Última Nutrients And Heavy Metals In Maize, Fertilized With Rock Phosphate And Biosolid 107 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...

The experiment was conducted in Eutrophic Red-Yellow Ultisol, and aimed to evaluate soil chemical properties in ICLF systems compared with other types of soil use. The study assessed ICLF systems, monocultures of acacia (Acacia mangium), Eucalyptus (Eucalyptus urophylla x E. grandis), Urochloa Brizantha, Urochloa decumbens, Sorghum bicolor and Panicum maximum, with crop variations in three agricultural cycles in a 2 year period, compared to native vegetation, 8-year-old U. Brizantha pasture and degraded pasture of P. maximum with areas of exposed soil. Compared to native forest and well-managed pastures and ICLF systems, contents of organic matter and calcium in the soil were lower in monocultures of eucalyptus, acacia and forage. The fact that the soil...
