Sour soils

Air in soil has a different composition from the air we breathe. Normal dry air at sea level contains about 21% oxygen (O2) and 0.04% carbon dioxide (COg). In soil the percentile of oxygen may drop to as low as 15%, and the percentage of carbon dioxide may rise above 5%. This results from the partial oxidation of organic matter in the closed space. The carbon in the organic material combines with oxygen to form carbon dioxide. This increased concentration of carbon dioxide tends to cause groundwater to become acidic acidic soils are described as sour soils because of the presence of aqueous acids. 

There was no sign of my supernatural feline helper out in the calle. Feeling soiled and with a sour taste in my mouth, I hurried back through the dark to the watersteps where Giorgio was waiting. If I had just thrown away fifty ducats, Nostradamus would skin me. 

The greater the amount of carbon dioxide in soil, the more hydronium ions and so the lower the pH. Soil that has a low pH is referred to as sour. (Recall from Chapter 10 that many acidic foods, such as lemon, are characteristically sour.) Two main sources of soil carbon dioxide are humus and plant roots. The humus releases carbon dioxide as it decays, and plant roots release carbon dioxide as a product of cellular respiration. A healthy soil may have enough carbon dioxide released from these processes to give a pH range from about 4 to 7- If the soil becomes too acidic, a weak base, such as calcium carbonate (known as lime or limestone), can be added. 

Only for light soils, otherwise some trees die after 6-10 years, including sour cherries. Highly susceptible to damage by mice, little root suckering, frost-hardy.

Cherries need full sun and. especially for sweet cherries, well-drained soil. Choose a site free of late spring frosts. Train sweet cherries to a central leader form and sour cherries to an open center form. For more pruning information, see "Pruning and Training" on page 101.

Solutions of certain common salts of strong acids are acidic. For this reason, many home-owners apply iron(II) sulfate, FeSO, 7H2O, or aluminum sulfate, Al2(S04)3 I8H2O, to the soil around acid-loving plants such as azaleas, camelias, and hollies. You have probably tasted the sour, acid taste of alum, KA1(S04)2 I2H2O, a substance that is frequently...

Sulfur isotope compositions are employed to assess the effect of industrial activities in pristine environments, particularly in regions where the pollutant sulfur has a distinct d S value compared to that of the environmental receptors. For example, in the province of Alberta, Canada, emissions from sour gas processing plants have d S values 201 higher compared to sulfur isotope compositions of unaffected soils. The distinct isotope composition of the anthropogenic sulfur allows it to be followed as it enters the environment via biogeochemical reactions. 

Its clusters are medium-sized and conical, with a wing at the base of the rachis. Berries are medium-sized, rounded and of a deep blue to black colour with a fine waxy coating. Sufficient ripeness can be reached only in outstanding localities. It requires very sunny, sloping tracts of land. Kofranka requires soils of medium quality. It does not like dry sites because lack of water can inhibit its growth. However, too wet soils are also not suitable. Kofranka is a late cultivar and ripens in the second half of October. The wine is an intense, deep red colour. The aroma is dominated by dry plums, sour cherries and forest berries. It is a full-bodied and extractive wine.
