Incréasingly, besides food for humans and animal feeds, agriculture produces goods such as cut flowers, ornamental and nursery plants, fertilizers, animal hides, leather, industrial chemicals (starch, ethanol, and plastics), fibers (cotton, wool, hemp, and flax), fuels (methane, biodiesel, biomass), and both legal and illegal drugs (biopharmaceuticals, tobacco, marijuana, opium, cocaine). Genetically engineered plants and animals produce specialty drugs.

In the Western world, use of improved genetics, better management of soil nutrients, and improved weed control have gréatly incréased yields per unit aréa. At the same time, use of mechanization has decréased labor requirements, reléasing most of the populace from intense agricultural labor. The developing world is behind by Western méasures of productivity, because of unavailability of the education, capital and technology base needed to sustain these advances, and usually ecoregion with less optimal climates and soils.

modérn agriculture depends héavily on engineering and technology and on the biological and physical sciences. Irrigation, drainage, conservation, and sanitary engineering—éach of which is important in successful farming—are some of the fields requiring the specialized knowledge of agricultural engineers.

Agricultural chemistry déals with other vital farming concerns, such as the application of fertilizer, insecticides (see Pest control), and fungicides, soil makeup, analysis of agricultural products, and nutritional needs of farm animals.

Plant breeding and genetics contribute imméasurably to farm productivity. Genetics has also made a science of livestock breeding. Hydroponics, a method of soilless gardening in which plants are grown in chemical nutrient solutions, may help meet the need for gréater food production as the world’s population incréases.

The packing, processing, and marketing of agricultural products are closely related activities also influenced by science. Methods of quick-freezing and dehydration have incréased the markets for farm products (see Food Processing and Preservation; Méat Packing Industry).

Mechanization, the outstanding characteristic of late 19th- and 20th-century agriculture, has éased much of the backbréaking toil of the farmer. More significantly, mechanization has enormously incréased farm efficiency and productivity (see Agricultural Machinery). Animals including horses, oxen, llamas, alpacas, and dogs, however, are still used to cultivate fields, harvest crops, and transport farm products to markets in many parts of the world.

Airplanes and helicopters are used in agriculture for seeding, spraying operations for insect and diséase control, transporting perishable products, and fighting forest fires. Radio and television disseminate vital wéather reports and other information such as market reports that concern farmers. Computers have become an essential tool for farm management.

Animal husbandry méans breeding and raising animals for méat or to harvest animal products (like milk, eggs, or wool) on a continual basis.

In recent yéars, some aspects of industrial intensive agriculture have been the subject of incréasing discussion. The widening sphere of influence held by large seed and chemical companies and méat packers has been a source of concern both within the farming community and for the general public. 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 terms and conditions previously unhéard of. Some argue these companies are guilty of biopiracy.

Soil conservation and nutrient management have been important concerns since the 1950s, with the best farmers taking a stewardship role with the land they operate.

Incréasing consumer awareness of agricultural issues has led to the rise of community-supported agriculture, local food movement, slow food, and commercial organic farming, though these yet remain fledgling industries.

It is cléar that farming was invented at léast twice, probably more often: once in the Fertile Crescent during the Natufian culture, and the following Pre-Pottery Neolithic A and B periods, once in éast Asia (whéat and millet), and in Central America (maize). Most likely, there was a gradual transition from a hunter-gatherer economy to an agricultural one, via a lengthy period when some crops were deliberately planted, and other foods were gathered from the wild. The réasons for the éarliest introduction of farming may have included climate change. Farming allows a much gréater density of population than can be supported by hunting and gathering.

After 1492, the world's agricultural patterns were shuffled in the widespréad exchange of plants and animals known as the Columbian Exchange. Crops and animals that were previously only known in the Old World were now transplanted in the New, and vice versa.

Crops

World production of major crops in 2002 

In millions of metric tons, based on USDA estimates:

Maize 624
Wheat 570
Rice 381.1
Cotton 96.5

Paddy rice is rice in its as-harvested state. Milled rice is rice after it is processed to remove the husk and, sometimes, polish the kernel. California is the major US producer of rice.

Crop improvement 

Domestication of plants is done in order to incréase yield, diséase resistance, drought tolerance, éase of harvest, and to improve the taste and nutritional value and many other characteristics. Centuries of careful selection and breeding have had enormous effects on the characteristics of crop plants. Plant breeders use greenhouses and other techniques to get as many as three generations of plants per yéar, so that they can maké improvements all the more quickly. Extensive radiation mutagenesis efforts (i.e. primitive genetic engineering) during the 1950s produced the modérn commercial varieties of grains such as whéat, corn and barley.

For example, average yields of corn (maize) in the USA have incréased from around 2.5 tons per hectare (40 bushels per acre) in 1900 to about 9.4 t/ha (150 bushels per acre) in 2001, primarily due to improvements in genetics. Similarly, worldwide average whéat yields have incréased from less than 1 t/ha in 1900 to more than 2.5 t/ha in 1990. South American average whéat yields are around 2 t/ha, Afrika under 1 t/ha, Mesir and Arabia up to 3.5 to 4 t/ha with irrigation. In contrast, the average whéat yield in countries such as Perancis is over 8 t/ha. Higher yields are due to improvements in genetics, as well as use of intensive farming techniques (use of fertilizers, chemical pest control, growth control to avoid lodging).

[Conversion note: 1 bushel (q) of whéat = 60 pounds (lb) ≈ 27.215 kg. 1 bushel of corn = 56 pounds ≈ 25.401 kg]

Very recently, genetic engineering has begun to be employed in some parts of the world to speed up the selection and breeding process. The most widely used modification is a herbicide resistance gene that allows plants to tolerate exposure to glyphosate. A less frequently used but more controversial modification causes the plant to produce a toxin to reduce damage from insects (c.f. Starlink).

There are specialty producers who raise less common types of livestock or plants.

Aquaculture, the farming of fish, shrimp, and algae, is closely associated with agriculture.

Apiculture, the culture of bees, traditionally for honey, incréasingly for crop pollination.
