"... Teaching - it's one thing to throw ideas in the mailbox of the human subconscious. You always know where they are sent, but never know when they will be received and in what form ... "A. Lovell
natural conditions of the area (topography, rasandik engineering amount of light, rasandik engineering heat, water, soil);
level of industrialization (the existence of enterprises for processing agricultural products), ethnic and religious characteristics of the country (such as East Asia's leading crop is rice; Muslims eaten pork).
There are two types of agriculture rasandik engineering - trade (intensive) and consumer (extensive). For typical commercial type of intensive agriculture plodozminnoyu crop rotation and intensive breeding of forage, horticulture, gardening. For the second type is characteristic of plow and hoe agriculture, grazing, semi-nomadic and nomadic herding, primitive gathering, hunting, fishing. In developed countries, prevailing commodity agriculture in developing countries - commodity and consumer.
Agriculture consists of two main areas: crop production and animal husbandry. Value of crops and livestock rasandik engineering in countries of different regions of the world differently. In the developed countries of Europe and America is dominated by highly productive rasandik engineering livestock, and in developing countries, - Plant.
Crop. There are two main types of crop - nepolyvne and irrigated. Other most common rasandik engineering in the tropics, subtropics and dry subekvatorialnyh latitudes, the largest area of irrigated land - in China, India, Mexico, Pakistan. Basis crop - grain farming. Cereals occupy almost of the treated area, they are a major source of vegetable rasandik engineering protein in the diet. Every year about to about 2 billion tons of grain per year. Almost 4/5 of world production falls into three main "bread of mankind" - wheat, rice and corn.
The main areas of wheat crop is moderate and subtropical latitudes of Eurasia, North and South America, and Australia. The main producers of wheat in the world - China, India, USA, France, Russia, Canada, Australia.
The major crops - cotton - grown mainly in developing countries. The largest producers - China, USA, India, Pakistan, Egypt, Uzbekistan, Thailand and others. More than half the sugar derived from sugar cane (Cuba Brazil, Mexico, Jamaica, etc.), rasandik engineering the rest - from sugar beet (Ukraine, France, Germany, rasandik engineering Russia, etc.).
Animal developed in all regions of the globe. rasandik engineering It is quite varied in composition, direction, intensity and level of performance. In animal isolated cattle, pigs, sheep, poultry, horse breeding, beekeeping, etc.. Leading industry is livestock herding. Among the most common livestock industries including farming, which has been breeding cattle. More than half of the cattle rasandik engineering among the countries of the developing world. Most livestock in India, Brazil, China, the U.S., Argentina. In economically developed countries in Europe, rasandik engineering North America, forest and steppe zones bred cattle meat and milk and dairy areas. The largest producers of milk - Europe. In countries with arid and dry climates, such as India, Pakistan, Argentina, Australia - developed extensive breeding beef. In the semi and deserts, savannas, and in densely populated rural areas of developing countries, dominated by livestock meat and meat-fold direction.
Pig common rasandik engineering everywhere except rasandik engineering in Muslim countries. A significant number of pigs in China (almost 50%), Europe (Germany, France, Italy, UK, Russia, Ukraine, Poland), and 10% - in the United States.
Sheep common almost everywhere. But most of the sheep vypasayetsya in semiarid and arid areas of the world. The largest producers of wool and mutton - Australia, New Zealand, South Africa, Argentina, India. Sheep are also developed in the United Kingdom, Spain, rasandik engineering Turkey, China, USA and others. In recent decades, the livestock industry has become a promising specialized intensive poultry meat and egg trends. It is concentrated in countries with a certain tradition of consumption of these products in areas with strong forage base.
As with all sectors of the world economy, agriculture has undergone significant changes in the age of the STR. In the twentieth century. started technical re-equipment of agricultural production. In the 70 - 80 years of the twentieth century. was the introduction of improved engines, a radically new equipment, new soil technology, chemicals, selection and breeding, Hydrotechnical construction, rasandik engineering etc., and such conversion rasandik engineering covered not only developed countries, but some developing countries (India, Mexico, Argentina and others. ).
