What is true about acidic soil?

Acidic soil is characterized by having a pH value that is less than 7.0. This lower pH level indicates a higher concentration of hydrogen ions in the soil, which can affect nutrient availability and plant growth. Many crops thrive in slightly acidic conditions, with optimal pH ranges typically falling between 6.0 and 6.8. Soil acidity can influence the solubility of certain nutrients and minerals, impacting their availability to plants.

In contrast, a pH greater than 7.0 indicates alkaline soil, which can lead to different nutrient deficiencies and plant health issues. A neutral pH, being exactly 7.0, is often considered ideal for many crops but does not represent the conditions of acidic soil. Furthermore, while some crops prefer acidic conditions, not all crops benefit from it; many require neutral or slightly alkaline soils to thrive. Thus, the statement that acidic soil has a pH less than 7.0 accurately describes its characteristics.
