  • a fertilizer may be a single substance or a composition, and is used to provide nutrients to plants.
  • a major ' breakthrough in the application of fertilizers was the development of nitrogen-based ferti lizer by Justus von Liebig around 1840. Fertilizers, however, can lead to soil acidification and. destabilizaiiou. of nutrient balance in soil, including depletion of minerals and enrichment of salt and heavy metals.
  • excessive fertilizer use can lead to alteration of soil fauna as well, as contaminate surface water and ground water. Further, unhealthful substances such as nitrate may become enriched in plants and fruits.
  • Plants generally maintain constant levels of essential mineral nutrients in order to attain optimal growth and development, even though such nutrients are in many soils present in low concentration or accessibility.
  • plants have evolved adaptive responses, which enable them to grow also on a soil with limited amounts of one or more nutrients.
  • Many nutrients have for Instance low solubility or ar distributed in an irregular manner i soil.
