The practice of agriculture product manufacturersagriculture is also known as “farming”, while scientists, inventors and others devoted to improving farming methods and implements are also said to be engaged in agriculture. Subsistence farming, who farms a small area with limited resource inputs, and produces only enough food to meet the needs of his/her family.
At the other end is commercial intensive agriculture, including industrial agriculture.
Such farming involves large fields and/or numbers of animals, large resource inputs (pesticides, fertilizers, etc.), and a high level of mechanization.
These operations generally attempt to maximize financial income from grain, produce, or livestock. Modern agriculture extends well beyond the traditional production of food for humans and animal feeds.
Other agricultural production goods include timber, fertilizers, animal hides, leather, industrial chemicals (starch, sugar, alcohols and resins), fibers (cotton, wool, hemp, silk and flax), fuels (methane from biomass, ethanol, biodiesel), cut flowers, ornamental and nursery plants, tropical fish and birds for the pet trade, and both legal and illegal drugs (biopharmaceuticals, tobacco, marijuana, opium, cocaine). The 20th Century saw massive changes in agricultural practice, particularly in agricultural chemistry.
Agricultural chemistry includes the application of chemical fertilizer, chemical 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. Other recent changes in agriculture include hydroponics, plant breeding, hybridization, gene manipulation, better management of soil nutrients, and improved weed control.
Genetic engineering has yielded crops which have capabilities beyond those of naturally occuring plants, such as higher yields and disease resistance.
Modified seeds germinate faster, and thus can be grown in an extended growing area.agriculture product suppliers
Genetic engineering of plants has proven controversial, particularly in the case of herbicide-resistant plants. As of 2006, an estimated 36 percent of the world’s workers are employed in agriculture (down from 42% in 1996), making it by far the most common occupation.
However, the relative significance of farming has dropped steadily since the beginning of industrialization, and in 2006 for the first time in history the services sector overtook agriculture as the economic sector employing the most people worldwide.
Also, agricultural production accounts for less than five percent of the gross world product (an aggregate of all gross domestic products).

Nowadays, naturally disasters occur frequently all around the world, inevitably affection various aspects of social life. These natural disasters, such as earthquakes, hurricanes, floods, fires, volcanoes, tornadoes have devastation effects, especially exerting strong influence on agriculture. They challenge agricultural production to a great extent because agricultural production is highly dependent on weather, climate and water availability. It can be adversely affected by natural events and natural disasters.
Agricultural impacts from natural disasters generally include: contamination of water, loss of harvest or livestock, increased susceptibility to diseases, and destruction of irrigation systems and other agricultural infrastructure. Such impacts can have long lasting effects on agricultural production including crops, forest growth and arable lands, which require time to grow and thrive. The following are some specific examples of natural disasters and their influences on agriculture.
Floods are among the greatest natural disasters known to mankind. Impacts of floods on agriculture cannot be ignored. Floods cause loss of soil nutrients, soil erosion, permanent damage to perennial crops and livestock, greater susceptibility to diseases and insects etc. hot weather and extreme heat can worsen ozone levels and air quality. Excessive heat and prolonged drought conditions can affect agriculture by creating work safety issues for farm field workers, severely damaging crops and reducing availability of water and food supply for livestock. Wildfires can spread quickly and devastate thousands of acres of agricultural land. This devastation may lead to large losses in crops, forests, livestock and agricultural infrastructure. Earthquake is another common disaster which strikes the earthquake without much warning and causes dramatic changes to the landscape of an area. It also has devastating impacts on agricultural production and environment, including loss of harvest or livestock and destruction of irrigation systems and other farming properties. Also some other forms of natural disasters also may have great negative influences on agriculture. In fact, the frequency and seriousness of natural disasters have become the shared research issue for scientists all over the world and some experts suggest that the scientists should combine their efforts together to fight against the shared enemy.
From the above, it can be easily seen that as the agriculture depends much on nature, thus the harvest is greatly determined by the nature. In addition to investing in the agriculture facility construction, some other methods should also be adopted such as to develop crops with stronger life, to increase the reliability of the weather forecast etc.
