context_page_description: A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply one or more plant nutrients essential to the growth of plants. Many sources of fertilizer exist, both natural and industrially produced.
  In the later half of the 20th century, increased use of nitrogen fertilizers have been a crucial component of the increased productivity of conventional food systems. According to the IPCC Special Report on Climate Change and Land, these practices are key drivers of global warming.
context_section_description: Foliar fertilizers are applied directly to leaves. This method is almost invariably used to apply water-soluble straight nitrogen fertilizers and used especially for high-value crops such as fruits.
