Status of soil quality in various agroforestry systems in banyurip village jenar district sragen regency

Abstract

Agroforestry consists of various land covers that produce litter, which results in the addition of organic matter to the soil and improves soil quality. This study aims to determine the status of soil quality in various agroforestry systems by calculating the soil quality index in various agroforestry systems. This research was conducted in Banyurip Village, Jenar District, Sragen Regency, Indonesia. This research was conducted on various agroforestry systems, namely teak agroforestry, teak-sacha inchi agroforestry, and sacha inchi monoculture, as well as land that does not apply agroforestry systems. A total of nine indicators were used, and then the indicators were tested with principal component analysis using Minitab 18 to select the minimum data set. The indicators were chosen as soil humidity, bulk density, porosity, CEC, soil total N, soil organic C, and microbial biomass C. The highest soil quality indexes in teak agroforestry and teak-sacha inchi agroforestry were 0.22. The highest soil quality index in teak agroforestry and teak-sacha inchi agroforestry each was 0.22, and the soil quality index in sacha inchi monocultur was 0.20. The soil quality of the three types of agroforestry is low because the soil quality index ranges from 0.2-0.39.
