| Sumario: | To make decisions regarding land use in the province of Misiones, it is essential to know their erosion, which is made difficult by the lack of information on the erosivity of rain. The objective of this article is to determine the erosivity factor R and the temporal variability of precipitation from different indices such as Fournier (IF), Modified Fournier (IMF), Precipitation Concentration (ICP) and Total Erosivity (EIT). Records from 14 stations of the National Water Information System of the National Hydrological Network and data from the meteorological station of the National Institute of Agricultural Technology (INTA) Cerro Azul were used, a series of 28 years from 1991 to 2018. As a result of the study, moderate to strong erosivity was obtained and the ETI index presents high erosive potential. The high correlation factor R² = 0.84 allows us to use the erosivity factor R as reliable data when correlating with IET, to define the erosivity of rain and thus generate recommendations for the management and use of soils for the purpose of conservation thereof. |
