“…Conversely, the T 10 (Bd = 1.17) and T 20 (Bd = 1.22) treatments exposed the cane to water limitations due to the high θ PR . Though low, these values for critical bulk density are similar to those observed by Tormena et al (1998) and Lima et al (2012) working with clay Oxisols.…”

“…O índice de QFS, desenvolvido por Letey (1985) e caracterizado por Silva et al (1994) como sendo o intervalo hídrico ótimo (IHO), tem apresentado bons resultados (Silva et al, 1994;Beutler et al, 2007;Lima et al, 2012), porém sua aplicação prática fica limitada a períodos em que o solo se encontra com níveis adequados de umidade para que a resistência do solo à penetração possa ser medida.…”

“…As several studies showed differences between the PWP obtained by the physiological method and the estimation in the Richards chamber at 1500 kPa (Cirino & Guerra, 1994;Souza et al, 2002;Klein et al, 2006), the thermocouple psychrometer (WP4) has recently been more widely used to estimate PWP, for the possibility of obtaining soil moisture at 1500 kPa (Costa et al, 2008;Kaiser et al, 2009;Klein et al, 2006Klein et al, , 2010Lima et al, 2012). Descriptions of the process are given by Decagon Devices (2000) and Scanlon (2002).…”
