(604) 682-5477 | Fax (604) 681-5305 | Website: www.MineralsEd.ca Introduction As you look around your home, it is important to think of the many things that you have and what are they made from. It’s simple - everything is made from Earth’s natural resources: rocks, soil, plants, animals, and water. They can be used in their natural state, or processed, refined and manufactured by people into other useable things. The resources that grow and can be replaced when they die or are harvested, like plants and animals, are called renewable resources. Those that cannot be regrown and replaced, like rocks, soil and water, are called non-renewable resources. All natural resources are valuable and we must use them conservatively. Mineral resources are natural Earth materials that must be mined from the ground. We use them every day, and they are non- renewable. Some are changed very little before they are used, like the rock granite for example, that is commonly used to make kitchen countertops or tombstones. Other mineral resources, like those that contain useful metals, must be processed to extract the metal ingredient. The metal is then manufactured into different parts of a product, like a toaster or a smartphone. Whether you are practicing violin in your room, eating a meal in the kitchen, watching TV in the living room or brushing your teeth in the bathroom, your daily activities use things that come from mineral resources.

  • Chapter 2 the Solid Materials of the Earth's Surface
    CHAPTER 2 THE SOLID MATERIALS OF THE EARTH’S SURFACE 1. INTRODUCTION 1.1 To a great extent in this course, we will be dealing with processes that act on the solid materials at and near the Earth’s surface. This chapter might better be called “the ground beneath your feet”. This is the place to deal with the nature of the Earth’s surface materials, which in later sections of the chapter I will be calling regolith, sediment, and soil. 1.2 I purposely did not specify any previous knowledge of geology as a prerequisite for this course, so it is important, here in the first part of this chapter, for me to provide you with some background on Earth materials. 1.3 We will be dealing almost exclusively with the Earth’s continental surfaces. There are profound geological differences between the continents and the ocean basins, in terms of origin, age, history, and composition. Here I’ll present, very briefly, some basic things about geology. (For more depth on such matters you would need to take a course like “The Earth: What It Is, How It Works”, given in the Harvard Extension program in the fall semester of 2005– 2006 and likely to be offered again in the not-too-distant future.) 1.4 In a gross sense, the Earth is a layered body (Figure 2-1). To a first approximation, it consists of concentric shells: the core, the mantle, and the crust. Figure 2-1: Schematic cross section through the Earth. 73 The core: The core consists mostly of iron, alloyed with a small percentage of certain other chemical elements.

  • Minerals for Livestock
    Station BulIetn 503 October 1951 Minerals for Livestock J. R. Haag Agrkultural Experiment Station Oregon State College Corvallis Foreword Oregon livestock producers are aware of the need for additional information on the use of mineral sup- plements.These materials frequently are purchased when not needed with the particular rations that are being used.The intelligent use of minerals pays divi- dends.Over-use may be harmful. This bulletin has been revised to give livestock pro- ducers and feed dealers the latest available information that will assist them in selecting and feeding only such materials as may be needed to supplement the natural supply already available in their feedstuffs. Although noteworthy progress is being made we believe that research must be intensified in Oregon to provide more complete information on the adequacy of minerals in feed produced in the various areas of the State.Evidence being accumulated by our research staff indicates that deficiencies peculiar to certain areas are causing serious losses among livestock. Dean and Director Minerals for Livestock By J. R. HAAG, Chemist (Animal Nutrition) Oregon State College animals require an abundance of palatable feedstuffs as a FARMsource of energy, fats, proteins, minerals, and vitamins.These feedstuffs must be suitable for the kind of livestock maintained and, in addition, must be available at a cost that will permit profitable livestock production. The mineral salts constitute only one of the groups of nutrients that play important parts in animal nutrition.Some mineral ele- ments, like calcium and phosphorus, are needed in large amounts, while others, like iodine, are required only invery minute traces.

