Be Healthy With Organic Food

Motivations For Organic Agriculture ... Consumer surveys have consistently identified food quality as the main reason for purchasing organic food... Higher nutritional value, no toxic residues from pesticides, and better taste are often cited, as is the positive impact of organic production on the environment... Whether organic food actually delivers on these desires and beliefs is controversial and the subject of scientifically inconclusive debate...

Soil Conservation ... Decisions regarding appropriate crop rotation, cover crops, and planted windbreaks are central to the ability of surface soils to retain their integrity, both with respect to erosive forces and chemical change from nutrient depletion. Crop rotation is simply the conventional alternation of crops on a given field, so that nutrient depletion is avoided from repetitive chemical uptake/deposition of single crop growth...

Organic Movement ... Organic food was initially seen as a fad observed by the eccentric few, however today it has become more widespread...

Genetically Modified Organism ... In 1986, field tests of bacteria genetically engineered to protect plants from frost damage (ice-minus bacteria) at a small biotechnology company called Advanced Genetic Sciences of Oakland, California, were repeatedly delayed by opponents of biotechnology. In the same year, a proposed field test of a microbe genetically engineered for a pest resistance protein by Monsanto Company was dropped...

Organic Farming Methods ... Organic farming uses a variety of methods to improve soil fertility, including crop rotation, cover cropping, reduced tillage, and application of compost... By reducing tillage, soil is not inverted and exposed to air; less carbon is lost to the atmosphere resulting in more soil organic carbon... In contrast, organic farming tends to tolerate some pest populations while taking a longer-term approach...

Electric Vehicle ... Electric vehicles first came into existence in the mid-19th century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time. The internal combustion engine (ICE) is the dominant propulsion method for motor vehicles but electric power has remained commonplace in other vehicle types, such as trains and smaller vehicles of all types...

Sustainable Agriculture ... The most important factors for an individual site are sun, air, soil and water. Of the four, water and soil quality and quantity are most amenable to human intervention through time and labour...

Callisto (moon) ... Compounds detected spectroscopically on the surface include water ice, carbon dioxide, silicates, and organic compounds...

Soil PH ... Below pH 4, H+ ions themselves damage root cell membranes. In soils with high content of Manganese (Mn) containing minerals, Manganese toxicity can become a problem at pH 5.6 and below...

Soil Retrogression And Degradation ... At the beginning of soil formation, the bare rock out crops is gradually colonized by pioneer species (lichens and mosses). They are succeeded by herbaceous vegetation, shrubs and finally forest...

Organic Certification ... fertilizer, pesticides, antibiotics, food additives, etc.), genetically modified organisms, irradiation, and the use of biosolids; use of farmland that has been free from prohibited synthetic chemicals for a number of years (often, three or more); keeping detailed written production and sales records (audit trail); maintaining strict physical separation of organic products from non-certified products; undergoing periodic on-site inspections... In some countries, certification is overseen by the government, and commercial use of the term organic is legally restricted... Certified organic producers are also subject to the same agricultural, food safety and other government regulations that apply to non-certified producers...

Climate Change And Agriculture ... At the same time, agriculture has been shown to produce significant effects on climate change, primarily through the production and release of greenhouse gases such as carbon dioxide, methane, and nitrous oxide, but also by altering the Earth's land cover, which can change its ability to absorb or reflect heat and light, thus contributing to radiative forcing. Land use change such as deforestation and desertification, together with use of fossil fuels, are the major anthropogenic sources of carbon dioxide; agriculture itself is the major contributor to increasing methane and nitrous oxide concentrations in Earth's atmosphere...

Hydrogen Economy ... Hydrogen advocates promote hydrogen as a potential fuel for motive power (including cars and boats), the energy needs of buildings and portable electronics. Free hydrogen does not occur naturally in quantity, and thus must be generated from some other energy source by steam reformation of natural gas or another method...

Thin Film Solar Cell ... Thin-film solar cells are usually categorized according to the photovoltaic material used: Amorphous silicon (a-Si) and other thin-film silicon (TF-Si) Cadmium Telluride (CdTe) Copper indium gallium selenide (CIS or CIGS) Dye-sensitized solar cell (DSC) and other organic solar cells Possible combinations of Group-(XI, XIII, XVI) elements in the periodic table that yield a compound showing photovoltaic effect (Cu, Ag, Au | Al, Ga, In | S, Se, Te)...

Hydrogen Storage ... Most research into hydrogen storage is focused on storing hydrogen as a lightweight, compact energy carrier for mobile applications. Liquid hydrogen or slush hydrogen may be used, as in the Space Shuttle...
