Rondon de Rodriguez C. | Ruiz M. | Elizalde G.
The microaggregates (50-250 4m) of six soils, of two savanna landscapes of Guarico state, have high concentrations of Si, Al, Fe; half contents of Na, Mg, Ca, P, Cu, Zn, C, N; and drop, concentrations of alterable minerals. The content of carbon of Fulvic Acid (FA) is similar to the carbohydrates and the carbon of Humic Acid (HA) is bigger than FA. According to possibilities of bonds between organic and inorganic matter, the components of microaggregates can be put in order in this manner,--ARC-AH-MPOL-ARC-AF-ARC-C-MPOL--; where ARC is the active mineral, AF the fulvic acid, MPOL the polyvalent metal, C the carbohydrate and AH the humic acid. The models of formation of microaggregates in soils of temperate regions, carried out in soils of tropical regions, with the dissimilitudes of the chemical activity of plasma.
