Efeito do efluente de suíno na condutividade hidráulica de um solo compactado.

Abstract

The physico-chemical characteristics of West Paraná region soil (very clayey, with little organic matter and of compaction easy) show a potential to hydraulic conductivity reduction. In this paper, the alterations in the soil compacted permeability in different soil moisture and application swine wastewater. Soil columns were needed to experiment: in the base 0,03 m of soil was compacted (soil moisture 28%, 32% and 36% ± 1%) and in the superior part 1,10 m of: effuent (raw swine wastewater, diluted swine wstewater and water) with three repetitions. The soil organic matter was conduced by dicromate method. The results show a reduction of the seepage with the application of raw swine wastewater and tend the colmatation after 15 days. The soil organic matter not were significance variability attributing at the clogging of the soil pores with colloidal particles.
