Soil microbial community structure and function of agriculturally used Mollisols in the periurban area around Buenos Aires, Argentina, with emphasis on pesticide and heavy metal contamination
… agriculture and the maintenance of sustainable soil fertility are of essential importance. However, the population is increasingly concerned about an environmental contamination because of an enhanced application of pesticides and heavy metal containing fertilisers in the course of which organic …

Transport of copiotrophic bacteria in oligotrophic coarse soils: a Monte Carlo analysis
… systems placed in coarse-grained, oligotrophic soils such as those typically found in the mountainous regions of the West are designed and installed with the assumption that most pathogenic microorganisms will not pass unaltered through an unsaturated zone located in the soil below each system. …

Using Arbuscular Mycorrhizae to Influence Yield, Available Soil Nutrients and Soil Quality in Conventional VS. Organic Vegetable Production
… if mycorrhizae improve yield, available soil nutrients and soil quality from two different fertilizer sources. Measurements were taken on yield, available soil nutrients, and soil quality in comparison of glomalin production and soil loss percentage. Two plant species were chosen, …

Studies of genera cytophaga-flavobacterium in context of the soil carbon cycle
… cycle; with specific interest in the cycling of soil carbon. This need is two-fold and interconnected. The global climate change is in-part due to the loss of soil organic carbon and the reduced ability of soils to sequester carbon. Also, to maintain sustainable, high yielding agriculture, carbon …

Purification and Characterization of Proteolytic Aspartate Transcarbamoylase (ATCase) from Burkholderia cepacia 25416 and Construction of a pyrB1 Knock-out Mutant
Burkholderia cepacia is a common soil bacterium of significance in agriculture and bioremediation. B. cepacia is also an opportunistic pathogen of humans causing highly communicable pulmonary infections in cystic fibrosis and immunocompromized patients. The pyrB gene encoding ATCase was cloned and …
