| | Soil |
 | | The organic part of soils is derived chiefly from the remains of vegetables and animals which have lived and died in and upon the soil, which have been spread over it by rivers and rains, or which have been added by the industry of man for the purposes of increased fertility. | | | All clayey soils require great industry and care, as well as a considerable portion of knowledge in dressing or management to keep them in good condition; yet when their natural toughness is got the better of, they always yield the heaviest and most abundant crops. | | | Clayey soils, when sufficiently enriched with manures, are naturally well qualified for carrying crops of wheat, oats, beans, and clover; but are not fitted for barley, turnips, potatoes, etc., or even for being kept under for grass longer than one year. |

| | Soil science |
| | Soil science deals with soil as a natural resource on the surface of the earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils per se; and these properties in relation to the use and management of soils. | | | One interesting effort drawing in soil scientists in the USA as of 2004 is the Soil Quality Initiative. | | | Indeed, engineers, agronomists, chemists, geologists, geographers, biologists, microbiologists, sylviculturists, sanitarians, and specialists in regional planning, all contribute to further knowledge of soils and the advancement of the soil sciences. |

| | 18th World Congress of Soil Science - Symposia |
| | Soil degradation is a serious global issue in terms of sustainability of ecosystem productivity and economic and social aspects, leading to a decline in soil quality and net primary productivity, pollution and eutrophication of natural waters, and emission of greenhouse gases into the atmosphere. | | | Global and regional trends in productivity, soil fertility and nutrient use efficiency will be analyzed. | | | The severity of the soil problems is often overlooked because low productivity is considered to be due to low rainfall. |

| | soil type: Information From Answers.com |
| | Soil is made up in part of finely ground rock particles, grouped according to size as sand, silt, and clay. | | | However, ""soil type"" in the broader sense refers to a pedological classification of the natural (or human-influenced) soil. | | | In agriculture, soil type usually refers to the different sizes of mineral particles in a particular sample. |

| | 5. CLASSIFICATION |
| | Soils are classified as Histosols, if either more than half of the upper 80 cm of soil is organic, or if organic soil material of any thickness rests on rock or fragmental material having interstices filled with organic materials. | | | Soil Taxonomy also recognizes humilluvic materials, which is illuvial humus accumulating in the lower horizons of some acid organic soils where they have been drained and cultivated. | | | The mean annual soil temperature is 8°C or higher and there is a difference of less than 5°C between the mean summer and mean winter soil temperatures at a depth of 30 cm. |

| | Histosol - Art History Online Reference and Guide |
| | In both the FAO soil classification and the USA soil taxonomy, Histosols are soils comprised primarily of organic materials. | | | Most are acidic and many are very deficient in major plant nutrients which are washed away in the consistently moist soil. | | | Like Gelisols, Histosols have greatly restricted use for engineering purposes because structures tend to subside in the wet soil. |

| | Oxisol - Network Live |
| | The main processes of soil formation of oxisols are weathering, humification and pedoturbation due to animals. | | | This forces plants to get their nutrition from decaying litter as oxisols are quite infertile due to the lack of organic matter and the almost complete absence of soluble minerals leached by the wet and humid climate. | | | Because the present climate can never produce enough weathering to produce oxisols, torrox soils are always paleosols formed during periods of much wetter climates. |

| | Pedons generally are sampled by horizon rather than by arbitrary depth increments because soil horizonization provides a physical model for the physical and chemical development of the soil. | | | [1] The pedon is the smallest physical sampling unit of a soil (generally from 1 to 10 square meters in area and as deep as the soil is formed) required to describe the variability in the properties of that soil at a specific location (Soil Survey Staff, 1999). | | | U.S. Department of Agriculture, Natural Resources Conservation Service, 2001, National Soil Characterization Database, accessed September 1, 2001, at URL http://ssldata.nrcs.usda.gov/. |
