TALKS ABOUT AGRICULTURE (PART 2)

AGRICULTURE is is very important sector in the world to supply food for inhabitants, Agriculture the art and science of cultivating the soil, growing crops and raising livestock. It includes the preparation of plant and animal products for people to use and their distribution to markets. Agriculture provides most of the world’s food and fabrics. Cotton, wool, palm oil, fish, meat and many others are all agricultural products. Agriculture also provides wood for construction and paper products also produce more food chain and industrial product. These products, as well as the agricultural methods used, may vary from one part of the world to another. For me the start of agriculture over centuries with the growth of agriculture contributed to the rise of civilizations. This blog in "Anim Agriculture Technology'' we share about the agriculture and their important.

A period of important agricultural development began in the early 1700s in Europe for Great Britain and the Low Countries (Belgium, Luxembourg, and the Netherlands, which lie below sea level). New agricultural inventions dramatically increased food production in Europe and European colonies, particularly the United States and Canada. One of the most important of these developments was an improved horse-drawn seed drill invented by Jethro Tull in England. Until that time, farmers sowed seeds by hand. Tull’s drill made rows of holes for the seeds. By the end of the 18th century, seed drilling was widely practiced in Europe. Many machines were developed in the United States. The cotton gin, invented by Eli Whitney in 1794, reduced the time needed to separate cotton fiber from seed. In the 1830s, Cyrus McCormick’s mechanical reaper helped modernize the grain-cutting process. At about the same time, John and Hiram Pitts introduced a horse-powered thresher that shortened the process of separating grain and seed from chaff and straw. John Deere’s steel plow, introduced in 1837, made it possible to work the tough prairie soil with much less horsepower. Along with new machines, there were several important advances in farming methods. By selectively breeding animals (breeding those with desirable traits), farmers increased the size and productivity of their livestock.

Cultures have been breeding animals for centuries evidence suggests Mongolian nomads were selectively breeding horses in the Bronze Age. Europeans began to practice selective breeding on a large scale beginning in the 18th century. An early example of this is the Leicester sheep, an animal selectively bred in England for its quality meat and long, coarse wool. Plants could also be selectively bred for certain qualities. In 1866, Gregor Mendel’s studies in heredity were published in Austria. In experiments with pea plants, Mendel learned how traits were passed from one generation to the next. His work paved the way for improving crops through genetics. New crop rotation methods also evolved during this time. Many of these were adopted over the next century or so throughout Europe. For example, the Norfolk four-field system, developed in England, proved quite successful. It involved the yearly rotation of several crops, including wheat, turnips, barley, clover, and ryegrass. This added nutrients to the soil, enabling farmers to grow enough to sell some of their harvest without having to leave any land unplanted. Most of the world was not affected by these developments, however. Farmers in Asia, Australia, Africa, and South America continued to use old ways of agriculture. Agricultural Science as in the early 1900s in which an average farmer in the U.S. produced enough food to feed a family of five. Many of today’s farmers can feed that family and a hundred other people. How did this great leap in productivity come about? It happened largely because of scientific advances and the development of new sources of power. By the late 1950s, most farmers in developed countries were using both gasoline and electricity to power machinery. Tractors had replaced draft animals and steam-powered machinery. Farmers were using machines in almost every stage of cultivation and livestock management. Electricity first became a power source on farms in Japan and Germany in the early 1900s. By 1960, most farms in the U.S. and other developed countries were electrified. Electricity lit farm buildings and powered such machinery as water pumps, milking machines, and feeding equipment. Today, electricity controls entire environments in livestock barns and poultry houses.

Traditionally, farmers have used a variety of methods to protect their crops from pests and diseases and to irrigate. They have put herb-based poisons on crops, handpicked insects off plants, bred strong varieties of crops, and rotated crops to control insects. Now, almost all farmers, especially in developed countries, rely on chemicals to control pests. The definition of “pest” ranges from insects to animals such as rabbits and mice, as well as weeds and disease-causing organisms bacteria, viruses, and fungi. With the use of chemicals more crop losses and prices have declined dramatically. 
For thousands of years, farmers relied on natural fertilizer materials such as manure, wood ash, ground bones, fish or fish parts, and bird and bat waste called guano to replenish or increase nutrients in the soil. In the early 1800s, scientists discovered which elements were most essential to plant growth: nitrogen, phosphorus, and potassium. Later, fertilizer containing these elements was manufactured in the U.S. and in Europe. Now, many farmers use chemical fertilizers with nitrates and phosphates because they greatly increase crop yields.  However, pesticides and fertilizers have come with another set of problems. The heavy reliance on chemicals has disturbed the environment, often destroying helpful species of animals along with harmful ones. Chemical use may also pose a health hazard to people, especially through contaminated water supplies. Agricultural scientists are looking for safer chemicals to use as fertilizers and pesticides. Some farmers use natural controls and rely less on chemicals. Continue to read part 3 of the agriculture article. Thanks...
