Abstract

A comparative study of the underground phytomass (roots) valúes obtained along four transverse sections of four water courses was made in some semiarid grasslands, that are representative of the CentralWestern área of Spain (Provinces of Avila and Salamanca). In order to perform this study, the following item's were studied: a) the total phytomass valúes for each profile (30 cm depth, 9 cm diameter), b) the horizons or 5 cm horizontal transect, in each section, c) the samples in each profile. Very similar sequences were observed in all the transects, highlighting the effect of relief on underground phytomass, wich is considered a synthesis and an expression of the edaphicclimatic and anthropozoogenic action that governs its development.
