Similarly, a value of 7 on the pH scale represents neutral soil. Acidic soil is predominantly formed as a result of decomposition of plant and animal matter. Besides that, soil formed from an acidic parent rock will also turn out to be acidic soil.
Generally, you come across such soil in regions which have soft water or which experience heavy rainfall. This soil can also be transformed to alkaline soil as a result of various natural occurrences, including disintegration of a limestone rock.
Acidic Soil Plants
The simple rule of the thumb is that the plants which prefer acidic conditions grow well in acidic soil. The pH level of the soil determines the presence of different nutrients in it. If you try to plant species which prefer acidic soil in alkaline soil, it will indirectly affect their growth, as they will not be able to derive the necessary nutrients.
As in case of these plants, even microorganisms have a preference for either acidic or alkaline soil. So the pH level of soil has a crucial role to play when it comes to smooth functioning of the said ecosystem.
Some of these plants have beautiful flowers, which is what makes them quite popular among gardening enthusiasts. If you are looking forward to add some acidic soil loving plants to your garden, you should try some of the species we mentioned here.
If your region doesn't have soil with low pH level, you can resort to various methods of lowering soil pH, including some simple ones such as adding sulfur or composting. Similarly, if the soil in the area wherein you reside is too acidic for the plants to thrive, you can resort to neutralization of soil by adding agricultural lime or calcium sulfate to it.
