“…The EI 30 index has been most widely used (HOYOS et al, 2005) with good correlation with soil loss in several studies (BERTOL et al, 2007;BERTOL et al, 2008CARVALHO et al, 2009). However, to obtain this factor a series of more than 20 years of rainfall records is recommended, which is not available for many regions of the world (HOYOS et al, 2005;CAPOLONGO et al, 2008).…”

“…From identification of the advanced pattern as predominant in the state of Rio de Janeiro, it can be inferred that soil losses are smaller than they would be if there were predominance of rainfall events with intermediate and delayed patterns (Bertol et al, 2007). The higher water content in the soil preceding the rainfall events, common in these patterns, favors disaggregation of the particles due to the impacts of the raindrops, increases surface sealing, reduces infiltration capacity, and causes greater runoff (Peñalva- Bazzano et al, 2010).…”

“…The indices EI 30 and KE >25 have been widely used to calculate erosivity (Oliveira et al, 2013) since they have provided good correlation with soil losses in different regions (Bertol et al, 2007;Bertol et al, 2008;Silva et al, 2009). These indices are calculated through the product of kinetic energy and intensity of the rainfall (Marques et al, 1997).…”

“…Esses valores foram considerados baixos para esse tipo de solo em razão de o cultivo ter sido conduzido sob sistema de semeadura direta e, também, por tratar-se de solo relativamente resistente à erosão com erodibilidade de 0,011 t ha h ha -1 MJ -1 mm -1 , segundo Bertol et al (2007b). As perdas tenderam, em geral, a diminuir das chuvas do teste 1 para as do 4, em virtude do aumento da proteção do solo pela cultura, que se desenvolveu ao longo do tempo em que as chuvas foram aplicadas.…”
