— ❧ —Soil fertility, nano-technology, and urban air quality — simultaneous research across Bangladesh's leading institutions.
Bentonite-Biochar Coated Urea & Nitrogen Use Efficiency
Synthesising BBCU from rice husk biochar (pyrolysed at 550°C), sodium bentonite, and corn starch binder. N-release kinetics modelled via Higuchi and Korsmeyer-Peppas equations. Running soil incubation, 50 cm leaching columns, and jar-based volatilisation experiments simultaneously.
Full Research DetailsNano Urea vs. Conventional Urea on Wheat
24-pot CRD experiment on BARI Gom 33. Comprehensive NUE indices, Kjeldahl N, tissue nutrient quality (AAS + ICP-OES), and post-harvest soil dynamics despite a hailstorm mid-experiment.
PM₀.₁ & Heavy Metal Characterisation
Ultrafine particulate matter sampling with Nanosampler II (Kanomax 3182) and heavy metal analysis via AAS in Dhaka's urban environment. Ecological risk index assessment ongoing.
Words from the Field
— ❧ —Writing across soil science, urban ecology, field notes, and personal reflection — on Blogger, with 13,000+ readers.
The Slow Chemistry of Soil Nitrogen
How nitrogen moves through soil, how it is lost to the atmosphere and waterways, and why slow-release coatings are changing the equation for South Asian rice paddies.
Read on BloggerWhen a Hailstorm Hits Your Experimental Plots
A first-person account of watching a hailstorm destroy months of field work — and how a research pivot turned disruption into a richer dataset.
Read on BloggerWhy Dhaka's Urban Farmers Are Choosing Organic
Urban farmers across Dhaka are turning away from synthetic inputs. A ground-level look at the economics, the soil science, and the culture behind the shift.
Read on BloggerScience does not move in a straight line. It loops, it backtracks, it survives hailstorms. What matters is that you keep measuring.Sajjadur Rahman — Field Notes, 2024
