Terra Rossa (soil)
Terra rossa (Italian for "red soil") is a well-drained, reddish, clayey to silty soil with neutral pH conditions and is typical of the Mediterranean region. The reddish color of terra rossa is the result of the preferential formation of hematite over goethite. This soil type typically occurs as a discontinuous layer that ranges from a few centimeters to several meters in thickness that covers limestone and dolomite bedrock in karst regions. The high internal drainage and neutral pH conditions of terra rossa are a result of the karstic nature of the underlying limestone and dolomite.Torrent, J., 2005. ''Mediterranean soils.''

Malvasia Vine On Terra Rossa Soil
Malvasia (, also known as Malvazia) is a group of wine grape varieties grown historically in the Mediterranean region, Balearic Islands, Canary Islands and the island of Madeira, but now grown in many of the winemaking regions of the world. In the past, the names Malvasia, Malvazia, and Malmsey have been used interchangeably for Malvasia-based wines; however, in modern oenology, "Malmsey" is now used almost exclusively for a sweet variety of Madeira wine made from the Malvasia grape. Grape varieties in this family include Malvasia bianca, Malvasia di Schierano, Malvasia negra, , Malvasia nera di Brindisi, Malvasia di Candia aromatica, Malvasia odorosissima, and a number of other varieties. Malvasia wines are produced in Greece (regions of Peloponnese, Cyclades and Crete), Italy (wine), Italy (including Friuli-Venezia Giulia, Lombardia (wine), Lombardia, Apulia, Sicily, Lipari, Emilia-Romagna, and Sardinia), Slovenia (wine), Slovenia, Croatia (including Istria), Corsica (wine), ...

USDA Soil Taxonomy
USDA soil taxonomy (ST) developed by the United States Department of Agriculture and the National Cooperative Soil Survey provides an elaborate classification of soil types according to several parameters (most commonly their properties) and in several levels: ''Order'', ''Suborder'', ''Great Group'', ''Subgroup'', ''Family'', and ''Series''. The classification was originally developed by Guy Donald Smith, former director of the U.S. Department of Agriculture's soil survey investigations. Discussion A taxonomy is an arrangement in a systematic manner; the USDA soil taxonomy has six levels of classification. They are, from most general to specific: order, suborder, great group, subgroup, family and series. Soil properties that can be measured quantitatively are used in this classification system – they include: depth, moisture, temperature, texture, structure, cation exchange capacity, base saturation, clay mineralogy, organic matter content and salt content. There are 12 soil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luvisols
The Canadian System of Soil Classification is more closely related to the American system than any other, but they differ in several ways. The Canadian system is designed to cover only Canadian soils. The Canadian system dispenses with the sub-order hierarchical level. Solonetzic and Gleysolic soils are differentiated at the order level. History Before 1955, Canadian soil testing was based on systems of classification which were similar to methods being used in the United States. In 1955, a taxonomic system of soil classification specific to Canadian conditions was introduced. This system was designed to differentiate soils created by pedogenic processes in cool climatic environments. Classification process The land area of Canada (excluding inland waters) is approximately 9 180 000 km2, of which about 1 375 000 km2 (15%) is rock land. The remainder is classified according to the Canadian System of Soil Classification. This system differentiates soil types on the b ...

Food And Agriculture Organization
The Food and Agriculture Organization of the United Nations (FAO)french: link=no, Organisation des Nations unies pour l'alimentation et l'agriculture; it, Organizzazione delle Nazioni Unite per l'Alimentazione e l'Agricoltura is an international organization that leads international efforts to defeat hunger and improve nutrition and food security. Its Latin motto, ', translates to "let there be bread". It was founded on 16 October 1945. The FAO is composed of 195 members (including 194 countries and the European Union). Their headquarters is in Rome, Italy, and the FAO maintains regional and field offices around the world, operating in over 130 countries. It helps governments and development agencies coordinate their activities to improve and develop agriculture, forestry, fisheries, and land and water resources. It also conducts research, provides technical assistance to projects, operates educational and training programs, and collects data on agricultural output, produ ...

FAO Soil Classification
The Food and Agriculture Organization of the United Nations (FAO) developed a supra-national classification, which offers useful generalizations about pedogenesis in relation to the interactions between the main soil-forming factors. It was first published in form of the UNESCO Soil Map of the World (1974) (scale 1 : 5 M.). Many of the names offered in that classification are known in many countries and do have similar meanings. Originally developed as a legend to the Soil Map of the World, the classification was applied by United Nations sponsored projects. Many countries modified this system to fit their particular needs. The Soil Units (106) were mapped as Soil Associations, designated by the dominant soil unit: * with soil phases (soil properties, such as saline, lithic, stony), * with three textural classes (coarse, medium, and fine) * three slopes classes superimposed (level to gently undulating, rolling to hilly, and steeply dissected to mountainous) The 106 Soil Units for ...

Soil Classification
Soil classification deals with the systematic categorization of soils based on distinguishing characteristics as well as criteria that dictate choices in use. Overview Soil classification is a dynamic subject, from the structure of the system, to the definitions of classes, to the application in the field. Soil classification can be approached from the perspective of soil as a material and soil as a resource. Inscriptions at the temple of Horus at Edfu outline a soil classification used by Tanen to determine what kind of temple to build at which site. Ancient Greek scholars produced a number of classification based on several different qualities of the soil. Engineering Geotechnical engineers classify soils according to their engineering properties as they relate to use for foundation support or building material. Modern engineering classification systems are designed to allow an easy transition from field observations to basic predictions of soil engineering properties and ...

Pedology (soil Study)
Pedology (from Greek: πέδον, ''pedon'', "soil"; and λόγος, ''logos'', "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment. Pedology is often seen as one of two main branches of soil inquiry, the other being edaphology which is traditionally more agronomically oriented and focuses on how soil properties influence plant communities (natural or cultivated). In studying the fundamental phenomenology of soils, e.g. soil formation (aka pedogenesis), pedologists pay particular attention to observing soil morphology and the geographic distributions of soils, and the placement of soil bodies into larger temporal and spatial contexts. In so doing, pedologists develop systems of soil classification, soil maps, and theories for characterizing temporal and spatial interrelations among soils . There are a few note ...
