Artificial fertilisers are plant nutrients produced through chemical processes to nurture soil and foster plant growth. Artificial fertilisers mainly consist of plant macronutrients such as Nitrogen, Potassium, Phosphorus and Sulphur, but lack other essential substances (micronutrients). Artificial fertiliser are able to improve the chemical properties of soils, but as they contain no organic substances, they are not able to counter the loss of organic substance through harvesting, which is important for soil structure. On the other hand, organic fertilisers produced out of biodegradable waste – such as e.g. kitchen residues, manure and other organic waste – are complete fertilisers that are able to improve both physical and chemical properties of the soil, and that are normally more balanced in their composition, containing macro- and micronutrients.
