Although human exposure to arsenic is thought to be caused mainly through arsenic-contaminated underground drinking water, the use of this water for irrigation enhances the possibility of arsenic uptake into crop plants. Rice is the staple food grain in Bangladesh. Arsenic content in straw, grain and husk of rice is especially important since paddy fields are extensively irrigated with undergro...
Technology intervention is a key success to restore properties and productivities of a highly weathered soil (Oxisols). The main challenge is to find materials with the ability to generate soil negative charge, release various nutrients and suppress toxic elements. The objective of this study was to increase negative charge and nutrient content, and suppress Al and Mn toxicities of an Oxisol us...
Good quality planting materials for yam cultivation is a major challenge and adapting the most preferred local varieties to high ratio propagation methods such as vine cutting could help ameliorate this constraint. An experiment was conducted in screen house at CSIR-Savanna Agricultural Research Institute assess response of ‘Labako’, ‘Nyamenti’ ‘Kpamyo’ (check) under different substrates. The 3...
Soil stabilization is the alteration of property of locally available soil to improve its engineering performance. Stabilization can increase the shear strength of soil and control shrink – swell properties of soil, thus improving the load bearing capacity of a sub grade to support the pavements and foundation. The objective of this paper is to expose the possibilities of paper sludge and rice ...
this research was conducted on polluted soil near the lead and zinc factory in zanjan province through which the effects of two organic and three mineral sources were examined on heavy metals fixation in randomized experiment design. experimental treatments includes bagasse and rice husk in three levels: 1.25, 2.5 and 5%, zeolite in three levels: 5%, 10% and 15%, phosphate rock in three rates: ...
can be completely dispensed with. The standard pattern of jail filth receptacle answers admirably. This is made easy by the fact that I have dispensed with the system of " earth proofing " each deposit in the latrines, and substituted paddy husk instead. To us here, this item is a bye-product in our garden department; we produce 80 maunds of rice locally, and it is found by experiment that a po...
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Over the past few decades Road infrastructure in India is developing at a quick pace. A decent pavement is required for the safe, comfortable and prudent development of traffic. The thickness of road relies on geotechnical properties of subgrade so...
Use of soft clay soils in construction activities has faced many problems. Some improvement, stabilization, and reinforcement methods is required to use these soils in body of roads, sub-foundations and embankments. In this research, the effect of chitin nanofiber and rice husk ash as additives on the behavioral properties and bearing resistance of soft clay soils by considering the processing ...
drain envelopes play significant roles in the performance of drainage systems due to theirreduction in letting sediments into the drainpipes and also because of an increase in thehydraulic conductivity of soil around the drainpipes. throughout the present research, theeffect of a one 1000 hour flow on dual envelopes consisting of geotextile as a means ofimproving the hydraulic gradient and rice...
