Homogeneidad edafica relacionada con la biomasa herbacea. Subcuenca baja del rio Castan.

Arellano R. | Jaimes E.W.
The objective of this assay is to determine the existing relation between the productivity of dry aerial biomass of four experimental plots, selected of random within a grassland with predominace of the Cynodon sp species, and the edaphic homogeneity, applying the procedure proposal by Jaimes located in the low part of the Castan river basin. The sample area was subdivided in four experimental plots: A, B, C and D, with surface of 4,0; 4,5; 3,0 and 3, 5 hectares respectively. In each of these places to the vegetation and soil attributes are described. The plots of ground were sampled in 26 points uniformly distributed, in microplots of 1 m2 each one. Four matrices of data were elaborated of 26 observations each one, with the purpose of calculating the Multivaried Homogeneity Index (MHI), proposal by Jaimes (1988). The obtained results allow to prove that there is a direct and consistant relation between the production of dry aerial biomass of the plots with the edaphic homogeneity associated with the physical and chemical characteristics of the epipedon.
