Sometimes there could be too much aluminum in the soil making it acidic. Sometimes there is too much manganese which is toxic to plants. If the soil is too acidic, it can be because of a calcium and magnesium deficiency which is just as bad for plants as it is for humans. Iron and aluminum in great amounts can tie up phosphorus which also makes the soil too acidic for plants.

Garden soils will gradually become acidic as the rain that falls is slightly acidic and most fertilisers are also.
add calcium carbonate
A base such as lime.
To increase the pH level in the soil so that the soil does not become too acidic.

It is either naturally acidic or the rocks and minerals around it make it become acidic. This can be harmful to plants.
q Conifers make the soil they grow in too acidic for other plants too grow because when they let their needles die and fall to the soil, those needles have acidic substances so it goes into the soil making other plants not grow
add calcium carbonate
A soil is acidic because there are compounds within it which dissolve in water to form an acid. An acid is defined as a substance which readily gives out protons to oter molecules. An alkali is the converse, in that it is a proton acceptor and readily takes on protons. Treating an acidic soil with an alkali would neutralise the soil, and so the soil would become less acidic. If enough alkali is added, the soil will become neutral, and it will become alkaline if even more alkali is added.
