Humic-like Substances Extracted from Hydrochar as an Additive for Foliar Fertilization in Tomato Plants.

ABSTRACT: Biomass reuse and the development of fertilization strategies are approaches for enhancing agricultural productivity. Humic-like substances (HLS), extracted from hydrochars of various biomasses, exhibit valuable characteristics such as diverse organic composition and nutrient complexation, which can stimulate plant growth. However, few studies have investigated HLS as a foliar fertilization application. In this work, HLSs were extracted from two hydrochars derived from sugar cane bagasse and vinasse: HLS_A (additive H₃PO₄) and HLS_B (additive KOH), which were then characterized. HLSs were applied by foliar spraying at 50, 100, and 300 mg of TOC L^-1, with and without fertilizer in tomato plants (Solanum lycopersicum L.). Plant development was monitore
