Estudo da fertilidade dos solos de cobertura de um aterro sanitário do Estado do Ceará (Nordeste, Brasil)

<p class="yiv0149913358msonormal">This study was aimed to evaluate the fertility potential of a landfill cover soil in the State of Ceará (Northeastern Brazil) as a substrate for the survival and development of a vegetation cover. Four cover soil sampling points were chosen and simple samples were collected (500 g) at two different depths (0-20 cm and 20-40 cm), adding up to 16 samples (1st campaign: August 2014, 2nd campaign: December 2014) that were tested for 20 chemical attributes. Most attributes indicated a favorable condition for the survival and development of a vegetation cover. There was a major trend of decreased concentration of the tested attributes with depth, in agreement with the available literature. Considering that there are large trees in the studied area and no fallen trees were found, it seems that the cover soil has allowed for a good root fixation.</p>
