WebMay 3, 2024 · Nitrate-based fertilizers have no acidification potential and actually can increase soil pH as one H⁺ ion is absorbed by the plant (or OH⁻ excreted) in the uptake of nitrate. In high pH soils (pH >7.2), dissociation of H+ ion from the H₂PO₄⁻ molecule will generate some acidity. Soil acidity and P fertilizers. Will fertilizer lower pH? WebFeb 27, 2024 · The application amount of fertilizer is believed to dramatically influence soil bacteria in paddy fields, and soil bacteria critically affect soil enzyme activities and the growth of rice in paddy fields.
