“…In our study, the soil had no exchangeable Al and had elevated levels of exchangeable Ca in the subsoil (0.0 -0.6 m), making it unlikely that a yield increase in response to gypsum application was caused by amelioration of subsoil acidity. No response of soybean yield to gypsum (Quaggio et al, 1993;Oliveira and Pavan, 1996;Caires et al, 2003Caires et al, , 2006 has been attributed to the lower Al toxicity to the root growth in NT systems during cropping seasons that have adequate and well-distributed rainfall (Caires et al, 2001(Caires et al, , 2008. This reasoning does not apply in this study because the soil did not present chemical limitations for root growth (Table 1).…”

“…Na safra de 2010, a precipitação pluvial foi 62 % menor que a média histórica na região (Figura 1), nos três primeiros meses de cultivo (julho a setembro), o que pode ter agravado o efeito tóxico do Al 3+ . Em área de PD de longa duração, Caires et al (2008) notaram que a toxidez do Al 3+ em trigo foi intensificada pelo déficit hídrico durante o desenvolvimento vegetativo da cultura, havendo redução do enraizamento.…”

“…There are considerable root data related to cereal crops (Bolinder et al 1997;Niu et al 2004;Caires et al 2008;Jordan-Meille and Pellerin 2008), especially some of the studies conducted in the 1970s and 1980s (Wellbank et al 1974;Campbell et al 1977;Gregory et al 1978;Buyanovsky and Wagner 1986). However, very limited literature exists in which extensive measurements of roots have been taken for oilseed and pulse crops under field conditions.…”

“…However, crop roots are very difficult to measure, and thus research on roots has lagged behind that on above-ground (AG) biomass. In the literature, there are many studies documenting root characteristics of field crops, but the vast majority of these studies have considered cereals (Campbell et al 1977;Bolinder et al 1997;Niu et al 2004;Caires et al 2008;Jordan-Meille and Pellerin 2008). To date, there are no detailed studies reporting root growth and biomass distribution profile in soil for oilseeds or pulses.…”
