Micromorphology of a Typic Natrustalf

The morphological, physical, chemical and micropedological studies were carried out to investigate the genesis of calcic layer in Typic Natrustalf of Seonsar block in Saraswati range of Kurukshetra forest division, Haryana. The information, thus generated revealed that platy epipedon, dominance of ultramicro-and micro-voids, plugging of meso-and macro-voids at the surface horizon restrict the infiltration of water as evident by the presence of slaking crust. The arrangement, size, shape and frequency of particles and the characteristics of the thin sections of the peds revealed sepic plasmic fabric. The calcic horizon that had soft and disseminated lime developed into hard concretions, nodules through the course of formation of calcite crystals may subsequently lead to formation of calcite layer by displacing the surrounding material.
