According to the 2001 regulations, organic is taken to mean grown and prepared without the use of synthetic chemicals, sewage sludge (as fertilizers), or ionizing radiation. Synthetic pesticides, defoliants, fertilizers, and herbicides are forbidden. 

Sulfuric acid is number one in synthetic chemical production. It is used to produce phosphate fertilizer, high octane gasoline, and a wide variety of inorganic and organic chemicals. Large quantities are consumed to pickle steel (cleaning and removal of surface oxides) disposal of spent pickling liquor can be a problem. 

While there are machines that can place seeds in all 128 cells of the tray simultaneously I have the students sow the seeds by hand. It is a little slower, but is a contemplative process that is conducive to conversation. As the class sows the pepper, tomato, basil, and eggplant seeds, the questions emerge out of the silence. Sang Min, who has happily been using synthetic fertilizers for many years, asks, What is wrong with chemical fertilizers And, what is the organic alternative ... 

Chemical fertilizers Synthetically produced mineral forms of nitrogen, phosphorous, and potassium given to plants to enhance growth. Require large amounts of fossil fuels for synthesis. 

There are approximately 16 million known chemical compounds, the majority of which are not found in nature. Although many of the known compounds are of little use or importance, some of them would be difficult or almost impossible to live without. Try to visualize living in a world without concrete, synthetic fibers, fertilizer, steel, soap, glass, or plastics. None of these materials is found in nature in the form in which it is used, yet they are all produced from naturally occurring raw materials. All of the items listed and an enormous number of others are created by chemical processes. But created from what ... 

The food supply could be increased due to the use of different hybrid varieties, improved techniques of farming, better seeds, insecticides and herbicides for the eradication of parasites and weeds, but mostly due to the intensive use of natural and synthetic fertilizers. Therefore, the dependence on chemical fertilizers, especially those containing nitrogen, is a hallmark of high-intensity agriculture and since 1960 the worldwide rate of application of nitrogen fertilizers has been increasing (Tilman, 1998). 

The motivations for organic production include concerns about the economy, the environment, and food safety. Although all organic farmers avoid synthetic chemicals in their operations, they differ in how they achieve the ideal system. Organic farmers span the spectrum some completely eschew external inputs and create on-farm sources of compost for fertilization and encourage the activity of beneficial insects... 

To sell a product as organic the crop must have been raised on land that no synthetic chemical (including fertilizers, herbicides, insecticides, or fungicides) inputs were applied for three years... 

By far the most important compound of potassium is potassium chloride (usually referred to as potash ). At least 85 percent of that compound is used to make synthetic (artificial) fertilizers in the United States. The figure is even higher worldwide—93 percent. The chemical industry is also a primary user of potash resources. 

Good organic lawn maintenance is the secret to having an attractive lawn without using synthetic chemicals. If you select the right mix of grass species for your area and maintain soil fertility and organic matter content, you ll have few problems with insects and diseases. 

The light fractions of petroleum (gases from methane to butane) are valuable raw materials for the chemical industry from which products such as solvents, liquid motor fuel, alcohol, synthetic rubber, fertilizers, artificial fiber and other products of organic synthesis are made. Therefore, it is necessary to reduce the loss of light fractions during petroleum processing. Thus, all hydrocarbons derivable from petroleum need to be preserved for subsequent processing.
