Occurrence of Azospirillum brasilense in soils amended with swine manure
Restriction analysis of amplified 16S rDNA from bacterial strains isolated from soil was used to evaluate the effects of swine manure and urea fertilisation on indigenous populations of the plant growth promoting bacterium, Azospirillum brasilense, in corncultivated experimental plots. Several operational taxonomic units (OTUs) were found among the isolates. One of them, identified as A. brasil...
متن کاملAn Alternative Approach to Assess the Habitat Selection of Folsomia candida in Contaminated Soils.
Avoidance tests with collembolans provide a quick assessment of soil quality. However, some parameters of the procedure can be modified in order to increase its performance. In this study we assessed the tendency of Folsomia candida to avoid soils contaminated with boric acid [350-700-1400-2800-5600 mg/kg soil dry weight (dw)], phenmedipham (35-70-140-280 mg/kg dw) or petroleum hydrocarbons (13...
متن کاملEffects of liquid swine manure applications on NO3–N leaching losses to subsurface drainage water from loamy soils in Iowa
Long-term applications of organic or inorganic sources of N to croplands can increase the leaching potential of nitrate– nitrogen (NO3–N) for soils underlain by subsurface drainage ‘‘tile’’ network. A field study was conducted for 6 years (1993– 1998) to determine the effects of liquid swine manure and urea ammonium nitrate (UAN) solution fertilizer applications on NO3–N concentrations and NO3–...
متن کاملComparative ecotoxicity of three polluted industrial soils for the Collembola Folsomia candida.
We tried to quantify the ecotoxicity of three industrial soil samples contaminated by different metals, using the Collembolan Folsomia candida as a biological model and mortality, growth and reproduction as parameters. The observed ecotoxicities are rather normal for the first such soil sample (aluminum factory) but are high for the second sample (ore treatment) and relatively low for the third...
