Soil is a rather complex structure. Its relation with the processes of change provoked by industrial effluents can be explained through the modifications undergone in the biology of the soil. The objectives of this study were to evaluate the behavior of bioindicators (Mesofauna and Macrofauna) of the soil submitted to an irrigation with treated industrial effluent from a poultry slaughterer in an area reforested with Eucalyptus urophylla. The experiment was carried out in a reforestation area in western Paraná, Brazil. Sixteen plots were installed, four treatments: irrigation rate of 0, 100 m3, 200 m3 and 300 m3, with 4 replications each. The experimental design was constructed entirely by chance. From data collection methods, such as TSBF (Tropical Soil Biology and Fertility Method) and fall traps, the bioindicators were classified in the laboratory according to their order and family. Also coliforms were assayed at 35 ° C by depth counting technique (Petrifilm / 3M Coliform Counting Plate), based on AFNOR 01 / 2-09 / 89C. Through the introduction and use of tools of statistical quality control in the evaluation of some soil bioindicators it was possible to perform with this work to relate these indicators with attributes of soil fertility, in addition to identifying soil contaminant organisms present not being used in irrigation. CEP was useful in the monitoring of bioindicators, demonstrating that the local environment remained balanced in different volumes of effluent applied. |
