Causes and consequences of acid rain Discover them The soil is the skin of the earth, a mantle full of scars, thousand-year-old wrinkles and more recent injuries caused both by man and nature itself. Some of these ulcers are incurable — such as the extinction of species—, whereas oth...
The main environmental concern regarding linen production is the release of chemicals used in the retting process into surrounding ecosystems. Most commonly, alkali or oxalic acid are used to separate flax fibers from the woody interior of flax stems, and while chemical retting of flax is undeniab...
Ask wine lovers what the most complex grape is and often, you’ll hear about Pinot Noir. Ask growers which variety is the toughest to farm and you’re very likely to get the same answer. Pinot’s thin skin and relatively high acid make for nuanced and aromatically compelling wines, and...
This first stage produces simple molecules, which can then recombine to make more complex molecules if this astonishing experiment is successful. What we're going to do now is warm the system a little to see what the ice does.第一步产生简单的分子，如果这个惊人的实验成功的话，这些简单的分子就...
In situations such as Sub-Saharan Africa, where soil fertility is low and P removal exceeds average inputs of 2 kg P/ha/year, the resulting nutrient depletion severely restricts yields (e.g., maize yields < 1,000 kg/ha/year) and accelerates soil degradation. In other regions, excessive ...
This is what we now call acid rain. You’ve probably heard of it. But no one used the term back then. Anyway…the acid rain created highly acidic soil. Well, soon the soil became so acidic that nothing could grow, nothing at all. ...

What areas can be adversely affected by acid rain? Explain why the C:N ratio of a soil is important. How does the C:N ratio of added organic residue affect soil processes, especially decomposition? What is the effect of pesticides on run-off soil and what does the data suggest should ta...
Soil formation creates a dizzying array of soil horizons; here are just a few examples: Plinthite — which hardens irreversibly upon repeated wetting and drying (Figure 8a). Sulfidic — a horizon containing pyrite which, upon exposure to oxygen, can produce so much sulfuric acid that it kills...
