Analysis of Physical and Electrical Properties on Peat Soils in Longan Plantations in West Kalimantan Region

Abstract

Peatlands in the vast area of West Kalimantan can be utilized especially in Kubu Raya Regency is the Longan plantation. This study aims to determine soil fertility based on the physical and electrical properties of the soil. The parameters to be examined are specific gravity using ASTM method D-854-02 Pycnometer, EC value using conductivity meter, Cation Exchange Capacity (CEC) using Titrimetry/PU 3011 method, and C-Organic using Spectrophotometry method. Based on the results of the study it was found that the KL 1 sample had a specific gravity of 0.28 gcm-3, a CEC of 28.61 me 100g-1, and C-Organic of 42.14%. In the sample KL 2 has a specific gravity of 0.38 gcm-3, CEC of 15.79 me 100g-1, and C-Organic 14.16%. EC values have a range of 0.01 - 0.19 dSm-1. The results showed that the physical and electrical properties of the soil can be used to determine soil fertility.
