Chitemene
Chitemene (also spelled citemene), from the ciBemba word meaning “place where branches have been cut for a garden”, is a system of slash and burn agriculture practiced throughout northern Zambia. It involves coppicing or pollarding of standing trees in a primary or secondary growth Miombo woodland, stacking of the cut biomass, and eventual burning of the cut biomass in order to create a thicker layer of ash than would be possible with in situ burning. Crops such as maize, finger millet, sorghum, or cassava are then planted in the burned are Description Chitemene systems are most widely used throughout the Central Zambezian Miombo woodlands that is the largest ecoregion in Zambia and the predominant ecoregion of Northwestern, Copperbelt, Central, Northern, and Luapula provinces. Typical soils in this biome are of the order oxisols, which are highly weathered, acidic, and easily leached soils. The pH of these soils range from 4.0 to 4.5, values too acidic for the cultivat ...

Plenitude
The principle of plenitude asserts that the universe contains all possible forms of existence. Arthur Lovejoy, a historian of ideas, was the first to trace the history of this philosophically important principle explicitly. Lovejoy distinguishes two versions of the principle: a static version, in which the universe displays a constant fullness and diversity, and a temporalized version, in which fullness and diversity gradually increase over time. Lovejoy traces the principle of plenitude to the writings of Plato, finding in the ''Timaeus'' an insistence on "the necessarily complete translation of all the ideal possibilities into actuality". By contrast, he takes Aristotle to reject the principle in his ''Metaphysics'', when he writes that "it is not necessary that everything that is possible should exist in actuality". Since Plato, the principle of plenitude has had the following adherents: *Epicurus reiterated the principle in fr.266 Us. His follower Lucretius (''DRN'' V 526- ...

Paucity
In economics, scarcity "refers to the basic fact of life that there exists only a finite amount of human and nonhuman resources which the best technical knowledge is capable of using to produce only limited maximum amounts of each economic good."Samuelson, P. Anthony., Samuelson, W. (1980). Economics. 11th ed. / New York: McGraw-Hill. If the conditions of scarcity didn't exist and an "infinite amount of every good could be produced or human wants fully satisfied ... there would be no economic goods, i.e. goods that are relatively scarce..." Scarcity is the limited availability of a commodity, which may be in demand in the market or by the commons. Scarcity also includes an individual's lack of resources to buy commodities. The opposite of scarcity is abundance. Scarcity plays a key role in economic theory, and it is essential for a "proper definition of economics itself."Montani G. (1987) Scarcity. In: Palgrave Macmillan (eds) ''The New Palgrave Dictionary of Economics''. Palgra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaonde Chitemene P
Kaonde (''kiiKaonde'') is a Bantu language spoken primarily in Zambia but also in the Democratic Republic of the Congo. Kaonde and its dialects are spoken and understood by perhaps 350,000 people or more. It is estimated that approximately 2.3% of Zambians are native Kaonde speakers. Kaonde speakers overwhelmingly live in the Northwestern and parts of Central regions of Zambia. Fewer numbers of Kaonde speakers live in the Democratic Republic of the Congo. However, they are not known or identified by the term Kaonde but rather by the term Luba. In Zambia, Kaonde people occupying the following districts: Solwezi,Mufumbwe,Kasempa,Kalumbila and Mushindamo in the North-Western province, and Mumbwa in the Central province. Kaonde villages can also be found in the northern parts of Kaoma District in the Western Province. Just like any other tribe in Zambia, Kaondes are ruled by the traditional leaders. The following are the chiefs of the Kaonde people recognised by the government of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millet
Millets () are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa. Millets are important crops in the semiarid tropics of Asia and Africa (especially in India, Mali, Nigeria, and Niger), with 97% of millet production in developing countries. This crop is favored due to its productivity and short growing season under dry, high-temperature conditions. Millets are indigenous to many parts of the world. The most widely grown millets are sorghum and pearl millets, which are important crops in India and parts of Africa. Finger millet, proso millet, and foxtail millet are also important crop species. Millets may have been consumed by humans for about 7,000 years and potentially had "a pivotal role in the rise of multi-crop agriculture and settled farming societies." Descript ...

Soil Fertility
Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.Bodenfruchtbarkeit Retrieved on 2015-11-09. It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.A fertile soil has the following properties: * The ability to supply essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and * The absence of toxic substances which may inhibit plant growth e.g Fe^2+ which leads to nutrient toxicity. The following properties contribute to soil fertilit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tilth
Tilth is a physical condition of soil, especially in relation to its suitability for planting or growing a crop. Factors that determine tilth include the formation and stability of aggregated soil particles, moisture content, degree of aeration, soil biota, rate of water infiltration and drainage. Tilth can change rapidly, depending on environmental factors such as changes in moisture, tillage and soil amendments. The objective of tillage (mechanical manipulation of the soil) is to improve tilth, thereby increasing crop production; in the long term, however, conventional tillage, especially plowing, often has the opposite effect, causing the soil carbon sponge to oxidize, break down and become compacted. Soil with good tilth is spongy with large pore spaces for air infiltration and water movement. Roots only grow where the soil tilth allows for adequate levels of soil oxygen. Such soil also holds a reasonable supply of water and nutrients. Tillage, organic matter amendments, fert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil PH
Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( or, more precisely, ) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as ), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH 9) are rare. Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element i ... ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxisols
Oxisols are a soil order in USDA soil taxonomy, best known for their occurrence in tropical rain forest within 25 degrees north and south of the Equator. In the World Reference Base for Soil Resources (WRB), they belong mainly to the ferralsols, but some are plinthosols or nitisols. Some oxisols have been previously classified as laterite soils. Formation The main processes of soil formation of oxisols are weathering, humification and pedoturbation due to animals. These processes produce the characteristic soil profile. They are defined as soils containing ''at all depths'' no more than ten percent weatherable minerals, and low cation exchange capacity. Oxisols are always a red or yellowish color, due to the high concentration of iron(III) and aluminium oxides and hydroxides. They also contain quartz and kaolin, plus small amounts of other clay minerals and organic matter. Etymology The word "oxisol" comes from ''"oxide"'' in reference to the dominance of oxide minerals such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
