Compactación del suelo y nogal pecanero (Carya illinoensis Koch)

Abstract

Soil Compaction in the orchard pecan (Carya illinoensis Koch. The objective of this assay was to evaluate the soil compaction or the resistance to the penetration, in a pecan orchard with a constant soil management for 40 years. The description of the morphology feature was made in three holes to identify the compact layers and their behavior in the subsoil. Besides the numerical measurement of this layers with the static penetrometer and their relation with the apparent density, and the water infiltration in the soil, and the origin of and effect on the tree’s roots was performed. Generally speaking, two compact layers were delimited at different depths that cause dissimilar surroundings in detriment of radical development and of the soil’s microbial flore.
