When I began my studies for the certificate in the NY Botanical, soil science was one of the most difficult classes, it covers a whole universe. If it seems too much of text book information, you are right. If you know a lot about the subject, go ahead, skip it. Stick around or buy the book. Keep it as a reference, it will be useful for your gardening life.
Soil is a living creature with lots of secrets. Forgotten and ignored for a simple reason, when bare, is not so attractive except for geologists and archeologists.
MICROORGANISMS
Bacteria, simple one-celled organisms are the most abundant inhabitants in the soil. Up to 100 million organisms may live in one
teaspoon of soil. Common soil bacteria are rod-shaped, though many assume other shapes. Bacteria usually grow as small colonies
on the surface of soil particles and smaller pores. They are most dominant in nonacid soils.
Bacteria are the most variable of soil organisms. While most are aerobic, many thrive in anaerobic soil. Most are heterothropic, yet many obtain energy autothropically from chemical reactions with certain soil substances.
Most soil bacteria are saphrophytic. They comprise one of the groups most responsible for breaking down organic matter in the soil. A few species are parasites, causing plant diseases such as crown gall (Agrobacterium tunfasciens) which causes a tumorlike
growth on roots of many plants.
One of the issues that keep yours truly motivated to keep a blog, was the destruction of 5 hectares in the town of Trujillo Alto, by a Phd and his wife. Alberto Areces Mallea and Gabriella Ocampo, the culprits. http://antigonumcajaneveningpost.blogspot.com/2011/06/parque-dona-ines-alberto-areces-mallea.html, there is a whole series of articles on that scam if you are interested.
