“…On the other hand, the increase in the BD tends to increase the Sq in both grazing intensities and all soil layers evaluated (Figure 1). These results reinforce the common report in the literature that the effects of animal trampling on soil structure have been restricted to the most superficial soil layer (Drewry et al 2008;Carvalho et al 2010;Bell et al 2011;Andreolla et al 2014;Auler et al 2014;Silva et al 2014;Veiga et al 2014). However, it is important to emphasize that Sq showed higher sensitivity in detecting structural differences in the soil in relation to BD, considering the greater depth of the first identified soil layer (Table 1) against the sampled layer for the determination of BD (0 -10 cm).…”

“…A alta intensidade de pastejo pode conferir maior produção animal por área, mas pode prejudicar a produção agrícola, em razão da maior compactação superficial do solo e menor cobertura por resíduos (Veiga et al, 2014). Quando a intensidade de pastejo é muito baixa, há redução na utilização e conversão da forragem, pois há diminuição dos teores de proteína bruta e digestibilidade, o que acarreta menor produção animal, tanto por área quanto por indivíduo (Balbinot Junior et al, 2009).…”

“…O NDVI aumenta proporcionalmente ao incremento da intensidade do verde e da cobertura vegetal. Assim, o menor NDVI aos 15 DAE na maior pressão de pastejo indica menor crescimento inicial da soja nesta circunstância, o que pode ser atribuído à compactação superficial do solo pelo pisoteio animal mais intenso (FRANCHINI et al, 2014;VEIGA et al, 2014) e a menor quantidade de palha na superfície do solo.…”
