Agronomy
Agricultural Land
An area of ground used for farming, including arable land, improved and unimproved
grassland and other pastures.
Arable area
An agricultural land used for the growth of crops which is tilled though not
necessarily each year.
Permanent Grassland (meadow, pasture)
A large area of and covered with grass used for hay (meadows) or for
pasteurizing/grazing (pasture).
Fallow Land
Land that is cultivated or ploughed but it is not used for growing cropsu, usually
uncropped for two or more seasons.
Arable area
An agricultural land used for the growth of crops which is tilled though not
necessarily each year.
Dairy Farming
Farming devoted primarily to keeping cows for their yield of milk, whether for
consumption as milk, or for conversion to butter, cheese or other milk products
Mixed Farming
Agriculture where both crops and livestock are produced on an individual farm.
Livestock Farming
The farming activity based on the rearing of animal livestock for eggs hides, skins,
meat, milk etc. No crops are grown on these farms..
Wasteland
An area that is not used for agriculture, any wild uncultivated land, usually on light
soil that failed to yield.
Hectare (Ha)
0,000m²
2.471 acres
100ha = 1km²
Acres
4,840 square yards
4, 047m²
Area
A unit for measuring area equal to 100m²
1a = 100m² = 0.01ha = 0.0247acres
Yeild
Actual productivity and yield are the same.
Output or production of useful parts of plants expressed in relation to the units of
land.
Seed/Grain/Root etc.
Field Plants (Food crops, industrial crops, horticultural crops)
Plants which are cultivated for the purpose of harvesting seeds, roots, leaves or
other parts that are useful for humans and animals.
Weeds
Plants which harm crops and grow where they are not wanted, often on cultivated
land where they compete with crop plants for space, light, nutrients etc

Natural Habitat
The area in which an organism can live and which affords it relatively favourable
conditions for existence.
A place or a kind of place that provides a particular set of environmental conditions
for the animal inhabiting it
Environment
The complete range of external conditions, physical, chemical and biological in which
an organism lives.
The sum of all the external conditions of the surrounding in which an organism lives.
Social/Cultural/Exonomic/Soil/Climate/Food supply etc
Photoperiodism
The response of an organism to periodic, often rhythmic, changes in either intensity
of light, or more usually the length of the day.
A biological response to changes in the ratio of light and dark in a 24 hour cycle.
Growing Season
The season of rapid growth, the part of the year when plant growth is active on
account of favourable temperature, availability of moisture and sufficient hours of
daylight. The duration of the season usually decreases with increasing distance from
the equator.
Transpiration
The loss of water vapour by plants to the atmosphere. Normally from leaves, through
pores who's primary function is gas exchange. 20% of water taken in by roots is
transpired.
Evapotranspiration
The total return of water from the land to the atmosphere.
Combination of:
Evaporation from the soil surface.
Transpiration from plants.
Photosynthesis
The chemical process by which green plants and other phototrophs synthesize
organic compounds from carbon dioxide and water in the presence of sunlight.
Soil Moisture
The moisture in the pore spaces of soil, important for plant growth. Moisture held in
the capillary soil pores.
Wilting Point
The point at which a plant has to supply water from its own tissue for transpiration
when soil moisture is exhausted.
The point below which the amount of water stored in the soil cannot be absorbed by
plants quickly enough to meet their needs causing wilt.
Field Capacity
Amount of soil moisture or water content held in the soil after excess water has
drained away and the rate of downward movement has decreased. This usually
takes place 2-3 days after rain or irrigation in pervious soils of uniform structure and
texture.
Drainage
The naturally occurring channelled flow formed by streams and rivers and removes
water from the land surface.
Open drainage channels that permit excess water to flow into rivers that carry it out
to sea.
