raindrop impact + overland flow and subsequent drying.
Hello Robert
I have recently finished my thesis on the effect of rock fragment on hydraulic conductivity of stony soils and also adopting the existing PTF to predict Ks in stony soils. Concerning your question I propose you to have look on the works of
Childs, 1969: Childs, E.C, (1969). The Physical Basis of Soil Water Phenomena. Wiley,London, 274 p.
and
Brakensiek et Rawls, 1994: Brakensiek, D.L., W.J. Rawls. (1994). Soil containing rock fragments: effects oninfiltration. Catena. v. 23, pp. 99-110.
The most important parameter which influences the Ks of the soil in the PTFs is the Bulk density (BD) of the soil. I think this parameter can integrate the effect of the crusts. there is a large variety of BD-PTFs which can help you to predict the BD of the soil but I am not sure that you can find one for the crusted soils.
If u are intrested, we can talk more about this subject.
Good luck
