Summary: The primary crop in Bangladesh is rice, and the rice yield is affected by arsenic buildup in the soil from irrigation. Soil testing using an inexpensive kit can help farmers identify high-arsenic areas for mitigation or crop switching decisions. By comparing kit measurements with X-ray fluorescence measurements, it was found that farmers can accurately determine arsenic levels in their fields using a Bayesian approach or linear regression.

Summary: This study investigated the influence and mechanism of biochar application on ammonia volatilization in paddy fields. The results showed that biochar application reduced cumulative ammonia volatilization, increased NH4+-N content in soil and soil solution, and enhanced soil urease activity. Ammonia volatilization was significantly correlated with nitrogen concentration and soil urease activity. Additionally, biochar application increased the abundance of ammonia-oxidizing bacteria and ammonia monooxygenase subunit A. Long-term biochar application may have a strong potential to inhibit ammonia volatilization.

Summary: Water wastage is a serious issue in irrigation, but it can be eliminated by using a well-structured fuzzy rule base. Poyen's fuzzy logic controlled automatic irrigation system efficiently manages water requirements by considering evapotranspiration loss and cultivating conditions. The system consists of a wireless sensor network and an information processing module, which work together to ensure the field receives the optimum volume of water. Field testing and simulation output show promising improvements in water management and crop yield.

Summary: Evidence suggests that controlled irrigation (CI) and biochar application (BA) have an impact on soil microbial genes related to nitrogen conversion in paddy fields. The application of biochar increases the abundance of nitrogen-fixing bacteria, leading to higher levels of ammonium and nitrate in the soil. Moreover, biochar treatment also increases the microbial diversity in the paddy field. The combined use of CI and BA affects soil nitrogen content, temperature, pH, and electrical conductivity, which in turn affect microbial genes related to nitrogen transformation.

Summary: This study conducted a hydrogeochemical investigation on well water samples from the extent of Karfiguela paddy field. The results showed that the shallow groundwater in the area is suitable for irrigation, with low physical parameters and ion concentrations. However, elevated levels of Cd and NO3- were detected, posing slight to moderate risks. It was also found that the groundwater's mineralization is mainly influenced by anthropogenic agricultural activities, calcite and magnesite alteration, and CO2 dissolution process.

Summary: The impact of Ar/N2 flow rate and RTA on CoNxOy ceramic films for pH sensors was studied, showing that films prepared at 20/10 flow rate had higher Co3+ content and rougher surface. The EGFET sensor fabricated at 20/10 flow rate with RTA at 300°C exhibited high pH-sensitivity, low drift rate, and low hysteresis voltage due to film characteristics.

Summary: Traditionally, topographic depressions in Digital Elevation Models (DEMs) were considered as artifacts and removed completely prior to modeling. However, the effects of depression filling on river network structure and surface runoff were not clear. This study used 2D hydrodynamic modeling to evaluate these effects and found that removing depressions from DEMs is unnecessary and they should be taken into account in simulating drainage patterns and hydrologic response.
