As the DM production was increased in the range of slides were evaluated, it is understood
that not worked with the blade that maximizes the productivity of the grass, but the values
are higher than those quoted by Mitidiere (1983) and Correa (1999), demonstrating that there
is no restriction on the use of wastewater for irrigation and fertilization of grass. He also
noted that there is a direct relationship between height and DM yield of grass.

mean of WW applied in the area (L).
Evaluating the results shown in Figure 2 it is observed that in the 0 to 0.20 m estimates of Sb
according to AR applied blades reach a maximum of increase of 0.212 cmol c dm- 3 to the
blade of 200 mm and the layer 0.20 to 0.40 m depth Sb maximum, .802 cmol c dm -3 was
estimated with the blade of 270 mm.
It is also observed that the addition of Sb was higher in the layer of 0.20 to 0.40 m in depth
and that the reduction of Sb in the descending part of both curves results in leaching of the
bases for the deeper regions of the soil.
