- Abstract
Objective. To characterize the vertical forces transmitted to the soil by agricultural machinery used during the mechanical harvesting operation of Saccharum spp. (sugarcane) with self-turning wagons in two soils of the Valle del Cauca, Colombia, through the development of an electronic device for measuring compression forces in the soil. Methods. The components used for the construction of the sensor were: a microcontroller board, an AD620 electric signal amplifier module, an LCD screen, and a compression force transducer with a nominal capacity of 10 Mg. The compression forces transmitted to the soil by the sugarcane harvesting system with self-turning wagons were quantified up to a depth of 50 cm and were related to the phenomenon of compaction through the properties of apparent density in wet conditions and mechanical resistance to penetration. Results. It was found that the rear tire of the tractor transmitted the highest compression forces. At a depth of 15 cm, the values were 120.42 kPa and 108.29 kPa, while at 50 cm, they were 35.52 kPa and 29.46 kPa. The forces transmitted by the machinery increased the values of apparent density in wet conditions and mechanical resistance to penetration above critical values for the development of sugarcane. Conclusion. The intensive traffic of machinery on the soil induces vertical compression forces, which can result in soil compaction.
