- Abstract
Objective. Characterize the compaction induced during the harvest Saccharum spp. with self-turning wagons, in terms of mechanical resistance to penetration and wet bulk density considering their spatial variability. Material and methods. In two sugarcane cultivation lots, located in the department of Valle del Cauca, Colombia, changes in the physical variables of the soil caused by different intensities of machinery traffic during the mechanized harvest were monitored; the variables of interest were subjected to statistical and geostatistical analysis. Results. The initial wet bulk density influenced the compaction of the soils subject to study, while, when its magnitude was greater (1.67 Mg/m3), the susceptibility to compaction was lower, Ending a mechanical resistance to maximum average penetration of 1.83 MPa; compared to what happened when its magnitude was lower (1.56 Mg/m3), compaction was greater, Ending a maximum mechanical resistance to penetration of 2.46 MPa. Conclusion. Traffic intensities equal to or greater than 612.12 Mg.km/ha favored compaction at surface levels (<30 cm deep), bringing the values of soil density and mechanical resistance to penetration to critical values. The horizontal propagation of compaction increased (18.77 m) with lower wet bulk density values (1.56 m3) and reversed in the opposite case (4.55 m with 1.67 M-m3). A mathematical model was provided that explained 50% of the variability of the induced compaction phenomenon with 95% confidence.
