High values of BD lead to low soil porosity and high soil compaction, causing restrictions to root growth, poor movement of air and water through the soil and influencing crop yield (Çelik et al., 2021). Furthermore, by reducing water infiltration into the soil, compaction can lead to increased runoff and soil erosion (Liao et al., 2015).

Acids can lower the pH of the soil, preventing plants and soil microorganisms from thriving, and can also react with various minerals in the soil that are required by plants, such as calcium and magnesium. The hydrogen ions from the acid absorb the soil particles, preventing other nutrients required by plants to remain in the soil.
