Última Diversity of arbuscular mycorrhizal fungi in a gypsum mining impacted semiarid area Acta Botanica Mergulhão,Adália Cavalcanti do Espírito Santo; Burity,Hélio Almeida; Goto,Bruno Tomio; Maia,Leonor Costa. The aim of this work was to evaluate the impact of gypsum mining on the occurrence and diversity of arbuscular mycorrhizal fungi (AMF). Soil samples were collected in the rainy and dry periods in four areas of a gypsum mine: native preserved "caatinga" (NC); mine vicinity (MS); reject area (RA); interface between the reject area and an area of "caatinga" degraded by mining (IN). Forty two plant species were identified in these areas; some were not found in both collection periods. Thirty six taxa of AMF were identified: 31 in the rainy and 31 in the dry period, with different species composition. Mining activity reduced diversity of plants and of AMF in the three mining areas when compared to NC. Plant similarity indexes were low between NC and the...

In this work, investigations were carried out with five treatments [control, three doses of lime stabilized sludge (60, 120, 240 Mg ha-1 dry base) and soil corrective plus mineral fertilizer] to evaluate the immediate recuperation of a borrowed area. The application of stabilized alkaline sewage sludge acted as an acidity corrective, allowed the increase in the organic matter contents (21 to 43.5g dm-3) and available P (44 to 156 mg dm-3). Even with the use of the highest dose, no increase in the concentration of 32 analyzed metals was observed, due to the low concentration of metals in the sludge. The experiment showed that short term restoration of degraded area was possible by using high rates of sewage sludge without metal contamination.
