What is agro-ecological zone?

An Agro-ecological Zone is a land resource mapping unit, defined in terms of climate, landform and soils, and/or land cover, and having a specific range of potentials and constraints for land use. An Agro-ecological Cell (AEC) is defined by a unique combination of landform, soil and climatic characterist.

What does ecological zone mean?

An ecological zone is a landscape unit that unites certain interrelated animal and plant communities (biocenosis) with a particular social formation and environmental conditions as part of an integrated system. The definition of an ecological [Page 844]zone relies on flexible criteria.

What is the importance of agro-ecological zones?

Agro-ecological zoning (AEZ) is one of the most important approaches for agricultural developmental planning because survival and failure of particular land use or farming system in a given region heavily relies on careful assessment of agro-climatic resources.

How many ecological zones are there?

ECOZONES OF THE WORLD At least nine ecological zones are recognized (Schultz 2005). They occur in bands, which may be fragmented owing to the irregular configuration of the continents and oceans, from the poles to the equator.

What is an ecological zone?

Why agro-ecological zone is important?

Soils form the second element in defining and differentiating agroecological zones as soil conditions determine important properties for plant growth, moisture supply, root aeration and nutrient supply. The third factor is land level in relation to flooding.

What are the ecological zones?

An ecotope is a pure land unit of the lowest rank that is associated with a uniform or homogeneous landscape.

What are the different ecological zones?

The five major Domains were Tropical, Subtropical, Temperate, Boreal and Polar. These were considered to divide the globe into five broad but ecologically valid units for global forest reporting, and the subzones provide more detailed categories where required within a broad zone.

What are the physical features of the Balochistan Plateau?

The Balochistan plateau The vast tableland of Balochistan contains a great variety of physical features. In the northeast a basin centred on the towns of Zhob and Loralai forms a trellis-patterned lobe that is surrounded on all sides by mountain ranges.

Which is the most important range in Balochistan?

The easternmost Kirthar Range is backed by the Pab Range in the west. Other important ranges of southern Balochistan are the Central Makran Range and the Makran Coast Range, whose steep face to the south divides the coastal plain from the rest of the plateau.

Is the Quetta Basin a mountain or a plateau?

The small Quetta basin is surrounded on all sides by mountains. The whole area appears to form a node of high ranges. West of the Ras Koh Range, the general landform of northwestern Balochistan is a series of low-lying plateaus divided by hills.

Which is more fertile Potwar Plateau or Sialkot plateau?

The Sialkot region is a narrow submontane area in the northeast. Unlike the Potwar Plateau, it is a rich agricultural region. Precipitation varies from 25 to 35 inches (650 to 900 mm) per year, and the water table is high, facilitating well (and tube-well) irrigation; the soil is heavy and highly fertile.
