Resumo: The addition of urban waste in the soils can promote environmental modifications. A field experiment on a soil (Paleudult) was carried out to evaluate some physical and microbiological characteristics after continuous applica- tion of doses of municipal solid waste (MSW) compost. Progressive doses of MSW compost (0, 20, 40, 80, and 160 t ha–1) and one dose of mineral fertilizer were tested on soil for a three years period. The results obtained showed that when the amount of compost increases, soil density decreases, whereas aggregates stability increases under rain until 80 t ha–1 of compost. The number of colony forming units of bacteria increased according to the compost dosage althou- gh the populations of actinomyces and fungi were not affected. In conclusion, the application of 80 t ha–1 of MSW com- post was the recommended dose for the maintenance of physical and microbiological characteristics of agricultural soil.

Em virtude disso, este trabalho teve o objetivo avaliar as alterações em algumas propriedades físicas e microbioló- gicas do solo sob adição contínua de composto de lixo urbano. O experimento a campo foi conduzido em um solo clas- sificado como Argissolo Vermelho de textura média na Estação Experimental Agronômica da UFRGS. Os tratamentos constaram de cinco aplicações contínuas pelo período de três anos de diferentes doses de composto (0, 20, 40, 80 e 160 t ha–1) e de uma dose de fertilizante mineral. Após a adição de composto no solo observou-se que a densidade do solo diminuiu com as doses aplicadas e aumentou a estabilidade de agregados sob chuva até a dose de 80 t ha–1. A quantidade de bactérias aumentou até um determinado limite, enquanto os fungos e actinomicetos não apresentaram um aumento significativo em relação às doses aplicadas. Os resultados permitiram concluir que aplicações de até 80 t ha–1 ano–1 de composto de lixo urbano podem ser consideradas como a taxa de utilização agrícola, recomendada com o objetivo de melhorar e manter as propriedades físicas e microbiológicas do solo. Departamento de Diagnóstico e Pesquisa Agropecuária.
