Estimación de erosión potencial bajo dos sistemas de corte de caña panelera utilizando la ecuación universal de pérdida de suelos

In order to compare soil losses in two cutting systems traditio-nally used in the cultivation of sugar cane for the production of panela, a study was carried out in which measurements were made in the field using a rainfall simulator and runoff plots in a vertisol of the municipality of Quebradanegra, Cun-dinamarca, where both types of cut are presented simulta-neously: the cut-off system, in which everything is harvested at once having a homogeneous maturity in the crop and the thinning cut system, in which have an inhomogeneous ma-turity so that only a percentage of the plants is cut at the same time. To estimate the potential soil losses associated with both cutting systems, the Universal Soil Loss Equation (USLE) was used to obtain a mean C factor associated with the type of cut, using the data determined in the field and the erosivity of simulated rainfall intensities. Finally, the anual potential losses of soil was determined under the two cutting systems, where it was observed that the cut-off system has an annual potential erosion 2.2 times greater than the thin-ning cuy system. On the other hand, when comparing the potential losses of soil with a newly prepared and planted lot, without plant cover, the capacity of the sugarcane cane crop is demonstrated to offer a protection to the soil, presenting a potential erosion 9 times smaller, in the case of the cut-off system, with respect to a soil condition without plant cover.
