| abstract: The effect of the aluminum in root has been evaluated by linear and weight measurements, but remains to be understood about the influence of this element on branching configuration of the root system. This study had the objective to assess the aluminum toxicity in roots of 21-day-old seedlings of three forage legumes, Adesmia latifolia, Trifolium repens and T. pratense (Fabaceae), by topological analysis. The legumes were grown in Oxisol treated or not with dolomite lime, which resulted in two Al saturation and pH: (a) Al= 0 %, pH= 6.2; (b) Al= 16 %, pH= 4.8. Number of first-order roots, external links (magnitude), total links in the longest unique path (altitude), total links in the primary root (altitude of primary root), total exterior path... |

| Poultry manure is used as fertilizer in natura, but little is known about whether it contaminates the soil with pathogenic organisms. The aim of this study was to assess the effects of organic, organomineral and mineral fertilizers on soil contamination by enteric pathogens, using poultry manure as the organic fertilizer. Manure was applied in field experiments at rates of 7.0 ton. ha-1 (maize crop, 2008/2009), 8.0 ton. ha-1 (wheat crop, 2009) and 14 ton. ha-1 (maize crop, 2010/2011). Organomineral fertilizer was applied at the same rates but was comprised of 50% manure and 50% mineral fertilizer. At 30 and 70 days after fertilization, the organic fertilizer and the upper 0-5 cm layer of the soil were tested for the presence of helminth eggs and larvae and... |
