		<abstract>Changes in the chemical composition, with depth and time, of the soil water solution that results from rainfall and that percolates through the unsaturated zone, are studied after the slashing and burning of two "Terra Firme" Amazonian forest parcels located (9o57'42.20""S, 56o20'52.05""W) near Alta Floresta, MT. The samples were collected with zero tension lisymeters installed in the following parcels: (i)pristine forest, (ii)forest with the litter accidentally burned, (iii)and (iv)slashed and burned forest, in 1999 and 2001, respectively. The concentrations of Na+, K+, Mg2+, Ca2+, NH4 +, Cl-, NO3 -, SO4 2-, Fe2+, Mn2+, Cu2+, Zn2+ and Al3+ in the soil solution were determined. The major cations and anions presented a concentration decrease with time, after initial peaks caused by the burning, while for most metals a mobilization was observed. Also, unbalances which decrease with time were evidenced by the electronegativities determined. The pulses introduced in the soil solution composition lasted about two months for each major ion, and react with the soil system.</abstract>
