Mapping of soil properties is an important operation as it plays an important role in the knowledge about soil properties and how it can be used sustainably. The study was carried out in a local government area in Bangladesh in order to map out some soil properties and assess their variability within the area. From the study area, a total of 92 soil samples (0–20 cm) were collected from different cropping patterns at an interval of 2.2 × 2.2 km2 on a regular grid design. A portable global positioning system (GPS) was used to collect coordinates of each sampling site. Then, soil properties, that is, pH, electrical conductivity (EC), soil organic carbon (SOC), total nitrogen (Total N), and soil available nutrients (P, K, and S) were measured in the laboratory. After the normalization of data, classical statistics were used to describe the soil properties, and geostatistical analysis was used to illustrate the spatial variability of the soil properties by using kriging interpolation techniques in a GIS environment. Results show that the spatial distribution and spatial dependency level of soil properties can be different even within the small or large scale. According to cross-validation results, for most soil properties, the kriging interpolation method provided the least interpolation error. The generated maps of soil properties that indicate soil nutrient status over the study region could be helpful for farmers and decision-makers to enhance site-specific nutrient management. Also, these prototype maps would be helpful for future nutrient and fertilizer applications management, including a site-specific condition to not only reduce the cost of input management but also prevent any environmental hazard. It also demonstrates that the effectiveness of geostatistics and GIS techniques provided a powerful tool for this study in terms of regionalized nutrient management.

Southwestern region of Bangladesh is very rich in floral diversity, and their diversified uses. An extensive survey was conducted to investigate ethnobotanical applications of botanical species by the community of Khulna, Bangladesh. We focused on plants and community relationships, identify the most important species used, determine the relative importance of the species surveyed and calculated the Fidelity level (FI) and Cultural Significance Index (CSI) concerning individual species. In total, we have listed 136 species of 114 genera under 52 families, of which 41% (63) species were utilized as food, followed by 30% (45) medicine, 14% (21) constructional timber, 11% (17) ornamental, and 4% (6) other uses. Inheritance of traditional knowledge of medicinal plants was the primary source of knowledge acquisition through oral transmission over the generations. However, only 34% of the informants were traditional herbal practitioners. Most of the medicinal uses are primly associated with anti-inflammatory, anti-microbial, antiseptic, expectorant, antidote, fever reduction, and pain relief.
