Above the stem plate is the storage organ consisting of bulb scales, surrounding the previous flower stalk and the terminal bud. The scales are of two types, true storage organs and the bases of the foliage leaves.
Sustainable development of world food supplies impact the future of globalization and the long-term survival of the speciesso care must be taken to ensure that agricultural methods remain in harmony with the environment. Farmlands in Hebei province, China. Definition Agri is from Latin ager "a field"and culture is from Latin cultura, meaning "cultivation" in the strict sense of "tillage of the soil.
The term agriculture may also refer to the study of the practice of agriculture, more formally known as agricultural science.
The history of agriculture is closely linked to human historyand agricultural developments have been crucial factors in social changeincluding the specialization of human activity. Agriculture is by far the most common occupation, employing 42 percent of the world's laborers.
However, agricultural production accounts for less than five percent of the gross world product an aggregate of all gross domestic products. Farming refers to a wide range agricultural production work, covering a large spectrum of operation scales acreage, output, and so forthpractices, and commercial inclination.
At one end of this spectrum, the subsistence farmer tills a small area with limited resource inputs, and produces only enough food to meet the needs of his or her family.
At the other end of the spectrum is commercial intensive agriculture, including industrial agriculture. These operations generally attempt to maximize financial income from produce or livestock. Farming with a tractor in Sweden. Modern agriculture extends well beyond the traditional production of food for humans and animal feed.
Other agricultural production goods include cut flowersornamental and nursery plants, timberfertilizersanimal hides, leather, industrial chemicals starchsugarethanolalcoholsand plasticsfibers such as cottonwoolhemp, and flaxand biofuels such as methanol and biodiesel.
Animals, including horsesmulesoxencamelsllamasalpacasand dogsare often used to cultivate fields, harvest crops, and transport farm products to markets. Animal husbandry involves breeding and raising animals for meat or to harvest animal products like milk, eggs, or wool on a continual basis.
Mechanization has enormously increased farm efficiency and productivity in Western agriculture. The twentieth century saw massive changes in agricultural practice, particularly in agricultural chemistry.
Agricultural chemistry includes the application of chemical fertilizerchemical insecticides, and chemical fungicides, soil makeup, analysis of agricultural products, and nutritional needs of farm animals. Beginning in the Western world, the "green revolution" spread many of these changes to farms throughout the world, with varying success.
Tea plantation in Java, Indonesia.
Engineers have developed plans for irrigationdrainage, and sanitary engineering, particularly important in normally arid areas that rely upon constant irrigation, and on large-scale farms.
The packing, processing, and marketing of agricultural products are closely related activities also influenced by science. Methods of quick-freezing and dehydration have increased the markets for farm products. Airplaneshelicopterstrucksand tractors are used in Western agriculture for seeding, spraying operations for insect and disease control, aerial topdressing, and transporting perishable products.

Radio and television disseminate vital weather reports and other information such as market reports that concern farmers. Computers have become an essential tool for farm management.
According to the National Academy of Engineering in the United Statesagricultural mechanization is one of the 20 greatest engineering achievements of the twentieth century.
By the end of the century, due to advances in agricultural technology, a single farmer could feed over people. This has come at a cost, however. A large energy input, often from fossil fuelis required to maintain such high levels of output.
Other developments in agriculture include hydroponics, plant breeding, hybridization, better management of soil nutrients, and improved weed control. Genetic engineering has yielded crops that have capabilities beyond those of naturally occurring plants, such as higher yields and disease resistance.
Modified seeds germinate faster, and thus can be grown in an extended growing area. However, genetic engineering of plants has proven controversial, particularly in the case of herbicide -resistant plants. Certain aspects of intensive industrial agriculture have been the subject of growing disagreement.
The widening sphere of influence held by large seed and chemical companies, meat packers, and food processors has been a source of concern both within the farming community and for the general public.
There has been increased activity against certain farming practices like factory farms. Another issue is the type of feed given to some animals that can cause bovine spongiform encephalopathy also known as Mad Cow Disease in cattle. There has also been concern because of the disastrous effects that intensive agriculture has on the environment.
In the United Statesfor example, fertilizer has been running off into the Mississippi River for years and has caused a dead spot in the Gulf of Mexicowhere the Mississippi empties. The patent protection given to companies that develop new types of seed using genetic engineering has allowed seed to be licensed to farmers in much the same way that computer software is licensed to users.
This has changed the balance of power in favor of the seed companies, allowing them to dictate previously unheard of terms and conditions. Soil conservation and nutrient management have been important concerns since the s, with the best farmers taking a stewardship role with the land they operate.Food and Economy Food in Daily Life.

The terms "Iran" as the designation for the civilization, and "Iranian" as the name for the inhabitants occupying the large plateau located between the Caspian Sea and the Persian Gulf have been in continual use for more than twenty-five hundred years.

It is suggested that analysis of sedimentary pyrite from the Belingwe sedimentary basin in Zimbabwe may provide evidence for bacterial reduction at this date.
