MICROMORPHOLOGICAL ANALYSIS OF A TERRA ROSSA SOIL UNDER OLIVE CROP; PEDOGENESIS AND PEDOTURBATION

Abstract

Permanent tree crops can deeply modify the soil features produced by the pedogenesis processes. Clear microstructural differences were observed in two soil profiles sampled in an olive grove near Sassari (Sardinia, Italy), one under the canopy and one between the tree rows, related either to the farming practices or to the biological activity in the rhizosphere soil
