Kajian Kontaminan Nitrogen Dan Fosfor Di Areal Perkebunan Kelapa Sawit Ptp. Nusantara Iv Kebun Pabatu Pada Musim Hujan

Abstract

SANTO ALFONSIUS TINAMBUNAN : Nitrogen And Phosphorus Contaminants Assessment in Oil Palm Plantation Pabatu Area of PTP. Nusantara IV During Rainy Season. Supervised by SUMONO and NAZIF ICHWAN. The use of land within a Sub River Flow Area that is intended for oil palm plantations that has fertilization treatment and the effect of rainfall can cause erosion of some elements of soil nutrient, such as Nitrogen and Phosporus in the water body causing contamination. Nitrogen and Phosphorus Contaminants in the water body of the river will depend on the river water discharge. Therefore study is needed on total nitrogen and total phosphorus to determine the extent of nitrogen and phosphorus that come flowing into rivers and river discharge relationship with total nitrogen and phosphorus. The resulst showed the total amount of nitrogen in the Sei Kalemba Sub River Flow Area (Padang river Flow Area ) was 1,39 – 11,74 mg/litre and the total amount of phosphorus in the Sei Kalemba Sub River Flow Area (Padang river Flow Area ) was 2,01 – 7,96 mg/litre. Total Nitrogen and Phosporus in th Sei Kalembae Sub River Flow Area (Padang river Flow Area ) showed that was a relationship with river water discharge.