  • 13. Nutrient Minerals in Drinking Water: Implications for the Nutrition
    13. NUTRIENT MINERALS IN DRINKING WATER: IMPLICATIONS FOR THE NUTRITION OF INFANTS AND YOUNG CHILDREN Erika Sievers Institute of Public Health North Rhine Westphalia Munster, Germany ______________________________________________________________________________ I. INTRODUCTION The WHO Global Strategy on Infant and Young Child Feeding emphasizes the importance of infant feeding and promotes exclusive breastfeeding in the first six months of life. In infants who cannot be breast-fed or should not receive breast milk, substitutes are required. These should be a formula that complies with the appropriate Codex Alimentarius Standards or, alternatively, a home-prepared formula with micronutrient supplements (1). Drinking water is indispensable for the reconstitution of powdered infant formulae and needed for the preparation of other breast-milk substitutes. As a result of the long-term intake of a considerable volume in relation to body weight, the concentrations of nutrient minerals in drinking water may contribute significantly to the total trace element and mineral intake of infants and young children. This is especially applicable to formula-fed infants during the first months of life, who may be the most vulnerable group affected by excessive concentrations of nutrients or contaminants in drinking water. Defining essential requirements of the composition of infant formulae, the importance of the quality of the water used for their reconstitution has been acknowledged by the Scientific Committee on Food, SCF, of the European Commission (2). Although it was noted that the mineral content of water may vary widely depending upon its source, the optimal composition remained undefined. Recommendations for the composition of infant formulae refer to total nutrient content as prepared ready for consumption according to manufacturer’s instructions.

  • Mineral Materials from BLM-Administered Federal Lands
    How to Obtain Mineral Materials From BLM-Administered Federal Lands Including Stone, Sand and Gravel, Clay, and Other Materials Introduction The Department of the Interior‘s Bureau of Land Man- agement (BLM) is a multiple-use land management agency responsible for administering 262 million acres of public land located primarily in the western United States, including Alaska. The BLM manages many resource programs, such as minerals, forestry, wilderness, recreation, fisheries and wildlife, wild horses and burros, archaeology, and range- land. This brochure con- tains information about the mineral materials program. Mineral materi- als include common vari- eties of sand, stone, gravel, pumice, pumicite, clay, rock, and petrified Concrete and asphalt aggregate (crushed stone) used for airport wood. The major Federal runways, highways, bridges, and high-rise buildings. law governing mineral materials is the Materials Act of 1947 (July 31, 1947), as amended (30 U.S. Code 601 et seq.). This law authorizes the BLM to sell mineral materials at fair market value and to grant free-use permits for mineral materials to Government agencies. It also allows the BLM to issue free-use permits for a limited amount of material to nonprofit organizations. How Are Mineral Materials Important to Our Society? Mineral materials are among our most basic natural resources. These materials are in everyday construction, agriculture, and decorative applications (Table 1). The United States uses about 2 billion tons of crushed stone, dimension stone, and sand and gravel every year. Our highways, bridges, power plants, dams, high-rise buildings, railroad beds, and airport runways, along with their foundations and sidewalks, all use mineral materials of one type or another.

Scope and Objectives of the Research Topic Review The objective of the Research Review “ Laboratory mineral soil analysis and soil mineral management in organic farming ” is to draw together all the available relevant research findings in order to develop the knowledge and expertise of organic advisers and thereby to improve soil management practice on organic farms. The Review will concentrate on N, P and K and: 1. Identify all the relevant research undertaken 2. Collate the results of research and summarise the findings of each project 3. Draw on practical experience 4. Analyse the research and summarise the conclusions in a form that is easily accessible by advisers and can be used to help them select appropriate soil analytical techniques and to interpret the results and provide practical advice to farmers on soil management and amendments. 2. Introduction to measuring soil fertility in organic farming. The capacity to improve the fertility of a given soil through management is inextricably linked to the inherent properties of that site – soil texture, mineralogy, slope and climate. Ideally soil fertility should be assessed for the soil in situ , in the field/farm context, rather than as a list of properties of an isolated sample.
