| الملخص: | The study was carried out at Dusun Durian Estate, Golden Hope Plantations
Berhad Banting, Selangor, in a 50 ha plot which represents a coastal oil palm
plantation. The general objective of this study was to obtain accurate and timely
information about the spatial distribution and status of nutrients in the soil and leaf
tissue using Geographic Information System (GIS) and remote sensing technology
for precision farming of oil palm plantation. Collection of soil and leaf tissue data
were conducted by using systematic sampling and an Omni Star DGPS was used to
precisely determine the sample sites location. Geostatistics (GS+) software and
classical statistics were used for data analysis. A SPOT image of K-J.299344
acquired on March 2000 from the Malaysian Centre for Remote Sensing (MACRES)
was analysed using a PCI software version 7.0. Descriptive statistical analysis
classed the status of total N as low, whereas available P and exchangeable K varied
from moderate to high. Soil exchangeable Ca and Mg ranged from low to moderate.
Soil nutrients variability of available P, exchangeable K, Ca and Mg status were
classified as high and moderate for total N. Semivariance analysis showed that the |
