Abstract:
The soil samples were collected at different
depths from 48 locations at 16 thanas under 7 districts. The soils were
silt loam and silty clay loam in texture. The pH of the soils varied
from 4.9- 7.9, 4.9-8 and 5.0-7.9 at D1 D2 and
D3 depths, respectively. The highest pH value of 8.0 was
found at Saramongal from Rajair thana under Madaripur district at D2
depth. On the basis of 0-45 cm depth, an average pH values for 7 districts
can be placed in the following order: Gopalgonj > Rajbari > Madaripur
> Faridpur > Moulavibazar > Habigonj > Sylhet. Most of the
soils were slightly alkaline in reaction. The organic matter content
in soils ranged from 0.69-2.45%, 0.51 - 2.73%, 0.89 -2.83%,
0.83 - 2.56%, 0.55 - 1.98%, 0.51 - 2.00% and 0.55
- 2.45% in Gopalgonj, Faridpur, Rajbari, Madaripur, Moulavibazar,
Habigonj and Sylhet districts, respectively. The highest organic matter
(2.83%) was found in Tipuragram at Rajbari Sadar thana under Rajbari
distirct at D1 depth (0 - 15 cm) and the lowest organic
matter (0.51%) was found in Pitua at Nabigonj thana under Habigonj district
and Deura in Faridpur district at D3 depth (30 - 45
cm). The EC value of Gopalgonj, Faridpur, Rajbari, Madaripur, Moulavibazar,
Habigonj and Sylhet district soils ranged from 1.73 - 2.83, 1.24
- 3.84, 1.45 - 2.01, 1.30 - 3.52, 0.27 - 0.90,
0.37 - 0.41and 0.26 - 1.17 dsmG‾1 , respectively.
An average EC values for 7 districts can be placed in the following
order: Gopalgonj > Madaripur > Faridpur > Rajbari > Moulavibazar
> Sylhet > Habigonj. Most of the soils were alkaline in nature
and it may be reduced through the application of Gypsum and other practices.
