New enlightenment on the regulatory effects of acids and phenolic compounds in wood vinegar, a by-product of biomass pyrolysis, on tomato production.

ABSTRACT: Wood vinegar (WV), a biomass pyrolysis by-product, is widely used in agriculture because of the complexity and abundance of its bioactive substances. However, the specific mechanisms underlying plant growth regulation by acids and phenolic compounds, accounting for the largest proportion of their constituents, remain unclear. Therefore, the main acids (N-ethylglycine, Lactic, and 2-pyridinecarboxylic acids) and phenols (Catechol and Guaiacol) were selected to understand their effects on soil properties, microbial communities, and tomato growth in a pot experiment. Results showed that individual applications of acids and phenolics significantly enhanced nutrient availability (e.g., soil AP, AK, and AN), promoted tomato growth (e.g., PH, SD, AB), and regulated endogenous hormone levels (upre
