Resumo
With urban growth also increases without waste disposal that need to be reused as the tannery
sludge and wastewater. Thus, the tanning humus sludge and wastewater are possible to be added
to the soil. The objective was to evaluate the effect of tannery sludge vermicompost in the
chemical properties of soil cultivated with tomato and irrigated with wastewater. The
experimental design was completely randomized in a factorial 6 x 2, totaling twelve treatments
with three replications. The treatments were: four tannery sludge vermicompost (25% Sludge
tannery(LC) + manure - T1, 25% Sludge tannery(LC) + rice husk - T2; 50% Sludge tannery(LC)
+ manure - T3 and 50% Sludge tannery(LC) + cane gray - T4), conventional fertilization (T5) and
control (without fertilization - T6) and two types of irrigation water (water supply and
wastewater). The physico-chemical characteristics and chemical soil and vermicompost
(fertilizers) were determined before the culture of the installation vessels and after ninety days of
driving the tomato crop. Three homogeneous samples were collected, with about 300 g of each
vessel. The data were submitted to analysis of variance by F test and comparisons between
treatment means were performed by 5% Tukey test. In general, concentrations of chemical
parameters in the soil after addition of vermicompost have increased, particularly in the addition
of T2 = 25% LC + 75% of rice husk and T4 = 50% LC + 50% cane gray. Thus it can be
concluded that vermicompost used can be added to soil conditioners changing the soil chemical
attributes positively.
