Homework Answers
Acidification results in decrease of cations .
Decrease in pH or acidification of soil is due to acidic precipitation in soil like sulphur dioxide , nitric and ammonia . It causes reduction in cation exchange capacity and also water takes basic elements along with it . pH of pure rain is less acidic with a pH of between 5-6 . But heavy rain pH is near about 4 . Due to heavy rain nutrients in soil run off and is not available for plants .

1. When lime is added to an acid soil, explain what it does to 1) soil pH (and what is the mechanism by which it changes the pH); 2) cation exchange capacity (Hint: Think back to pH-dependent charge to understand the effect on cation exchange capacity.) and; 3) the composition of exchangeable cations. 2. Why do some soils need more lime to raise their pH than other soils? Explain your answer in terms of buffering capacity, and active vs. reserve...

A major loss occurs when stage III plants are removed from media and moved to soil in pots where they die before selling to the public. How is “acclimitazation” and “hardening off” achieved/what steps can be taken to toughen up plants and roots before (at stage III) and after (stage IV) being placed in soil?

Investigative Extensions 1. Earthworms are among the most familiar inhabitants of soil. They play an important role in improving the texture of and adding organic mat- ter to soil. You may have read Darwin's estimate that over 50,000 earth- worms may inhabit one acre of British farmland. Earthworms are readily available from biological supply houses, or you may collect your own to use in experiments. Following are questions that you might investigate. a. Why do earthworms come out of their...

3. Unpolluted rain has an approximate pH of 5.5. Natural emissions (from volcanoes and lightning), and human activity (from mining and industrial plants) emit compounds that mix with water vapor in the atmosphere to create "acid rain," which can have a pH-4.5. Referring to the pH equation, explain why decreasing pH numbers mean that the acidity is increasing. a. Referring to the pH equation, explain why more acidic solutions have lower pH values. b. Referring to the pH equation, explain...
