Abstract

Long bean (Vigna sinensis L.) is a legume widely cultivated for its high nutritional
value and economic importance. However, marginal podzolic soils in regions such
as Riau, Indonesia, pose challenges for sustainable agriculture due to low nutrient
availability and high acidity. This study evaluates the integration of quail manure and
natural phosphate fertilizers as a sustainable soil management strategy to enhance
