Introduction
Md. Nayem Hasan Munna, the founder of “Earth Review,” is currently pursuing a Ph.D. at The Ohio State University in the United States. He obtained his M.S. and B.S. degrees in Soil and Environmental Sciences from the University of Barishal (BU) in Bangladesh. In recognition of his exceptional academic accomplishments, he was awarded the National Science and Technology (NST) Fellowship by the Ministry of Science and Technology, Bangladesh, for the academic year 2021-22.

Paira is one of the largest rivers in the Patuakhali district that divides Patuakhali and Barishal districts. Chinese contracting organization Longjian Road and Bridge Company Ltd have been contracted for the construction of the bridge. The environmental impact value of this project is “–2” (negative two). Different environmental management plans a...

Soil and Biochar were incubated for 30 days at 10 days of intervals.
Results:
Level of soil pH: 10 days>20 days<30 days
Level of soil TOC (Total Organic Carbon): 10 days>20 days<30 days
Note: pH and TOC at 30 days were not higher than 10 days of incubation.
What could be the explanation for higher and lower at different incubation periods?
Regards,
Nayem
Biochar carbon content and pyrolysis temperature relationship?
Typically, biochar organic carbon content increases with increasing pyrolysis temperature. But, I found the carbon content decreases with increasing temperature. What could be the explanation?
Note: I used pineapple crown biochar to prepare biochar and I used the Black and Walkley method to determine the carbon content that is used to assess soil organic carbon as I do not have a CHN analyzer facility.
Incubation study of soil and biochar and changes in soil EC (electrical conductivity) throughout the incubation period.
The farmers of Bangladesh would like to use inorganic fertilizer in their lands to get an effective outcome. That is true that using inorganic fertilizer is really helpful to grow more crops. But, the use of some fertilizers, especially N fertilizers and pesticides can boost the activities of soil microbes! The chemical fertilizers provide the microbes with easy to use N compounds.
The causes of riverbank erosion:
- Flood: Bangladesh is a riverine country. About 700 rivers including tributaries flow through Bangladesh constituting a good waterway of total length around 24,140 kilometers. Most of the country’s land is formed through silt brought by the rivers. In our country, every year the people are affected by floods, especially for a rainy reason. This is the most crucial reason for riverbank erosion.
- Deforestation: Deforestation refers to the cutting down trees and makes a forest non-forest. Trees can hold on the soil aggregates. But when the trees are cut down, the soil particles become loose and for this reason, the soil of the river bank can be eroded gradually.
- Heavy Rainfall: We are in monsoon climate zone. We face heavy rainfall in the rainy season. This extreme rainfall is also an important cause of riverbank erosion. Where there is no well-constructed levee of a river, the soil can be eroded because of heavy rainfall at that time. Source: https://www.earthreview.org
