Acidity and soil nutrient availability:
What observations can you make based on your interpretation of the graph below? what happens to nutrient availability when soils become more acidic or alkaline.
Given that plants can alter the pH of soil by addition of organic acids ( i.e.. conifer needles which are very acidic) how may they use this strategy competitively?
How does man's intervention with acidic deposition affect our forests, grasslands? how might this affect wildlife in the long run? Already animals show nutrient deficiencies which are altering bone and physiological processes in Sweden.
