AI Technical Summary
Existing technologies for wood vinegar fermentation fertilizer have low fermentation efficiency, long fermentation time, low content of effective ingredients, and unstable effects on soil salinity and pH, which limits the effectiveness of saline-alkali land improvement.
Wood vinegar fermentation fertilizer, composed of pretreated humic acid, modified intercalated montmorillonite, sodium lignosulfonate, rare earth solution, and fermentation products, improves fermentation efficiency and enhances soil microbial activity through specific stirring, homogenization, heat preservation, and freezing treatments combined with a fermentation process at specific temperature and humidity.
It significantly improves soil structure, reduces soil salinity, enhances soil permeability and water and fertilizer retention capacity, promotes crop growth, and increases crop yield and stress resistance.
