The processing of tomato (Solanum lycopersicum L.) is featured in the centerwest region of Brazil, especially the state of Goiás, which currently leads the national production. Soy (Glycine max (L.) Merrill) is the culture that has grown over the past decades, especially in the central regions of Brazil, in other words, in the Cerrado. It's an interesting succession of areas cultivated under irrigation management in winter crop, taking advantage of the residual fertilizer left by irrigated crops. The present work aims to evaluate the application of stabilized fertilizers and slow release in partial or total replacement of conventional NPK fertilizer in cultivation of industrial tomato and its residual effect on soybean in crop rotation, evaluating by the determination of the related attributes productivity. The study was performed in field's condition in a Distrofic Red Latosoil clay soil in the experimental area of the School of Agronomy in Goiania – Goias. The experiment was conducted in the years 2011 and 2012 in a randomized complete block design with seven treatments and five repetitions. Conventional fertilizer NPK 04-30-16 fertilizer and partially coated with polymers and stabilized with DMPP was used. The source of fertilizer was applied only in the culture of industrial tomatoes associated with tillage. In the 2011/2012 season there was no reapplication and used tillage system without tillage. Sampling of soil and leaf were taken at flowering crops. It is concluded that partial replacement of NPK fertilizer at planting for fertilizers with DMPP responds with significant result for productivity. When complete replacement of fertilizer DMPP via soil is performed the result is not significant for yield. Of soybean crops in succession to growing tomatoes no residual effect of fertilizer was observed for productivity.
