improvement of soil properties through sustainable agriculture requires suitable management of plant residues. this study was conducted to investigate the effect of different types and managements of plant residue on soil physical properties in a field experiment as factorial based on rcbd with three replicates. the first factor was residue type including barley straw and alfalfa residue, and t...
درک الگوی توزیع مکانی ماکروفون خاک بدلیل اثرات آن روی فرآیندهای اکوسیستم بسیار مهم است. لیکن اطلاعات کمی در این خصوص وجود دارد. درمورد تنوع زیستی ارگانیسم ها وجانداران خاکزی که ازاجزای مهم وکلیدی درهرسیستم اکولوژیکی هستند و در بهبود حاصلخیزی خاک و تولیدات زمین وپایداری اکوسیستم ها(ازطریق فرآیندهای بیولوژیک)نقش عمده دارند تحقیقات کمی انجام شده است. این تحقیق جهت بررسی الگوی مکانی پارامترهای تنوع...
Meghalaya is a state of the north eastern region which is recognized as a treasure of many valuable minerals. Mining operations were left to the local miners to take up coal mining as cottage industries since most of the coal deposits are small and isolated and were not amenable for scientific mining to be conducted in the organized sector. The study of soil physical properties has been done be...
Soil stabilization has become a major issue in construction engineering and the researches regarding the effectiveness of using industrial wastes are rapidly increasing. The present experimental work briefly describes the suitability of the locally available Rice Husk Ash (RHA) to be used in the local construction industry in a way to minimize the amount of waste to be disposed to the environme...
This paper presents promising new technologies for soft ground improvement which include the low improvement ratio cement column method (LCC) and the lightweight banking method using foam mixed soil (LFS). As a measure to reduce settlement and lateral deformation due to road embankment loading on soft ground, the column type deep mixing method used at a low improvement ratio of around 10-20% th...
