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]
Downhill creep, also known as soil creep or commonly just creep, is a type of creep characterized by the slow, downward progression of rock and soil down a low grade slope; it can also refer to slow deformation of such materials as a result of prolonged pressure and stress.
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.
There are 166 tea estates in Bangladesh, covering almost 280,000 acres of land. Bangladesh is the 9th largest Tea producer, producing around 2% of the world’s Tea production. Because of Bangladesh's fertile soil and normally ample water supply, rice can be grown and harvested three times a year in many areas. [3]
An agricultural drainage system is a system by which water is drained on or in the soil to enhance agricultural production of crops. It may involve any combination of stormwater control, erosion control , and watertable control .
Since the origin of agriculture, humans have understood that soils contain different properties which affect their ability to grow crops. [4] However, soil science did not become its own scientific discipline until the 19th century, and even then early soil scientists were broadly grouped as either "agro-chemists" or "agro-geologists" due to the enduring strong ties of soil to agriculture.
A catena in soil science is a series of distinct but co-evolving soils arrayed down a slope. [1] Each soil type or "facet" differs somewhat from its neighbours, but all occur in the same climate and on the same underlying parent material. A mature catena is in equilibrium as the processes of deposition and erosion are in balance.
The benefits of improving soil structure for the growth of plants, particularly in an agricultural setting, include: reduced erosion due to greater soil aggregate strength and decreased overland flow; improved root penetration and access to soil moisture and nutrients; improved emergence of seedlings due to reduced crusting of the surface; and ...
