16S rRNA V4 soil pyrotags in five different timepoints from the same place. soil metagenome

Metagenomic analysis of agricultural disturbed and undisturbed soils using 454 pyrosequencing technology. These analysis comprise both whole genome shotgun and 16S amplicon sequencing, in order to study metabolic function and taxonomic composition of this environment. This project consists of the analysis of cropped and uncropped soils from an agricultural field in Argentina. Soil samples were taken during a one year wheat/soybean rotation under no-till farming and during the same year in grassland nearby. This is the first large scale 16S rRNA survey made on Argentinean agricultural soils, and one of the biggest surveys of this kind done in the world. Argentina is one of the biggest agricultural world producers, having one of the largest and more fertile lands. This dataset could be used as a good reference for agricultural soil biodiversity.
