Última Nutrients And Heavy Metals In Maize, Fertilized With Rock Phosphate And Biosolid Engenharia na Agricultura Rodrigues, Marcio Neves; Sampaio, Regynaldo Arruda; Zuba Junio, Geraldo Ribeiro; Oliveira, Agda Loureiro Gonçalves. This study aimed to evaluate effects of rock phosphate and sewage sludge compound fertilization in level of contents of heavy metals and nutrients in two consecutive cultivation of corn grain. The project was conducted in an Haplic Cambisol on a period of days between April 10, 2009 and September 15, 2010. The treatments in factorial scale 2 by 4 meters corresponds to application on the first corn cultivation of 2 doses of rock gafsa phosphate (0 and 90 kg ha-1 of P2O5) and 4 compound doses of sewage sludge (0; 25; 50 and 75 t ha-1, in dry specimen). The experiment followed random blocks design with three treatments repetition. The fertilization with rock phosphate increased the levels of N, P, K and Mg only in the first corn grain cultivation and did not...
