VARGAS DIAZ, Ruy Edeymar et al. Quantification of soil loss due to runoff under two tillage methodologies in the production of sugarcane for the production of panela. Siembra [online]. 2023, vol.10, n.2, 5435. ISSN 2477-8850.  https://doi.org/10.29166/siembra.v10i2.5435.

Soil degradation has as a direct consequence the loss of biodiversity, the emission of greenhouse gases and the imbalance of the hydrological water cycle, reducing the productive capacity of the soil and its response to amendments and conservation activities, generating low yields and greater water and nutritional requirements. Since these effects are already defined, it is necessary to know the amount of soil that can be lost in order to size the problem. The objective of the study was to quantify the erosion process in a soil under typical precipitation conditions in the Hoya del Río Suárez (Colombia) for the cultivation of sugar cane. For this purpose, an experiment was carried out evaluating two tillage systems (reduced and conventional) in closed runoff plots, where the amount of soil and water washed away in the rainfall events present in a sugarcane crop cycle for panela production was measured. Statistically significant differences (p < 0.05) were observed when the soil was prepared using the proposed system, reducing soil loss by 2.5 times due to runoff compared to traditional tillage, showing to mitigate soil deterioration.
