Kajian Kontaminan Nitrogen dan Fosfor di Sub Das Sei Kalemba (Das Padang) Areal Perkebunan Kelapa Sawit PTP. Nusantara IV Pabatu pada Musim Kemarau

Abstract

KIKI Fadli: Contaminants Assessment Nitrogen And Phosphorus In Sub Das Sei Kalemba (Das Padang) Area of Oil Palm Plantation PTP. Nusantara IV Pabatu In the dry season. Guided by Sumono and AINUN ROHANAH. The reduced organic matter content in multiple use of land allocated to oil palm plantations. Damage due to erosion resulting in erosion of some elements of soil fertility, such as nitrogen and phosphorus elements and the use of fertilizers which will go into water bodies resulting in contamination. Nitrogen and phosphorus contaminants in river water bodies will depend on the flow of river water. It is necessary for the study of total nitrogen and total phosphorus to determine the extent of nitrogen and phosphorus that come flowing into rivers and river discharge relationship with table Nitrogen and Phosphorus table. The results showed the total nitrogen content in the subzone Sei Kalemba (DAS Padang) in may of 0 to 5.59 mg / liter and the content of total phosphorus in the subzone Sei Kalemba (DAS Padang) obtained for 1.82 to 55.53 mg / liter. Total Nitrogen (TN) in the subzone Sei Kalemba (DAS Padang) did not show any inclination relationship with bulk hujan.Total Phosphorus (TP) in the subzone Sei Kalemba (DAS Padang) shows the tendency that the relative relationship with the rainfall, although not linear.
