The monitoring of the sheetflow erosion in different land uses, Uberlândia - MG

When the soil erosion is accelerated by Humankind action, occur a lot of environmental and economic problems, just because the soil erosion has influence in environment stability. This research was developed at Glória Experimental Farm/UFU, and its objective was to make analyses and comparisons between pluvial soil erosion in seven different land uses. It was collected data about soil moisture, runoff, sediments transport and images from each land use in different times for making the photo-comparison to study the development of the vegetations. In this research were used erosion plots with slope of 5º and a trough in its end part for collecting the water and sediments transported. As a first result, it was observed that any kind of vegetal cover helps in erosion decrease because of the interception of rain drops and the soil radiation by the vegetation leaves. It is possible to affirm that the runoff transports the sediments and the nutrients of soil, and so, the soil cover becomes inappropriate to the agriculture and for another uses.
