Attributes of dystrophic latosol in southern minas gerais after application of sewage sludge

In general, tropical soils present low natural fertility, which results in a great amount of degraded areas if it is associated with improper handling. Sewage sludge, due to its high levels of organic matter and nutrients, can improve soil properties. Thus, this study evaluated the conditioning and...

Description
Summary:	In general, tropical soils present low natural fertility, which results in a great amount of degraded areas if it is associated with improper handling. Sewage sludge, due to its high levels of organic matter and nutrients, can improve soil properties. Thus, this study evaluated the conditioning and fertilizing effects of sewage sludge on the attributes of a typical dystrophic latosol in Southern Minas Gerais. The experiment evaluated the application of sludge from Santana wastewater treatment plant in Varginhas (Minas Gerais, Brazil) in pots, with concentrations equivalent to 60, 120, and 180 t ha-1, and a control treatment without sludge. The sewage sludge has increased the levels of organic matter, cation-exchange capacity, sum of the bases and nutrients, as well as increased porosity and decreased soil density, thus indicating the potential for conditioning and fertilizing agricultural soils.
