SOILS
The main factor that has influenced the development of soils in
Bhir district is the undulating and hilly topography. The soils of
varying depth are to be found throughout the district. The deep
soils usually lie in the river valleys. The district is covered
with the Deccan trap soil.
The profiles of the different kinds of soils in the district are
given in Table No. 5. The following are some of the important
varieties of soil in this district.
Shallow Soils
The shallow soils of Bhir district (Profile Nos. 1 and 2) have
dark brown to dark yellowish brown colour, single grain to blocky
structure and sandy loam to loamy texture. The PH of the soil is
from 8.3 to 8.5 with total soluble salts of 0.2 to 0.3 per cent.
The calcium carbonate is as much as 20 per cent in profile No. 1
whereas it is 5 per cent in profile No. 2. The organic matter
varies from 0.52 to 0.84 per cent. The exchangeable calcium varies
from 43 to 46 m.e. per cent, magnesium 5 m.e. per cent and sodium
and potassium together about 1 m.e. percent.
The percentage of nutritious contents in shallow soils is very
low: Nitrogen varying between 0.02 and 0.05 per cent. P2 O5
between 9 and 11 mgm. per cent and K2 0 up to 38 mgm per cent.
These soils respond to all kinds of fertilisers.
Moderately deep Soils
The moderately deep soils are found in profile Nos. 3 to 5 and
have varying colours, structure and texture. The colour of the
soil is dark brown, dark reddish brown or dark grey brown. The
structure varies from single grain to blocky while texture varies
from sandy loam to clay. The PH varies from 7.5 to 8.5 and total
soluble salts from 0.2 to 0.4 per cent. The calcium carbonate
varies from 2 to 20 per cent and organic matter from 0.92 to 2.37
per cent. The base exchange capacity of the soils is high with
exchangeable calcium from 21 to 62 m.e. per cent, magnesium from 5
to 15 m.e. per cent and sodium and potassium together from 1 to 2
m.e. percent.
Like shallow soils, these soils also are of inferior quality due
to the lack of nutritious contents in them. Nitrogen is found only
in soils in profile No. 4 and that too in very small quantity of
about 0.14 per cent. The phosphate contents are between 10 and 18
mgm. per cent. Potash is found up to 28 mgm. per cent. Generally
speaking, these soils respond to all kinds of fertilisers.
Medium deep Soils
The medium deep soil is found in profile Nos. 6 to 8. It has dark
brown or black colour, and is granular or blocky in structure, and
sandy loam to clayey in texture. The PH of this soil
varies from 8.2 to 8.7 and total soluble salts from 0.2 to 0.3 per
cent. The contents of calcium carbonate and those of organic
matter vary widely from 3 to 20 per cent, and from 0.48 to 2.16
per cent, respectively. The base exchange capacity of the soil is
fairly high with calcium from 22 to 54 m.e. per cent, magnesium
from 11 to 25 m.e. per cent and sodium and potassium together from
1 to 2 m.e. percent.
The nutritious elements in the soil also vary considerably. Thus
in profile No. 8, there is more of nitrogen and potash than other
elements. This type of soil responds favourably to the nitrogenous
and phosphatic fertilisers.
Deep Soils
These soils are to be found in profile Nos. 9 to 11. Their colour
changes from dark brown to black and so also the texture changes
from clay loam to clayey. The PH of these soils vary from 8.5 to
8.9 and total soluble salts from 0.4 to 2 per cent. The high PH
and the total soluble salts show that the soils have developed the
saline and alkaline conditions which are pronounced in the profile
No. 11. The base exchange capacity is a little high with calcium
varying from 22 to 42 m.e. per cent, magnesium from 13 to 29 m.e.
per cent and sodium and potassium together from 2 to 15 m.e.
percent.
The plant nutritious contents in the soil are low with nitrogen
0.04 per cent, phosphate between 9 and 15 mgm. per cent and potash
between 31 and 41 mgm. per cent. This soil responds to nitrogenous
and phosphatic fertilisers.
