“…In general, SOC was higher in low lying areas, the single cropped zones, which remain 5-6 months under water in a year. This level of SOC specifically in about 18% areas of the country is still inadequate for satisfactory crop production [16]. As population pressure is increasing, farmers are using such lands to increase total production through cropping intensification resulting in depletion of SOC along with other plant nutrients.…”

“…Although available P in the category of very low and low cover a larger area (about 70%), in some areas its high has taken place ( Fig. 1b) because of cropping patterns followed, fertilizer management options and inherent characteristics of parent materials [16,21]. As a greater area suffers from available P, corrective measures have to be taken for profitable production [22].…”

“…Since farmers generally use more N fertilizer and minimum K rate, the later is depleting rapidly in many areas of Bangladesh [21,22,24]. In the global perspective, K is also depleting by 38.8 kg ha -1 yr -1 [23]; although its (a) (b) build up is not either uncommon in some areas because of excessive use with certain crops [16].…”

“…The depletion of soil fertility in areas with high cropping intensities [27] indicated that replenishment of removed nutrients were not taking place or it is beyond the capacity of the soils to supply major nutrients for growing high yielding crop varieties. There are evidences that Zn and B contents have been depleted severely from 1991 to 2012 in some selected areas of Bangladesh and thus crop productivity is declining [16].…”

Determination of soil fertility with minimum data set for crop zoning and devising fertilizer recommendations as well as soil fertility evaluation method based on soil properties. The data were collected from existing literatures and scoring was done on 0-100 scale. The lowest score was assigned for the minimum value of tested attributes and then gradually higher scoring values. Arithmetic, weighted, geometric and most minimum of mean scores were calculated and their performances were compared with grain yield of dry season irrigated (Boro) rice. Soil fertility in 10-12 and 39-52% areas in Bangladesh are very low and low, respectively. Medium fertile and fertile soils are distributed in 17-41% and in about 8% areas of the country. About 55% soils scored 70- AJSSPN, 4(4): 1-11, 2019; Article no.AJSSPN.50268 2 95 (medium to high SOC) and the rest belongs to inferior quality. In some areas P build up has taken place (25% areas), but widespread K mining. Sulphur and Zn status in about 40% areas are low to very low (scored <35 and <40). Soils of the major areas of the country are with low pH (5.0-6.0) and CEC in the range of 15-25 cmol c kg -1 . Weighted mean score and most minimum of eight attributes score showed good relationships with dry season irrigated rice yields than other tested methods indicating that this technique can be used for soil fertility rating in tropical countries.

Brick is the most common construction material that we use for the construction of buildings and structures all over Bangladesh. To supply the brick locally, many brickfields have emerged all over the country. The production of brick has seasonal, environmental, social and biological impact. The adverse pollution effect of the brick production process is increasing every year as the brick production and number of brick kilns are increasing day by day. A life cycle assessment or LCA analysis has been carried out to evaluate the overall impact of brick manufacturing process on environment and human health in Rajshahi region. The LCA software OpenLCA 1.11.0 was used to carry out the study with a scope from "cradle to gate" of LCA methodology. We focused on the potential environmental burden, including resource depletion, air pollution, water pollution, soil pollution and adverse effects on human health and crop production. The brick manufacturing phases of 20 brick fields are assessed through interviews, questionnaire surveys and in-situ observations. We also focused on the management system of the brickfields to assess the mismanagement and safety issues. We also compared the environmental effect and mismanagement on the brick manufacturing process to find the correlation between them. Based on the major findings from our study, some recommendations are proposed to mitigate the problems. The main recommendations include the use of eco bricks, recycled bricks, modified kiln systems, alternative firing technologies, training programs and a safe working environment.

A study was aimed to delineate the micronutrient status, their change directive with time and relationship with other soil variables in piedmont soils of Bangladesh. Northern and Eastern Piedmont Plains (AEZ 22) is one of the 30 agro-ecological zones (AEZs) of the country whose bench mark status of soil micronutrient has been used for comparing with the present status. There is an indication of zinc (Zn) and boron (B) depletion to some extent after a decade of time whereas the very high fertility status of copper (Cu), manganese (Mn) and iron (Fe) prevails as it was in the previous status. In general view, the micronutrient content of surface soil (0-15 cm) was higher than those of sub-surface soils (15-30 cm). In surface soil clay content showed significant correlation with soil Zn (r=0.403**), Cu (r=0.752**), Fe (r=0.501**) and Mn (r=0.340**). Cu content of soil exhibited positive relationship with all the soil parameters except soil pH and P content; there existed highly significant negative correlation of Cu with soil pH (r=-0.578**) and P (r=-0.420**). The availability of Fe in soil was strongly related with soil clay content (r=0.501**), soil pH (r=-0.686**) and organic matter content (r=0.527**). In surface soil, Fe content influenced significantly with the content of Zn, Cu and Mn. Accordingly in sub-surface soil, positive significant interaction of Zn-Fe, Cu-Fe, Cu-Mn and Fe-Mn was observed. The message revealed from this study concerning nutrient depletion, and interactions among different soil parameters and nutrient elements will pave the way for efficient use of soil resources in a sustainable way.
