Precipitation: What Which Factors Affect Soil Ph?

There are many factors that effect soil pH such as precipitation, burning fossil fuel and parental materials in which the soils form from. Precipitation is one of the major factors that effect soil pH. Higher precipitation will cause the soil pH to decrease because Calcium and Magnesium gets leached away from the soil. Acid rain can also cause a significant change in the soil pH and this is caused by such things as gases produced when burning fossil fuel. When the acidifying elements remain in the gases produced, acid rain will occur causing the soil pH to decrease and become more acidic which leaches many of the soil nutrients. Parental materials such as limestone or sandstone which contribute to the soil production can determine the acidity or the alkalinity of the soil. Soils formed by sandstone will be more acidic than soil formed by limestone. The native vegetation can also effect the soil pH. Roots growing produce CO2 as well as acid and areas of native grass tend to be less acidic than soil formed under areas of forests. These are all factors which can effect the soil pH and such changes in the soil pH can affect the vegetation. Different plants get affected differently by the acidity of the soil so it is significantly important to understand the relationship between a plant species with its favorable pH range.

Hiroshima prefecture of Japan has suffered such environmental threats in the past which were caused by industrial pollutants which were carelessly being emitted into the atmosphere. If such air pollution can have an effect on the growth of trees, PM2.5 could certainly be having a negative effect on the health of pinetrees in
