    en.wikipedia.org/wiki/Plant_nutrition

    Like nitrogen, phosphorus is involved with many vital plant processes. Within a plant, it is present mainly as a structural component of the nucleic acids : deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), as well as a constituent of fatty phospholipids , that are important in membrane development and function.

  3. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nitrogen is the most critical element obtained by plants from the soil, to the exception of moist tropical forests where phosphorus is the limiting soil nutrient, [36] and nitrogen deficiency often limits plant growth. [37] Plants can use nitrogen as either the ammonium cation (NH 4 +) or the anion nitrate (NO 3 −).

    Nitrogen (N), phosphorus (P), and potassium (K) are the key macronutrients required by plants for their growth. When you see a fertilizer bag with numbers on it, stating something along the lines ...

  5. Fertilizer - Wikipedia

    en.wikipedia.org/wiki/Fertilizer

    Although nitrogen makes up most of the atmosphere, it is in a form that is unavailable to plants. Nitrogen is the most important fertilizer since nitrogen is present in proteins (amide bonds between amino acids), DNA (puric and pyrimidic bases), and other components (e.g., tetrapyrrolic heme in chlorophyll). To be nutritious to plants, nitrogen ...

  6. Phosphorus - Wikipedia

    en.wikipedia.org/wiki/Phosphorus

    Phosphorus is an essential plant nutrient (the most often limiting nutrient, after nitrogen), [112] and the bulk of all phosphorus production is in concentrated phosphoric acids for agriculture fertilisers, containing as much as 70% to 75% P 2 O 5. That led to large increase in phosphate (PO 4 3−) production in the second half of the 20th ...

  7. Phosphorus deficiency - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_deficiency

    In plants, phosphorus (P) is considered second to nitrogen as the most essential nutrient to ensure health and function. Phosphorus is used by plants in numerous processes such as photophosphorylation, genetic transfer, the transportation of nutrients, and phospholipid cell membranes. [2]
