PENGARUH PEMBERIAN BAHAN ORGANIK PADA LUBANG RESAPAN BIOPORI MODIFIKASI TERHADAP KONTRIBUSI KETERSEDIAAN UNSUR HARA BAGI TANAMAN KELAPA SAWIT
Abstrak: The productivity of
palm oil plantations are generally still low compared to the potential
productivity of the land. Fertilization is an important factor in acheving high
productivity, mainly to meet the requirement of nutrient avaibility. The
research objective was to determine the avaibility of nutrient in oil palm
leaves from the application of organic matter in modified biopore infiltration
pit. This research was conducted in palm oil plantation PTPN 13 Pelaihari Tanah
Laut,in 2013 and 2014. Sample collection were done by taking a leaf on the 17th
oil palm midrib, which was taken using a purposively sampling spread system.
The results showed a low level of nutrient content of nitrogen, potassium, and
magnisium in plant leaf tissue in the palm oil plantation. Content of Phosfat
in optimum level, and Calcium elements found
in a state of excess.
