The Spatial Organization Of Soddy-lithogenic Soils On The Grey-green Clays

Abstract

G. Ð?. Zadorozhna

On geostatistical analysis of soil penetration resistance some the three types of pedons were determined which constitute the spatial organization of the soddy-lithogenic soils on gray-green clay. Clusters A and B are characterized by presence of local maxima of soil penetration resistance in middle soil horizons. For cluster A the local maximum is observed in the horizon of 15-30 cm, and for cluster B – in horizon of 25-30 cm. For cluster C the maximum is reached at the depth of 30-35 cm and it is never changed with the subsequent increase of depth. Pedons of type C occupy the areas with round-amoeboid forms which distanced from each other. Pedons of type B according to their characteristics are transitional forms from A to C. They have fewer areas, but their shape is long and covers larger area than other types of pedons. According to rhe shape the A pedons correspond to the areals of type C, but occupy much larger area.
