Nodula Akar Pohon Casuarina glauca dan C. littoralis dan Nilai Akumulasi Nitrogen pada Tanah dibawahnya
Abstract
Ringkasan. Tulisan ini melaporkan hasil akumulasi Nitrogen tanah di bawah pohon Casuarina glauca dan C. littoralis dan sebagai bandingan di bawah pohon Banksia serrata di dalam ekosistim yang sama. Walaupun nilai jumlah akumulasi Nitrogen tanah di bawah pohon C. glauca dan C. littoralis rendah (di bawah 0.1 persen) ternyata ada perbedaan yang nyata antara kerapatan dan kepadatan vegetasi dibawahnya kalau dibandingkan dengan di bawah pohon B. serrata yang mempunyai nilai akumulasi Nitrogen tanah antara 0.0311-030523 persen.
Abstract. This paper, reports the measurement results of soil Nitrogen accumulation value under theCasuarinaglaucaand,C.littoralistrees and as a comparation under theBanksiaserratatrees of the some ecosystem. Though total soil Nitrogen accumulation value under theCasuarinaglaucaandC.littoralistrees are low (under 0.1 percent) there is a wide difference in density and coverage of vegetation under theBanksiaserratatrees which have a soil Nitrogen value between 0.0311-0.0523 percents.
