Abstract:
This research was carried out in two different location in coffee tree
plantation sites located in São Miguel do Anta, State of Minas Gerais. The experiment
consisted in colecting soil samples at three soil layers, in two different sites of the coffee
tree plantation. One of the coffee tree plantation site a standard cultivation has been
carried out, and in the other site a weekly irrigation was applied during four months, by
sprinkling liquified swine manure. Physical and chemical analysis were maid using the
soil samples. The results showed that the pH and the levels of aluminium, copper and
iron in the soil did not change when the swine manure was applied. On the other hand,
the levels of the nitrogen, phosphorus, potassium, calcium, magnesium, manganese and
zinc increased in all soil layers studied. The level of sulphur increased in the two upper
layers.
