Why artificial fertilizer?

It is all chemical-made in a laboratory. Its not like cow manure which is natural.

Artificial fertilizers are those produced by the chemical industry, as opposed to the organic or mineral fertilizers. Not organic as in organic farming, but organic as in carbon-based animal or vegetal organism, like manure.

For instance, the nitrogen in artificial fertilizers used to come from oil, it is now extracted mostly from natural gas and comes in liquid or dry powder/pellet forms, mixed with other substances, mostly phosphorus and phosphates, in different (NPK) ratiOS according to the culture you are growing.

Pure chemical elements are easy to obtain in powder form, so artificial fertilizers also include other macronutrients such as calcium or magnesium, and micronutrients which are other mostly metallic elements, for instance boron, manganese and zinc, which are critical for the well-being of the plants, even though they are needed only in very small quantity.

Artificial fertilizers include only the pure and bare essential elements, whereas these elements make up a minor part of organic fertilizers, where the carbon-based elements represent the major part and serve to form humus, an essential part of the living soil. This is the reason why artificial fertilizers are described as washing out the top-soil and encouraging erosion and pollution of the aquifers and water ways, especially after a hard rain. A soil with no humus to absorb the water will erode quickly. Most American agricultural soil countrywide has lost several feet of top soil over the last century, most of which now lies on the ocean floor.

All forms of artificial fertilizers are prohibited in organic farming, which relies on a sustainable cultivation cycle, or, in the case of intensive organic farming, on external inputs that are supposedly local and as much sustainable as possible.

Agriculture being artificial by definition, it is not always possible to avoid inputs from non-renewable sources, such as calcium mined from mineral deposits, but these are not artificial and therefore tolerated.
