Chestnut has no strict soil requirements and is suitable for growing on sandy loam soil with deep soil, good drainage and low groundwater level. The rich soil humus is conducive to mycorrhizal growth. Soils generated from parent materials such as granite and gneiss, sandy soils and even clay loams with good physical and chemical properties, rich in organic matter, fertilizer and water retention, and pH 4.5 to 7.6 are suitable for cultivating chestnut trees. However, pH 5.6 to 6.5 is optimal. pH7.6 is the adaptive limit. If this value is exceeded, chestnut trees will grow poorly or even die.
