Conteúdo: | Based on the increasing trend in the consumption of granulated organic mineral fertilizers (OMF) in Brazil, it's concluded which the insertion of the product in the domestic market depends mainly on technological advances. Investment in technologies it's makes necessary to meet the market demand with products of proven quality, which will provide differentials attractive, such as: the supply of essential nutrients or micronutrients for agricultural production and adequation of mechanized application. These fertilizers have an excellent environmental and economic appeal, since they are an alternative for the use, as raw material, of agro-industrial residues that can be enriched with mineral fertilizers containing phosphorus (P), micronutrients and/or other nutrients of agricultural interest. This work aimed to evaluate the diffusion of phosphorus present in OMF by the Petri dish bench methodology, fast and non-destructive, in samples of sandy soil, collected in Seropédica, RJ. Two OMF were used, produced at Embrapa Solos from different carbon sources, containing MAP in its formulation, in relation to mineral fertilizer (MAP). The effect of doses of P on the OMF and MAP granulate and the effect of the incubation time on the diffusion of P were evaluated. The results indicated that at least 4 mg of P per fertilizer sample is required for greater efficiency of the detection methodology used. The source of raw material used in the production of the OMF did not interfere in the diffusion of P having a diffusive behavior similar to MAP.
