olf courses represent an agricultural activity wherein grass is intensively cultivated using large quantities of fer-
tilizers. In the present study, nitrogen and phosphorus leaching was analyzed over two years in an experimental
green under actual
fi
eld conditions. The green contained four plots with distinct amendments (P1: hydrogel
+ peat, P2: peat, P3: hydrogel, and P4: no amendment). The applied doses of nitrogen ranged from 5 to
103 kg/ha and of phosphorus from 9 to 31 kg/ha. The irrigation level varied as a function of the rainfall regime
and the water requirements of grass; overall water intake varied from 1550 to 2080 mm/year. Daily, leached
water volume was calculated, and samples were taken for chemical analysis. Nitrogen and phosphorus mass bal-
ances were calculated for different periods based on the collected data.
The plot amended with peat and hydrogel (P1) had reduced water
fl
ow; the percentage of drainage water varied
from 8.4 to 29%. As a result, the dissolution and leaching of nitrogen (N) and phosphorus (P) were the lowest in
comparison to the other plots. According to the calculated mass balances, the lowest leaching values were also
recorded in this plot (P1), ranging from 0.5 to 6.3% for N and from 0.8 to 20.9% for P. The plot without amendment
(P4) drained the most water (25.9
–
44.8%) and leached the highest quantities of N and P, ranging from 9.1
–
45.7%,
and 6

erating conditions for the green. Moreover, a relationship was found between increasing rates of fertilization and
increasing percentages of N and P leaching as well as between higher irrigation levels and greater leaching. [-]
