Integrated GIS and GPS for mapping of land suitability for Multy Purpose Tree Species (Persea americana) at community agroforestry land in Peria-ria Village

Abstract

Persea americana is known as the Multy Purpose Tree Species (MPTS), which comes from the Lauraceae family. In community agroforestry land in Deli Serdang Regency. The objective of this study was to map the suitability of land for Persea americana in Peria-ria Village. This research was conducted using survey methods. Soil samples are collected from survey results in the field based on land units, then the coordinates were marked using the Global Positioning System (GPS). To create a map of land suitability class distribution, Geographic Information System (GIS) technology was used. In land suitability study, were adopted from the Soil and Agro-climate Research Centre, Bogor, West Java, Indonesia, namely: references and land suitability criteria for Agricultural Plants. The actual land suitability for Persea americana is not suitable (N) (98.55%) and marginally suitable (S3) (1.45%) and potential land suitability for Persea americana is marginally suitable (S3) (1.45%) and moderately suitable (S2) (98.55%) in Peria-ria Village, Biru-Biru Sub district. Water availability (wa), erosion hazard (er) and root zone media (rc), were limiting factors. The most difficult constrain to overcome were the root zone medium and water availability.
