Kajian Pengaruh Penundaan Waktu Pengeringan, Jenis Alat Pengeringan, dan Penyimpanan Contoh Daun terhadap Kandungan Hara Tanaman Kelapa Sawit (Elaeis guineensis Jacq.)

Abstract

Proper handling of oil palm leaf samples prior to laboratory analysis is for ensuring accurate nutrient analysis results. This study aims to compare the nutrient content of oil palm plants in response to differences in the storage of oil palm leaf samples before drying, the delay in drying time, and the type of oven used. The oil palm trees used in this study were 12 years old. The results showed that delaying the drying time of oil palm leaf samples from 12-year-old plants for Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, and Boron can be done for up to three days after field collection. Pre-drying storage of the leaves does not necessarily require refrigeration, and a conventional oven can be used for drying oil palm leaf samples
