8. Read the text and say why agriculture is a vital sector of economy.

Agriculture is a human activity in which people use areas of land to produce food, clothing and other necessary materials.

The word ager is a Latin word. It means a field. The word agriculture means the cultivation of fields and growing crops. But this is the old meaning of this word. Now it also means the use of land to breed animals.

Agriculture is the vita1 sector of the economy. Its condition and development largely determine the country’s achievements, the supply of the population with foodstuffs and many industries with raw materials.

At present there are two main branches of agriculture. They are crop growing and livestock breeding.

We do not know when people began to grow crops. It was many thousand years ago. Now crop growing is a highly developed branch of agriculture.

The soil is the basis of agriculture. Enough food for all the people can be grown if there is sufficient good soil for crops to produce high yields. So an increase in the yield of grain and other crops is ensured by a number of factors. First comes the system of agronomical measures. All farms have to introduce better crop rotation systems. Rotation systems naturally differ in various areas and under various conditions. Second goes the technical equipment of farms. Tractors, combines, lorries and other machinery will considerably reduce the time required for agricultural work. Field work has already been mechanized to a very high degree. Power stations provide farms with electricity. Third, an increase in the deliveries of chemical fertilizers and the improvement of their quality.

The enlargement of the material and technical basis of agriculture and its intensification through chemization, the comprehensive mechanization of crop and animal farming and improvement are the key conditions for increasing agricultural production.

Depending upon the soil and climatic zones effective methods should be introduced for the utilization of mineral fertilizers in combination with organic fertilizers along with the liming of acid soils. The production and use of chemical and biological means of plant protection should be increased. But all intensification factors, such as full mechanization, high application of fertilizers and extensive use of herbicides must be used in such a way as not to disturb the biological equilibrium of the soil.

Depending upon the field of application crops can be subdivided into food crops, feed crops, industrial crops and vegetables. Potatoes and other vegetables are major food crops. Vegetables are grown everywhere where the climate is most favourable for these crops.

Industrial crops are also widely cultivated by the farmers. Perhaps the most important industrial crop for textile industry is cotton. Cotton is generally grown on the irrigated lands. Flax is another important crop. Cotton and flax oils are both edible and valuable.

Livestock breeding comprises cattle-breeding, pig-growing, poultry-breeding, etc. One of the principle problems cattle-breeding faces is that of fodder or feeds. To choose the necessary feeds, rich enough in protein and other nutrient substances is not an easy thing. Increasing the production of meat, milk and wool can be achieved by raising productivity and also by increasing the heads of livestock and the amount of poultry.

Agriculture in General

Agriculture is the world's most important industry. It provides us with almost all our food. It also supplies materials for two other basic human needs - clothing and shelter. In addition, agriculture provides materials used in making many industrial products, such as paints and medicines. About half the world's workers are employed in agriculture - far more than in any other industry.

Food is the most important farm product. But farms also provide many other products, from natural fibres to ornamental flowers and trees. Some crops are used only to feed livestock. These forage crops include alfalfa, clover and many grasses. Forage crops are important because they make commercial livestock production possible.

Farms provide almost all the world's food, including some fish and game. Most food products come from crops. The rest come from animals, especially cattle, hogs, poultry, sheep and other livestock.

The world's farmers grow about 85 major food crops. They can be di­vided into eight groups. The main group is cereal grains. Grain is grown on half the world's cropland and supplies much of the nourishment in the hu­man diet. The chief grains are barley, corn, millet, oats, rice, rye, sorghum and wheat.

Various root crops make up the second most important group of food crops. Cereal grains, root crops are grown throughout the world and are a basic food for many people. The leading root crops are potatoes, beets and sweet potatoes.

The six remaining groups of major food crops are: (1) pulses, which consist mainly of beans and peas; (2) fruits and vegetables; (3) oil-bearing crops, such as soybeans and coconuts; (4) sugar-bearing crops, especially sugar cane and sugar beets; (5) nuts; and (6) cocoa beans, coffee, and tea.

