Performance of three Dicotyledon Species on Lead/Zinc Mine Spoil with Various Nitrogen Sources
Abstract:
Rapid leaching of nitrogen fertilizers is a factor limiting the long term success of
revegetation on the Trelogan mine spoil due to the physical structure of mine waste
material, with its almost total lack of organic matter. A slow release nitrogen fertilizer was
examined, in addition to fast release sources, to assess its performance. Single and split
doses of conventional nitrogen fertilizers were also used to compare their effects. Shoot
and root dry weight of Rumex acetosa was greater than control at a single and split
application of NaNO3 and only root dry weight of Minuartia verna was improved at the
single dose of NaNO3 and (NH4)2SO4. In contrast there was no effect of single and split
doses of urea and NH4NO3 and the single application of slow release source (Golden-N) on
the growth characters of Plantago lanceolata when compared to control. Split doses of
conventional fertilizers were more effective than single doses.
