Visual soil structure quality and its correlation to quantitative soil physical properties of upland rice site in Falcataria moluccana agroforestry system

Abstract. Briliawan BD, Wijayanto N, Wasis B. 2022. Visual soil structure quality and its correlation to quantitative physical properties of upland rice site in Falcataria moluccana agroforestry system. Biodiversitas 23: 1894-1903. Sengon are plants that have the potential be combined However, development often results poor properties. Measuring soil’s is expensive complicated do by some people. This study aims measure visual from different land covers calculate parameters The research was conducted Cikabayan forest used purposive sampling method take samples. comparing nine form monoculture developed organic conventional agriculture with tropical rainforests as natural vegetation. Three samples were taken for each cover type analyzed a completely randomized design. showed vegetation rainforest generated best score on all measurement methods (VESS, GrassVESS Sq Rm). at highest porosity (57.303%). Meanwhile, monoculture-conventional bulk density (1.373 g.cm-3). VESS had compared other methods. Thus, cultivated most appropriate estimating
