| contents | Physical and mechanical properties of three tropical forest soils on limestone in Chiapas, Mexico Adolfo Campos Biología liquid limit Tropical soil plastic limit shrinkage limit soil water retention The granulometric composition of three soils in a topographical transect was studied, along with soil water retention and characteristics of consistency (shrinkage, plastic and liquid limits). The results indicate that Typic Paleudult soil, found on the lower topographical level and growing coffee (coffea arabica) and corn (Zea mays) crops and forest trees, has the highest percentages of clay (from 56.0 to 93.7%). In contrast, Acrudoxic Kandiudult and Ombroaquic Kandihumult soils which are on the upper topographical level, sustain two types of vegetation: one forest vegetation associated with oak and the other exclusively pine, respectively. These two soils have the lowest percentages of clay (from 42 to 70% and 30.5 to 66.5%, respectively). Water retention at field capacity (0.03 MPa) and permanent wilting point (1.5 MPa) is linked to clay and organic matter contents. Typic Paleudult soil retains the most moisture. On the basic of shrinkage, plastic and liquid limits, we found that the soils preserve their friable state within a wide range of soil water content and the soil highest in clay has an even greater range. Following the plasticity and activity indexes, the soils are slightly to moderately plastic and are composed of low activity clay. The results suggest that the soils present three evolutions on two topographical segments. Each evolution is associated with one type of vegetation. 2002 artículo científico 1405-7247 https://www.redalyc.org/articulo.oa?id=49740201 en http://www.redalyc.org/revista.oa?id=497 Foresta Veracruzana application/pdf Recursos Genéticos Forestales Foresta Veracruzana (México) Num.2 Vol.4 |
