Herein we describe a new fertilizer delivery system made of thermoplastic starch composite used to control the release of nitrogen in greenhouse trials. The innovative in this work is to used a natural matrix to disperse the N source followed by one extrusion processing step that is easily scalable. The extrudate was formed into a continuous strand using a rod die and was subsequently air-cooled and pelletized. The extrusion process yielded homogeneous pellets with high nitrogen content that could be applied directly to the soil. Melamine changed the structure of composites and also loading the N final content of the fertilizers. Soil incubaton experiments showed that urea was released more controlled by the matrix reaching the same N proportion of urea after 28 days assay. Greenhouse trials revealed that melamine plays an important role as structure modifier, increasing the effective use of available of urea for maize in pot experiments. It was also verified that the Nmelamine was not available at the first 60 days of the trial experiment, showing that the lower amount of nitrogen released (only from urea) was better utilized by the plants in the composite configuration. The pelletized composite could be a prospective system for smart fertilization processing based on a renewable source (e.g. starch). |
