Acid Rain Effects on Plant Growth
These are the similar occurrences brought about by acid rain on farm lands used for crop vegetations. Acid rain strips arable land of the nutrients needed to sustain the growth and propagation of crops. However, unlike forest soil, which does not receive aid from human intervention, farm lands are treated with soil lime in order to counter the indirect effects of acid rain on the crops.
Yet laboratory results related to studies of the effects of acid rain produced mixed results. These prevented scientists and chemists alike to pinpoint the exact causes of crop failure. A few theories offered include the premise that some plants and trees have stronger tolerance to acid depositions of sulfuric and nitric acids.
Another possibility is that the combined effects of acid rain with O3 or the bad ozone, formed due to the chemical reaction of nitrogen oxide with Volatile Organic Compound or VOC. The greatest degree of degradation take place in urban areas, where large concentrations of O3 are found. On the other hand, the high elevation of forests brings the plants and trees nearer to the O3 in the atmosphere which is in fact called, ground level ozone layer.
There is no doubt that acid rain effects have caused the environment great amounts of distress. In fact, infrastructures and human health conditions have also shown considerable damages from the accumulated and combined effects of pollution and acid rain. Although counter measures and regulations against acid rain effects on plants and trees are being implemented, the greater question is, how many more trees or even forests will die before those measures could result to positive effects?
