The uppermost and the darkest layer of the soil that contains most of the organic matter, living organisms and plant roots.
The upper part of the soil, which is the most favorable material for plant growth. It is ordinarily rich in organic matter and is used to topdress.roadbanks, lawns, and land affected by mining.
The top layer of soil containing valuable nutrients.
The uppermost part of the soil ordinarily moved in tillage, or its equivalent in uncultivated soils. Topsoil ranges from 8-10 cm to 20-25 cm in depth. It is frequently designated as the plow layer.
The top soil horizons, which are typically dark and
upper, fertile layers of soil.
the upper layer, "A" horizon of soil in which plants grow; usually richer in plant food than the subsoil; the plowed layer
Terre arable Schwarzerde, f Capa superior del suelo Dark in color and crumbly, this is the better layer of soil.
That part of the soil profile, typically the A1 horizon, containing material which is usually more fertile and better structured than underlying layers. When the A2 horizon also meets these criteria, it may be included. Topsoil is the most important part of the soil with respect to growth of crops and pastures and its loss or degradation represents the most serious aspect of soil erosion. Its retention is particularly important in the revegetation of exposed batters or earthworks.
is a part of the soil profile, typically the first soil layer (called the A1 horizon) below the ground surface that is darker in colour, more fertile and better structured than underlying layers
The surface portion of the soil, usually the average plough depth, which may also include the sub-surface soil that contains organic matter.
Surface soil usually containing organic matter.
The first true layer of soil; layer in which organic material is mixed with mineral particles; thickness ranges from a meter or more under virgin prairie to zero in some deserts.
The usually more fertile top layer of soil - see subsoil.
surface soil usually including the organic layer in which plants have most of their roots and that the farmer turns over in plowing Minnesota: Modern Farming
the layer of soil on the surface
The uppermost layer of soil. Presumably fertile and cultivated by farmers.
The layer of soil moved in agricultural cultivation.
The upper part of the soil, where most of the organic matter is found.
rich, upper layer of soil.
the uppermost layer of soil, rich in organic matter incorporated from the decay of plants and the activities of micro-organisms, intermixed with mineral matter derived from the underlying subsoil.
The top eight inches of soil
The surface soil, normally containing organic matter.
The uppermost layer of the soil, characterized by a high organic content; the organic layer of the soil.
the surface layer of soil that is formed by the decomposition of organic matter at the surface.
The surface plow layer of a soil; also called surface soil. The original or present dark-colored upper solid that ranges from a mere fraction of an inch to two or three feet thick. The original or present "A" horizon varies widely among different soil types. Applied to soils in the field, the term has no precise meaning unless defined as to its depth or the productivity in relation to a specific kind of soil.
The layer of soil moved in agriculturalcultivation.
layer of soil rnoved in cultivation. The A-horizon Presumably fertile soil material used to topdress roadbanks, gardens. and lawns
surface layer of mature soil, containing large amounts of organic material
the top layer of soil; topsoil can grow better crops partly because it has more organic matter (humus), allowing it to hold more water than lower soil layers
A part of the soil profile, typically the A1 horizon, containing material which is usually darker, more fertile and better structured than the underlying layers.
The surface soil manipulated by cultivation. Often called the plough layer approximated as 15cm deep.
Surface layer of soil with higher organic content, A horizon.
the surface layer of soil containing partly decomposed organic debris, which is usually high in nutrients, contains many seeds, and is rich in mycorrhizae.
The top layer of native soil. This term may also apply to good quality soil sold at nurseries and garden centers.
The uppermost layer of soil that is the site for plant's root growth and contains the most organic matter.
The top, most fertile layer of soil
A general term applied to the top natural layer of soil.
uppermost layer of soil, usually darker and richer than the subsoil.
The uppermost part of the soil, ranging in depth from three to 10 inches, and generally containing higher amounts of organic matter and plant nutrients than the soil below. Topsoil is often functionally defined as the soil layer moved in primary tillage or the equivalent depth in uncultivated soils. This definition is rather arbitrary in deep, untilled soils with no clear indication of where topsoil ends and the next soil layer begins.
surface soil at and including the average plow depth, soil which is used as a planting or growing medium.
the upper part of the soil; surface soil, as opposed to subsoil; loam or other earth from or in this part of the soil, usually consisting of sand, clay, and decayed organic matter. [AHDOS
Topsoil is the uppermost layer of soil, usually the top 15-20 cm. It has the highest concentration of organic matter and microorganisms, and is where most of the Earth's biological soil activity occurs. Plants generally concentrate their roots in, and obtain most of their nutrients from this layer.
