| Abstract/Contents: | [English] "The chemical characteristics of a soil cultivated with Tifton 85 grass (Cynodon spp.) after receiving different urban solid waste (MSW) leachate rates were evaluated. A 5,000 L reservoir, filled with new MSW was used to produce the leachate used in the research. The leachate was applied at rates of 0, 250, 500, 750, 1000 kg ha-1 day-1 of BOD. The pH, the content of organic matter (OM), N-total, NO3-, NH4+, available P and exchangeable concentrations of K, Ca, Mg, Mn were measured. Soil Cationic Exchange Capacity (CEC) was also determided by calculation. It was found that MSW leachate application raised soil N-total, K, P, NO3- and Mn concentrations. MSW leachate rates less than 750 kg ha-1 day-1 of BOD provided no elevation of contaminant concentrations to critical levels during the experiment period and, therefore, these rates can be used. However, we recommend a long term monitoring of soil chemical characteristics and groundwater in order to assess environmental contamination risks if disposal was done outside landfill." [Portuguese] "Avaliaram-se as características químicas de um solo cultivado com capim Tifton 85 (Cynodon spp.) após aplicação de diferentes taxas de percolado de resíduo sólido urbano (RSU). Empregou-se um reservatório de PVC, com capacidade de 5.000 L, preenchido com RSU novo, para produzir o percolado utilizado na pesquisa. O percolado foi aplicado a taxas de 0, 250, 500, 750, 1000 kg ha-1 dia-1 de DBO. Mediram-se o pH, o conteúdo de matéria orgânica (MO), N-total, NO3-, NH4+, P disponível e as concentrações trocáveis de K, Ca, Mg, Mn. Determinou-se por cálculo a capacidade de troca catiônica (CTC) do solo. Verificou-se que a aplicação do percolado de RSU proporcionou aumento na concentração de N-total, K, P, NO3- e Mn do solo. A utilização de percolado de RSU a taxas inferiores a 750 kg ha-1 dia-1 de DBO não causou elevação das concentrações dos contaminantes a níveis críticos, durante o período experimental e, portanto, podem ser utilizadas. Entretanto, é recomendável um monitoramento de longo prazo das características químicas do solo, bem como das águas subterrâneas para que se avaliem os riscos de contaminação ambiental se a disposição for feita em área externa ao aterro sanitário." |
