Biological control agents such as these include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biological control agents of weeds include seed predators, herbivores, and plant pathogens.
Controlled-environment agriculture (CEA) -- which includes indoor agriculture (IA) and vertical farming—is a technology-based approach toward food production. The aim of CEA is to provide protection from the outdoor elements and maintain optimal growing conditions throughout the development of the crop.
In 1632, Wouter van Twiller took control of Bowery No. 1 when he became Director of New Netherland. During his stewardship over the farm he oversaw many improvements, including adding a house, a brewery, and barns. The largely self-sufficient farm's primary product is thought to have been the staple wheat, rather than a cash crop like tobacco.
The percentage of Americans who live on a farm diminished from nearly 25% during the Great Depression to about 2% now, [8] and only 0.1% of the United States population works full-time on a farm. As the agribusiness lobby grows to near $60 million per year, [ 9 ] the interests of agricultural corporations remain highly represented.

A farm (also called an agricultural holding) is an area of land that is devoted primarily to agricultural processes with the primary objective of producing food and other crops; it is the basic facility in food production.

A four-ox-team plough, circa 1330. The ploughman is using a mouldboard plough to cut through the heavy soils. A team could plough about one acre (0.4 ha) per day. The typical planting scheme in a three-field system was that barley, oats, or legumes would be planted in one field in spring, wheat or rye in the second field in the fall and the third field would be left fallow.
In agriculture, disease management is the practice of minimizing disease in crops to increase quantity or quality of harvest yield.. Organisms that cause infectious disease in crops include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants.