Cattle, chickens, goats, hogs, sheep, turkeys and other livestock are the main animals raised for food. Livestock are raised in every country and supply nearly all the world's meat, eggs and milk. Farmers also raise other animals for food. For example, many farmers keep bees for honey. Farmers on fish farms raise freshwater food fish, such as carp and trout, and saltwa­ter shellfish, such as mussels and oysters.

Natural fibres come from a variety of plants and animals raised on farms. Factories use the fibres to make fabrics, yarn and other textile prod­ucts. Cotton and flax together with some tropical plants are the chief plant fibres. Wool, the principal animal fibrs, comes mainly from sheep but also from such animals as goats and members of the camel family. Silk fibres are obtained from the cocoons of silkworms. However the development of synthetic fibres has reduced the demand for natural fibres in some coun­tries.

Many farms provide other raw materials for industry besides fibres. These materials include natural rubber, animal hides which are used to make leather and such vegetable oils as castor oil and linseed oil. These oils are used in a variety of products, from paints to medicines. Many farm­ers grow tobacco. Others grow ornamental flowers, trees and shrubs. A few farmers raise such animals as foxes and minks for their fur.

THE HISTORY OF AGRICULTURE

1. Before you read the passage, talk about these questions.

1 When did farming first begin in your country?

2 What did farmers first grow in your country?

2. Read the text The Development of Agriculture

Agriculture began in the area known as the Fertile Crescent. The area is a hot, dry desert. But it has two of the requirements for farming: good soil and a water supply. Many early farmers used the Nile River as a water supply. The Nile River floods at the same time every year. Farmers planted crops before the floods. This helped their plants to survive in the desert. Later, farmers created irrigation ditches. They moved water from the Nile River to their fields. They could cultivate crops any time of the year and harvest extra food. Producing extra food was important. Later, farmers fed animals with it. These domesticated animals became another important part of

agriculture.

3. Read the textbook passage. Then, mark the following statements as true (T) or false (F).

12. Read and translate the text

From the early ages man tried to cultivate soil using the most elementary method of modifying soil conditions. He broke up the surface and prepared a seed-bed with the most primitive cultivating device, a digging implement - a hoe.

The greatest mechanical advance in the early days of agriculture was the evolution of the plough from the primitive hoe. The use of the plough replaced manual labour by labour of animal power. This is one of the landmarks of agricultural process. It began, thousands years ago, with simple devices for harnessing the power of man himself; then progressed with the construction of implements and machines designed to make use of the greater power of domesticated animals, mostly horses and oxen.

The plough still rests to be the most important tillage tool. It has been changed and improved during the centuries. In the 18th century there was an attempt to improve agricultural implements. New methods and inventions were applied to farming operations. By the 19th century a variety of agricultural implements appeared, which were now called “agricultural machinery”. In agriculture, the use of water-power and then of steam greatly stimulated the invention of machinery, replacing manual labour.

A threshing machine was invented in the second half of seventeen hundreds, and productively used in the 19th century. It was driven by water and wind, sometimes by horse labour, and later by steam.

Later on, in 1860, the internal-combustion engine was invented. It was used to drive stationary machines, as chaff-cutters, root-cutters and corn-mills in the barn. Steam engines, though widely used on the road, suffered the disadvantage in the use on the land. Then the internal-combustion engine was perfected, and agricultural tractors appeared.

But a still newer source of power on the farm is electricity. It was firstly used for lighting. When it became available at low cost, it came into use on the farm.

Agricultural implements are now very numerous. They are subdivided into six groups:

÷ machinery and equipment movers, i.e. engines of all kinds, tractors, etc.;

÷ cultivating machinery: ploughs of all sorts, harrows, rollers, cultivators, etc.;

÷ harvesting machinery, such as mowers, self-binders, threshing machines, combines, elevators, potato-diggers, etc.;

÷ field supplementary equipment: manure and fertilizer distributers, sprinkling installations, sprayers and many others.

