Four elements‚ hydrogen‚ carbon‚ oxygen and nitrogen‚ are the major components of most organic compounds. Consequently‚ our understanding of organic chemistry must have‚ as a foundation‚ an appreciation of the electronic structure and properties of these elements. The truncated periodic table shown above provides the orbital electronic structure for the first eighteen elements (hydrogen through argon). According to the Aufbau principle‚ the electrons of an atom occupy quantum levels or orbitals starting

Phoenix Organics is a company that’s goal is to make a difference to the community‚ to the planet and to the health of its people. Their vision was to create something that would be good for the planet and good for the health of its people. And so in 1987 Chris Morrison‚ Roger Harris and Deborah Cairns created the first Phoenix product. The company started with a drink called "Ginger Fizz"‚ a naturally fermented product that was often determined to get out of the bottle before the top was cracked

Organic agriculture‚ seen as a niche agriculture sector‚ is promoted as an effective and sustainable approach to food security‚ farmer’s profit instigation‚ and resource management. Aside from organic farming‚ the Department of Agriculture welcomed agricultural activities that encouraged active in the preservation of the environment‚ such as agriculture tourism and ecotourism as an additional initiative for agricultural development.

how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire‚ the science of Organic chemistry did not develop until the turn of the eighteenth century‚ mainly in France at first‚ then in Germany‚ later on in England. By far the largest variety of materials that bombard us are made up of organic elements. The beginning of the Ninetieth century was also the dawn of chemistry‚ all organic substances were understood as all being materials

Before I go on about the use of fertilizers in organic farming‚ you must first understand what organic farming is. The simplest way to describe organic agriculture is agricultural production without the use of synthetic chemicals (fertilizers‚ pesticides‚ antibiotics‚ etc). For crop production‚ organic materials such as compost and manure are used to maintain soil organic matter and as sources of nutrients. Nitrogen-fixing as well as pest resistant plant varieties are utilized. The incorporation
