Summary A gas lysimeter study showed negligible losses of gaseous N2 or N2O from rhodes grass plants growing in soil fertilized with either (N15H4)2SO4 or KN15O3; isotope recovered from the soil: plant system averaged respectively 100.5% and 98.9%; neither differed significantly from 100%. Small amounts of ammonia were volatilized into lysimeter atmospheres, averaging 0.6% of that applied as labelled ammonium-N and 0.1% of that as nitrate-N. The importance of these findings is discussed in relation to the conduct of N balance studies.
