1. Black soils The principal region of black soils is the Deccan plateau and its periphery extending from 8°45’to 26o north latitude and 68o to 83o45’ east longitude. They are formed from Deccan basalt trap rocks and occur in areas under the monsoon climate‚ mostly of semi-arid and sub-humid types. The overall climate of black soil region may be described as hot and dry summer‚ 40-100 cm rainfall per annum‚ mild to moderate winters and annual temperature ranges from 24-30o centigrade‚ mean maximum

SOIL NAILING FOR STABILIZATION OF SLOPES Abstract: After its development in early 1980’s it become widely used in method of providing permanent and temporary support for earth‚ and stabilization of slope on many engineering projects in world wide. In starting of this period soil nailing was only performed on that project where geotechnical contractor provide this as an alternative to other soil improvements techniques. Now a days soil nailing is accepted only because of its performance and effectiveness

How to Prevent Soil Erosion TERRACING Terrace farming is a farming method that makes use of a hill to create a multiplatform farm. There are severals steps known as andenes which are built into the side of a hill. The idea behind it is that any rain that falls and builds up on the andenes will overflow into another andene below‚ making the most out of the nutrients it provides. CROP ROTATION The successive planting of different crops on the same land to improve soil fertility and help

Systems Submission date: 22/10/2010 Semester: Fall 2010 Title: How soil management can affect soil quality Introduction Three Labs 1‚ 2 & 3‚ compared three agricultural fields with different soil management histories‚ trying to find out how these different soil managements affected the measured soil parameters. The three different soil management histories are given below: a. Corn field: tilled every year after corn harvest and left bare

substances and organisms which are poisoned by toxic materials. Another way to eradicate the problem of water pollution is to reduce air and land pollution. Everyone knows that water pollution very often is caused by air contamination‚ because water moves through the air. Besides‚ when the soil is denudated it adds silt as a pollutant. Today people begin understanding that the pollution of coastal areas poses a threat to human health. Because tap water supplies are taken from reservoirs and ground waters

Soil Mechanics Soil is the most misunderstood term in the field. The problem arises in the reasons for which different groups or professions study soils. Soil scientists are interested in soils as a medium for plant growth. So soil scientists focus on the organic rich part of the soils horizon and refer to the sediments below the weathered zone as parent material. Classification is based on physical‚ chemical‚ and biological properties that can be observed and measured. Soils engineers think

1. INTRODUCTION The stability and life of any structure – a building‚ an airport‚ a road‚ dams‚ levees – depend on the stability‚ strength‚ and deformation of soils.[1] Unfortunately‚ due to the uncertainties of the world’s natural materials‚ the study of geotechnical engineering‚ and soil mechanics in particular‚ is both challenging and necessary. The following report is a compilation of the results acquired as a result of two laboratories performed by Group 13 at McMaster University on February
