Effects of wood ash and N fertilization on soil chemical properties and growth of Zelkova serrata across soil types.

ABSTRACT: Wood ash generated as a by-product of biomass combustion can be a sustainable and reasonable approach to counteract acidification and correct nutrient deficiency in forest soils. We investigated the influence of wood ash (WA) and combined WA + N (nitrogen) on soil chemical properties, growth and foliar nutrients of Zelkova serrata and their potential as a soil amender across different soil types. We applied four levels of WA (0, 5, 10, and 20 Mg ha^-1) and two levels of N fertilizer (0 and 150 kg ha^-1) across three different soil types: landfill saline (LS) soil, forest infertile (FI) soil, and forest acidic (FA) soil. The WA generally improved soil pH, organic matter, available P, exchangeable cations (K⁺, Na⁺, Ca²⁺, and Mg²⁺
