Potential compaction in two soils of the flat portion of valle del cauca

Samples from the top 20 cm of two soils in CIAT Palmira (Calciustoll and Haplustoll both vertic mixed loaxny isohipertermic 0.5% slope) used in both secondary forest cover and diverse crops for more than fifty consecutive years were compacted into the apparatus of Richards at two soil moisture conten...

description Samples from the top 20 cm of two soils in CIAT Palmira (Calciustoll and Haplustoll both vertic mixed loaxny isohipertermic 0.5% slope) used in both secondary forest cover and diverse crops for more than fifty consecutive years were compacted into the apparatus of Richards at two soil moisture contents (O. 1 and 0.5 bar) to compare the point of maximum soil compaction and its influence in the soil bulk density changes, rate of oxygen diffusion, aeration porosity, saturated hydraulic conductivity and rupture modulus. A complete randomized design with factorial arrangement was used which consisted of 2 soils x 2uses x 2 soil moisture content x 3 repetitions and means separated by Duncan probe. The study showed that high soil content of O.M. do not always prevent soil degradation due to of agricultural machinery traflic at high soil moisture contents. Irrespective of soil use, siltier Calciustoll had a slightly more potential to compaction than Haplustol, and continued cultivation of the two soils has made them more susceptible to physical daxnage, because in wet condition compacted to the extreme and showing physical degradation which in practice may result from traflic on soils, and in moist state, compacted moderately.

Se utilizó un diseño completamente al azar con arreglo factorial (dos suelos, por dos usos, por dos humedades) con tres repeticiones. Para la separación de medias se utilizó la prueba de Duncan (P and lt; 0.05). El  estudio concluye que los altos contenidos de M.O. no siempre evitan la degradación del suelo por e6ecto del  trãfico de maquinaria en contenidos de 9umedad altos= independientemente del uso, el Calciustol más limoso tuvo ligeramente mayor potencial a la compactación que el Haplustol; y el cultivo continuado de los dos suelos los ha hecho más susceptibles al daño físico, ya que en esta- do  muy húmedo, se compactaron al extremo y mostraron el deterioro físico que en la práctica puede acarrear el trãfico de maquinaria so and gt;re el suelo% y en estado 9ümedo se compactaron moderadamente.application/mswordspaUniversidad Nacional de Colombia Sede Palmirahttp://revistas.unal.edu.co/index.php/acta_agronomica/article/view/32456Universidad Nacional de Colombia Revistas electrónicas UN Acta AgronómicaActa AgronómicaMadero Morales, Edgar and Peña Artunduaga, María Elvira and Escobar, Betsy Yadira and Fernando García, Luís (2012) Potential compaction in two soils of the flat portion of valle del cauca.
