Our hypothesis was that subsurface and well waters in watershed with shallow, stony soils, steep landscapes, and cropped to tobacco are contaminated by nitrate.
Nitrate in soil solution was monitored in (0.20 m) and below (0.5 m) root zone with tension lysimeters, in five transects.
Water from two wells (beneath tobacco field and in native forest) used for human consumption was also analyzed for nitrate.
Soil bulk density, porosity, and saturated hydraulic conductivity were evaluated.
Soil physical and hydrological properties showed great variation at different landscape positions and soil depths.
Soil coarse grain size, high porosity, and saturated hydraulic conductivity favored leaching nitrate.
Nitrate in soil solution from tobacco fields was greater than in natural environment.
Nitrate reached depths bellow rooting zone with values as high as 80 mg L−1 in tobacco plantation.
Water well located below tobacco plantation had high nitrate concentration, sometimes above the critical limit of 10 mg L−1.
Tobacco cropping causes significant water pollution by nitrate, posing risk to human health.
A large amount of nitrogen fertilizers applied to tobacco and nitrate in subsurface waters demonstrate the unsustainability of tobacco production in small farming units on steeps slopes, with stony and shallow soils.