÷ stationary (or barn) equipment, including such food-preparing machines as chaff-cutters, grinding-mills, root-cutters, manure-scrappers, distributing belts, etc.;

÷ dairy- machinery, including milking machines, separators, churns, sterilizing machines, etc.

In addition, there is a number of other machines and devices that find intensive use in agricultural production, and sheep-shearing units, rearing chambers, grain conveyers, farm repair shop mechanized equipment, lifting and loading machines being among them.

A) Guess the meaning of the terms and word-combinations underlined in the text, through analysis of their position and the context they appear in;

B) now, look them up in a dictionary;

C) find out the logic behind their use in the given situations;

D) provide as many their synonyms, as you can think of;

From the History of Agriculture

 

1. Study the agricultural terms before reading the text "From The His­tory of Agriculture".

seed [si:d] - семя, зерно

domestication - одомашнивание, приручение

irrigation [lrl'geljn] - орошение

crop rotation - севооборот

selective breeding - селекционное разведение

milking machine - доильный аппарат

pump - насос

feeding trough [trofj - кормушка insect pest - насекомое-вредитель wood ash - древесная зола manure [ma'njua] - навоз

2. Read the text and do the exercises that follow it.

For hundreds of thousands of years, prehistoric people lived by hunting, fishing and gathering wild plants. Then about 8000 B.C. (before Christ - до нашей эры), people took the first steps toward agriculture. Some tribes discovered that plants could be grown from seeds. They also learned that certain animals could be tamed and then raised in captivity. These two discoveries marked the beginning of the domestication of plants and ani­mals. Scholars believe that domestication began in the Middle East and then spread to surrounding areas.

The Romans had developed some farming methods, e.g. systems of crop rotation. The selective breeding of plants and livestock began in Eu­rope during Roman times, too.

Since the 1800s, science and technology have helped make agriculture more and more productive in three main ways. They have provided farm­ers with labor-saving technologies, produced improved plant varieties and breeds of livestock and developed new agricultural chemicals.

Labor-saving technologies. Steam-powered tractors were developed in the mid-1800s, but they were expensive and difficult to operate. The first all-purpose gasoline-powered tractors appeared in the 1920s. They gradually replaced work animals and steam-powered machines on almost all farms. In Japan and several European countries most farms had electric power service by the mid-1930s. Today farmers use electric motors to run milking machines, irrigation pumps, and many other farm machines. Farm­ers also use electric power to operate electronic and automated equipment. This equipment includes devices that fill feeding troughs or collect and grade eggs automatically.

Many farmers use computers to aid in farm operations. Using the In­ternet, farmers may make use of data provided by agricultural colleges or other information centers.

Plant and livestock breeding. During the mid-1800s an Austrian bota­nist and monk named Gregor Mendel discovered the principles of heredity. Mendel thus laid the groundwork for genetics - the science that explains how characteristics are inherited. The development of genetics has made it possible to breed plants and animals scientifically.

Since the early 1900s, plant breeders have developed a great number of hybrid crops that produced unusually high yields. The new varieties were intended mainly to help various poor nations, such as India and Mexico, increase their food supply. This effort proved so successful that it has been called the Green Revolution.

Livestock breeders have introduced many improved lines since the ear­ly 1900s. Nutrition specialists have developed better livestock feeds, and veterinarians have improved methods of health care. All these advances continue to make livestock more and more productive.

Agricultural chemicals. Almost since the beginning of agriculture, farmers have used various substances to enrich the soil and to kill insect pests. For example, they have used wood ash and manure as fertilizers since prehistoric times. Since the beginning of modern chemistry in the late 1700s, scientists have produced many kinds of synthetic chemicals for use in agriculture. These chemicals include fertilizers, insecticides, herbi­cides or weedkillers and chemicals to control plant and animal diseases. All these chemicals have helped increase farm production greatly. However, improper or excessive use of these chemicals can be dangerous and cause damage to the environment. In many countries state laws limit such prac­tices and prohibit the use of chemicals that have been proved harmful.
