| Sumario: | The effect produced by the addition to the soil of a continuously renewable organic matter source (Nostoc muscorum Ag.) on the stability of soil aggregation and other physico-chemical and biological properties responsible for soil aggregation were determined. The inoculated soil shows an increase of 56 % of aggregates bigger than 250 μ and a decrease of 18.3 % of aggregates smaller than 2 μ. This stability is a consequence of the increase in the microbiological activity and also of the concentration of polysaccharides (mainly produced by the cyanobacteria) in the soil. |
