Soils differ in their resistance to the destructive forces of falling raindrops. The detachment of soil particles from the soil mass is associated with the chemical and physical properties of the soil. These soil properties are not well defined for Nebraska soils. The knowledge of the characteristics influencing detachment of particles will be valuable in improving land use recommendations, soil and water management practices, and soil erosion structures. Moreover, information on detachability of soil particles should permit the development of an equation for predicting soil erosion.

Objectives of the following investigation are: (1) to obtain a functional laboratory rainfall simulator for studying the detachment of soil particles and (2) to use the rainfall simulator and to obtain quantitative data on the detachment of soil separates, fractions of non-treated and Krilium-treated aggregates, and a soil with a long history of management practices.
