The objective of this study was to detwermine leaching
losses of Ca, Mg, K and nitric N in banana soils. The work
was conducted between 2003-2004 in the Venecia Farm in
Matina, Limón, Costa Rica. Three nitrogen fertilizer sources
were used: urea (U), ammonium nitrate (aN) and ammonium
sulfate (HS). Sampling was conducted at a depth of 60 cm
using lysimeters and the volume of percolated water (D) was
calculated using the indirect method of soil water balance
(BHs). Irrespective of the sampling dates no statistical differences
were determined found for pH. The concentration of
calcium (Ca) in the leachate for different treatments during
different times of sampling, was not significant, but significant
differences were found between treatment with U with
respect to treatment of NA and SA. No differences between
the NA and SA or in the average concentrations of magnesium
(Mg) and potassium (K) in the leachate were observed.
In the case of nitric nitrogen, significant differences were
detected only between the NA regarding the U and SA, both
in general and between sampling dates.
