Abstract
Nucleic acids added to soils were readily degraded, producing organic orthophosphate. Quantitative and qualitative changes in the microbial populations of the soils accompanied the degradation. Adsorption of the nucleic acids by montmorillonite did not prevent degradation. Montmorillonite-DNA complexes were attacked in such a way that a uniform structural collapse occurred.
