WATER CONSERVATION INTRODUCTION: Water is essential for life on earth. Water is needed for growing food‚ keeping ourselves clean‚ generating power‚ controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it. Water conservation – Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning‚ manufacturing‚ and agricultural irrigation

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

Types of Soil & Their Uses Soil is a complex system of organic and inorganic matter that directly and indirectly supports plant and animal life. It is comprised of minerals‚ nutrients‚ water‚ microorganisms and decomposed living matter that provide the essential elements required to sustain growth. The soils of different geographical areas differ in chemical makeup‚ structure‚ pH value‚ texture and color. Soil makes the basis of the ecosystem and performs functions essential for the survival

Determining the Plastic Limit and Plasticity Index of Soil (Referenced Document: ASTM D 4318) OBJECTIVE: To determine the plastic limit and plasticity index of soil. APPARATUS AND SUPPLIES Evaporating dish Spatula Ground-glass plate—at least 30 cm (12 in.) square by 1 cm (3⁄8 in.) thick for mixing soil and rolling plastic limit threads Balance (with accuracy to 0.01 g) Containers Oven PREPARATION OF TEST SPECIMEN Select a 20-g portion of soil from the material prepared for the liquid limit

While the nature takes from 100 to 400 years to build one centimetre of top soil‚ man can and often does destroy it almost overnight by haphazard land use and improvident husbandry. Irrational methods of cultivation‚ deforestation‚ destruction of natural vegetation due to overgrazing by pasturing animals etc.‚ accelerate denudation. Besides‚ failure of rains‚ floods‚ depopulation and loss of cattle caused by famine and pestilence‚ disturbance caused by war and interference with or change

WATER CONSERVATION Water conservation encompasses the policies‚ strategies and activities to manage fresh water as a sustainable resource to protect the water environment and to meet current and future human demand. Population‚ household size and growth and affluence all affect how much water is used. Factors such as climate change will increase pressures on natural water resources especially in manufacturing and agricultural irrigation. The goals of water conservation efforts include as follows:

Joe Garcia PTAC-1308 Energy Conservation It would be hard to imagine a life without the use of energy. So many of the products that we use on a daily basis are powered because of electricity‚ which in turn is generated because of energy. American’s use a mixture of different energy sources to cool and heat our homes‚ offices‚ and means of transportation. We also use energy sources to illuminate and power these same places. Oil has provided the United States with less than 50% of energy needs

extreme form of soft soil. It is an organic soil which consists more than 75% of organic matters. However‚ the cutoff value of the percentage of organic matter necessary to classify a superficial deposit or soil as peat varies throughout the world‚ usually depending on the purpose of classification. This cutoff value also serves to differentiate peat from superficial deposits or soils with lesser amounts of organic content. The terms peat and organic soils‚ used for describing soils with an organic content
