| dc.description.abstract | LENI: Study of physical and chemical soil characteritics in oil palm plantation with
several vegetations that grow in Tanah Raja PTP Nusantara III. Supervised by
SUMONO and NAZIF ICHWAN
Physical and chemical soil characteritic is an important factor for the
growth of oil palm. This research is aimed to study physical and chemical soil
characteritics on the oil palm with vegetation such Mucuna bracteata, Nephrolepis
biserrata, grass and without vegetation in Tanah Raja PTP Nusantara III. The
observed parameters are soil texture, porosity, water content of field capasity, soil
permeability, total Nitrogen, available soil Phosphate, and land Potassium
exchange.
The results showed that the soil type was ultisol with sandy clay loam texture
and pH ranged from 4.95 to 5.29 (sour). The soil vegetation’s porosity was 50.44 to
52.21% at 5 cm depth and 46.86 to 46.96% at 25 cm depth. The water content of
field capacity was ranged from 32.12 to 38.98%. Permeability was ranged from 4.57
to 6.01 cm/h at 5 cm depth and 2.21 to 3.69 cm/h at 25 cm depth. N total was ranged
from 0.11 to 0.12%. P available was ranged from 12.87 to 18.96 ppm. K exchange of
land was ranged from 0.56 to 0.61 me/100g. The soil without vegetation’s porosity
was 46.91% at 5 cm depth and 45% at 25 cm depth. The water content of field
capacity was 31.54%. Permeability was 2.86 cm/h at 5 cm depth and 1.84 cm/h at 25
cm depth. Total N was 0.09%. P available was 10.75 ppm. K exchange of land was
0.55 me/100g | en_US |
