Alkali soil (gcide) | Alkali soil \Alkali soil\
Any one of various soils found in arid and semiarid regions,

these salts is mainly soda with a smaller amount of potash,
and usually a little lime and magnesia. Two main classes of
alkali are commonly distinguished: black alkali, which may
be any alkaline carbonate, but which practically consists of
sodium carbonate (sal soda), which is highly corrosive and
destructive to vegetation; and white alkali, characterized
by the presence of sodium sulphate (Glauber's salt), which is
less injurious to vegetation. Black alkali is so called
because water containing it dissolves humus, forming a
dark-colored solution which, when it collects in puddles and
evaporates, produces characteristic black spots.

black alkali (gcide) | Alkali soil \Alkali soil\
Any one of various soils found in arid and semiarid regions,
containing an unusual amount of soluble mineral salts which
effloresce in the form of a powder or crust (usually white)
in dry weather following rains or irrigation. The basis of
these salts is mainly soda with a smaller amount of potash,
and usually a little lime and magnesia. Two main classes of
alkali are commonly distinguished: black alkali, which may
be any alkaline carbonate, but which practically consists of
sodium carbonate (sal soda), which is highly corrosive and
destructive to vegetation; and white alkali, characterized
by the presence of sodium sulphate (Glauber's salt), which is
less injurious to vegetation. Black alkali is so called
because water containing it dissolves humus, forming a
dark-colored solution which, when it collects in puddles and
evaporates, produces characteristic black spots.

[1913 Webster]
Vegetable kingdom (Nat. Hist.), that primary division of
living things which includes all plants. The classes of
the vegetable kingdom have been grouped differently by
various botanists. The following is one of the best of the
many arrangements of the principal subdivisions.
[1913 Webster] I. Phaenogamia (called also
Phanerogamia). Plants having distinct flowers and true
seeds. [ 1. Dicotyledons (called also Exogens). --
Seeds with two or more cotyledons. Stems with the pith,
woody fiber, and bark concentrically arranged. Divided
into two subclasses: Angiosperms, having the woody fiber
interspersed with dotted or annular ducts, and the seeds
contained in a true ovary; Gymnosperms, having few or no
ducts in the woody fiber, and the seeds naked. 2.
Monocotyledons (called also Endogens). -- Seeds with
single cotyledon. Stems with slender bundles of woody
fiber not concentrically arranged, and with no true bark.]
[1913 Webster] II. Cryptogamia. Plants without true
flowers, and reproduced by minute spores of various kinds,
or by simple cell division. [ 1. Acrogens. -- Plants
usually with distinct stems and leaves, existing in two
alternate conditions, one of which is nonsexual and
sporophoric, the other sexual and oophoric. Divided into
Vascular Acrogens, or Pteridophyta, having the
sporophoric plant conspicuous and consisting partly of
vascular tissue, as in Ferns, Lycopods, and Equiseta, and
Cellular Acrogens, or Bryophyta, having the sexual
plant most conspicuous, but destitute of vascular tissue,
as in Mosses and Scale Mosses. 2. Thallogens. -- Plants
without distinct stem and leaves, consisting of a simple
or branched mass of cellular tissue, or reduced to a
single cell. Reproduction effected variously. Divided into
Algae, which contain chlorophyll or its equivalent, and
which live upon air and water, and Fungi, which contain
no chlorophyll, and live on organic matter. (Lichens are
now believed to be fungi parasitic on included algae.]
[1913 Webster]
Note: Many botanists divide the Phaenogamia primarily into
Gymnosperms and Angiosperms, and the latter into
Dicotyledons and Monocotyledons. Others consider
Pteridophyta and Bryophyta to be separate classes.
Thallogens are variously divided by different writers,
and the places for diatoms, slime molds, and stoneworts
are altogether uncertain.
[1913 Webster] For definitions, see these names in the
Vocabulary.

[1913 Webster]
2. (Chem.) One of a class of caustic bases, such as soda,
potash, ammonia, and lithia, whose distinguishing
peculiarities are solubility in alcohol and water, uniting
with oils and fats to form soap, neutralizing and forming
salts with acids, turning to brown several vegetable

of the atmosphere; flying; having the power to fly. [Obs.]

aeriform state; subject to evaporation.
[1913 Webster]
Note: Substances which affect the smell with pungent or
fragrant odors, as musk, hartshorn, and essential oils,
are called volatile substances, because they waste away
on exposure to the atmosphere. Alcohol and ether are
called volatile liquids for a similar reason, and
because they easily pass into the state of vapor on the
application of heat. On the contrary, gold is a fixed
substance, because it does not suffer waste, even when
exposed to the heat of a furnace; and oils are called
fixed when they do not evaporate on simple exposure to
the atmosphere.

temper.
