Definitions & Concepts: Agriculture, Forestry and Fishing
 
Agricultural holder: is a natural or legal person who individually or jointly exercises management control over the agricultural holding. The holder has technical and economic responsibility for the holding as well as direct role in its profit and loss.

Annual crops: mostly herbaceous plants whose stems are destroyed by harvesting and whose subterranean organs (as root, bulb, etc.) remain, in some cases, in the earth, like: wheat, sugar beet, vegetables and saffron.

Arable land: land allocated to farming, either under cultivation or left fallow.

Area under cultivation: area allocated to crop production in the year of the survey implementation that has been cultivated in the same year or the year before.

Artificial windbreak: rows of artificial obstacles (like fence, wall, dead branches, etc.) constructed across the usual wind direction to break the force of the wind and lower its speed, causing the sand and other materials carried by the wind to be deposited behind in an order of size.

Breeder chickens: fertile eggs of this breed are used to produce chickens. Breeder chickens of broiler and layer breeds are reared to produce chickens of the same breed.

Broiler chicken: hen or rooster reared for its meat.

Capital properties: all machinery, equipment and tools usually used in manufacturing activities or for rendering services with an economic life of more than one year. Machinery and   power equipment, durable tools and implements, office equipment, vehicles and buildings, are examples of such properties.

Compensation of wage/ salary earner:  wage, salary and other payments (money, goods, etc.) received by wage/ salary earner.

Cooperative: refers to company composed of at least 7 natural persons as members who finance either whole or 51 percent of the capital. It is registered according to regulations in the law of cooperative sector. It should be noted that before determining the minimum number of the cooperatives' members under the mentioned law, some of the cooperatives were established with less than 7 members.

Crop year: begins on Mehr 1st and lasts until the end of Shahrivar in the next year.

Delineation:  exact estimation of the area and   admitted limits of each husbandry in a range for one or more rangemen.

Fallow: the part of arable land, irrigated or rainfed, which is included in crop alternation, but has not been cultivated in the given agricultural year and from which no crop would be harvested.

Farming: holdings with at least 400 square metres of arable land at the time of enumeration

Greenhouse production: holdings having activity in this field in every size during the intended crop year.

Horticulture: holdings with at least 200 square metres of orchards and nurseries at the time of enumeration.

Investment (value of changes in capital properties): changes in the value of capital properties (value of purchase or   obtaining of capital properties plus cost of major repairs minus sale or transfer value of these properties) during a definite period of time.

Irrigated arable land: is a cultivated land in which the crops growing are irrigated.

Layer chicken: these chickens, called pullet when three months old, are reared to produce edible eggs.

Living windbreak: a line of trees, shrubs or other vegetation planted across the usual wind direction to break the force of the wind and lower its speed, causing the sand and other materials carried by the wind to be deposited behind in an order of size.

Log: a portion of the trunk of a fallen tree, almost cylindrical, used to produce types of wood or veneer.

Modern cattle farm: an agricultural production unit where cattle are raised according to modern procedures and methods with respect to the characteristics of the place, rearing, feeding, and health.

Modern irrigation and drainage network: comprises installations for draining and supplying water to arable lands with an area about 60 to 200 hectares. The network, equipped with systems for water control, distribution and measurement, procures water in normal hydrologic conditions with at least 80% guarantee.

Mulching: to create vegetation (mulching) over the soil to prevent it from moving, losing temperature or drying out.

Other payments (money, goods, etc.): includes bonus, overtime, food and clothing allowance, commuting allowance, child allowance, spouse allowance, mission allowance, unfavourable climate allowance, employer’s share of social security premium, food stuff, bus ticket, etc.

Perennial crops: are plants with wooden stems or trunks, all or some parts of which will remain in the earth to crop the next year. Different types of fruit trees like citrus and peach trees, vines and tea plants as well as fruitless trees like poplar are considered as perennial crops.

Pitprop: rounded piece of wood, almost two metres long, with a median diametre of 6 to 20 centimetres and used in mines.

Pole: wood from the trunk of a tree the chest-high diametre of which is between 8 and 30 centimetres.

Preservation: selection and declaration of the areas of regions with high erosion or sensitive to erosion.

Production of   one-day-old chickens:  through the processes of this activity, depending on the case, fertile eggs of layer and broiler chickens turn into one-day-old chickens of ancestor and breeder hens, roosters, layer and broiler breeds.

Production: the quantity of the products obtained through the production process during a definite period of time in the agricultural production unit which is ready for sale and consumption. In the statistical surveys of the SCI, the share of agricultural crops produced free of charge, or the compensation of which is paid in kind or is consumed by the same agricultural production unit is included with the production.

Pulpwood:  wastes of   articles   of    wood    in different sizes and lengths.

Rainfed arable land: cultivated lands that are not   irrigated    but    left   to be watered through

Raising of large livestock: holdings raising large livestock (cows, buffaloes and camels) which have had at least one large livestock during the last 365(1) days.

Raising of large livestock: holdings raising large livestock (cows, buffaloes and camels) which have had at least one large livestock during the last 365(1) days.

Raising of silkworm and honeybees: holdings having activity in this field in every size during the last 365 (1) days.

Raising of small livestock: holdings raising small livestock (sheep and goats) which have had at least two small livestock during the last 365(1) days.

Range: a land, be it a mountain, mountainside, or a plain, which is covered with herbaceous forage crops in grazing season and already grazed, is commonly known as range. Fallows, even though covered with herbaceous forage crops, are not included in this category.

Sawn wood: articles of wood in specific sizes (length, width and height).

Shallow wells: wells dug in mountainsides to supply livestock drinking water. Water of these wells rises to the surface without pumping like artesian wells or springs.

Shell-less eggs: eggs lacking the outer hard shell.

Timber: round wood 1.5 to 2.0 metres in length and 20-40 centimetres in diametre that cannot be turned into sawn wood.

Wage and salary: all payments in kind or in cash to the wage/salary earners by the establishments.

Water trough: shallow wells supplying livestock drinking water only.

Watershed areas: lands lying in the river basin leading running water resulted from precipitation to the lake.

Watershed management: activities performed for the reclamation and restoration of watershed areas.

Workers: include all people working inside or outside of the establishment, full-time or part-time, with or without wage and salary (owners, active partners and unpaid family workers).
