ON THE GRANULOMETRIC ANALYSIS OF LOAMY SOILS: LASER AND CLASSICAL METHODS
Theoretical foundations of soil grain-size determination are considered. Sample preparation methods are provided for disperse cohesive soils according to aggregate, micro-aggregate and dispersive schedules. The results of classical (aerometric and soil pipette) and laser methods of soil composition determination are compared on the basis of comprehensive analysis. Actualization of the federal regulation "Soils. Methods of laboratory granulometric (grain-size) and microaggregate distribution" with the addition of "Sample preparation" and "Granulometric composition determination by laser methods" sections is proposed
