M Amirul Islam (1918-2001) was a Bangladesh academic, researcher, and scientist. He developed the Seven Soil Tracts system, a classification of the soil of Bangladesh, which is the foundation of agriculture and soil management in Bangladesh. [1]
Creep has caused the soil to spread over this pavement. Creep can also be caused by the expansion of materials such as clay when they are exposed to water. Clay expands when wet, then contracts after drying. The expansion portion pushes downhill, then the contraction results in consolidation at the new offset. Objects resting on top of the soil ...
Soil Resources Development Institute (SRDI) is a government organization under the Ministry of Agriculture working as a statutory organization that carries out research on soil and surveys on soil quality to improve agriculture in Bangladesh and is located in Dhaka, Bangladesh.
Agriculture is the largest employment sector in Bangladesh, making up 14.2 percent of Bangladesh's GDP in 2017 and employing about 42.7 percent of the workforce. [1] The performance of this sector has an overwhelming impact on major macroeconomic objectives like employment generation, poverty alleviation, human resources development, food ...
Bangladesh Agricultural University (BAU) is the second largest public university in Bangladesh.Its expansive campus, covering an area of 5.10 square kilometers (1.97 sq mi), is situated in rural-urban mixed surroundings within Mymensingh Sadar Upazila, approximately 3 kilometers (1.9 mi) south of the metropolitan city Mymensingh.
Soil erodibility is a lumped parameter that represents an integrated annual value of the soil profile reaction to the process of soil detachment and transport by raindrops and surface flow. [1] The most commonly used model for predicting soil loss from water erosion is the Universal Soil Loss Equation (USLE) (also known as the K-factor ...
[34] [35] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [36] [37] [38] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...
The first modern theoretical models for soil consolidation were proposed in the 1920s by Terzaghi and Fillunger, according to two substantially different approaches. [1] The former was based on diffusion equations in eulerian notation, whereas the latter considered the local Newton’s law for both liquid and solid phases, in which main variables, such as partial pressure, porosity, local ...
