farm management, making and implementing of the decisions involved in organizing and operating a farm for maximum production and profit. Farm management draws on agricultural economics for information on prices, markets, agricultural policy, and economic institutions such as leasing and credit. It also draws on plant and animal sciences for information on soils, seed, and fertilizer, on control of weeds, insects, and disease, and on rations and breeding; on agricultural engineering for information on farm buildings, machinery, irrigation, crop drying, drainage, and erosion control systems; and on psychology and sociology for information on human behaviour. In making his decisions, a farm manager thus integrates information from the biological, physical, and social sciences.

Because farms differ widely, the significant concern in farm management is the specific individual farm; the plan most satisfactory for one farm may be most unsatisfactory for another. Farm management problems range from those of the small, near-subsistence and family-operated farms to those of large-scale commercial farms where trained managers use the latest technological advances, and from farms administered by single proprietors to farms managed by the state.

In Southeast Asia the manager of the typical small farm with ample labour, limited capital, and only four to eight acres (1.6–3.2 hectares) of land, often fragmented and dispersed, faces an acute capital–land management problem. Use of early maturing crop varieties; efficient scheduling of the sequence of land preparation, planting, and harvesting; use of seedbeds and transplanting operations for intensive land use through multiple cropping; efficient use of irrigation and commercial fertilizer; and selection of chemicals to control insects, diseases, and weeds—all of these are possible measures for increasing production and income from each unit of land.

In western Europe the typical family farmer has less land than is economical with modern machinery, equipment, and levels of education and training, and so must select from the products of an emerging stream of technology the elements that promise improved crop and livestock yields at low cost; adjust his choice of products as relative prices and costs change; and acquire more land as farm labour is attracted by nonfarm employment opportunities and farm numbers decline.

On a typical 400-acre (160-hectare) corn-belt farm in the United States with a labour force equivalent to two full-time men, physical conditions and available technologies allow a wide range of options in farming systems. To reach a satisfactory income requires operating on an increasing scale of output and increasing specialization. Corn and soybean cash-crop farming systems have increased in number along with corn-hog-fattening farms and corn-beef-fattening farms. Thus, the choice of a farming system, the degree of specialization to be chosen, the size of operation, and the method of financing are top concerns of management.

For a typical crop-livestock farm in São Paulo’s Paraíba Valley, Brazil, large-scale use of hired labour creates a substantial management problem. With 30 to 40 workers per establishment, procuring and managing the labour—keeping abreast of demand and supply conditions for hired labour, working out contractual arrangements (wage rates and other incentives), deciding how to combine labour with other inputs, and supervising the work force—are of critical importance.

A rancher with thousands of acres, whether in the pampas of Argentina, the plains of Australia, or the prairies of the United States, is concerned about the rate of increase of the herd through births and purchases and herd composition—cows, calves, yearlings, steers, heifers. Risks from drought, winter storms, and price changes can be high. Weather, prospective yields, and the price outlook are the constant concern of competent and alert farm managers.

On a collective farm in the Soviet Union with 30,000 acres (12,000 hectares) and 400 workers, major management decisions are made by party–state representatives; the collective-farm chairman responds largely to their directives, though the farm manager is being given greater autonomy. Major management concerns are determining optimal size of the collective, improving labour incentives, increasing crop and livestock yields, and reducing unit costs—with emphasis on levels of fertilizer, on pesticide and herbicide use, and on conservation of soil and water in crop production.

Thus, the character of the world’s agriculture is shaped as millions of farmers manage the resources under their control in ways to obtain as much satisfaction as possible from their decisions and actions, which are made in a large variety of settings in regard to human, capital, and land resource combinations; technological possibilities; and social and political arrangements. Future agricultural progress depends on improving the quality of management and the environment in which farmers make decisions and on helping them adjust their decisions to the changing environment. In the low-income agricultures of the world in the 1980s, expanded research, improved input supplies and transport facilities, enlarged market opportunities, and an otherwise encouraging environment promise to open up a much wider area for managerial choice and decision making
