Phosphorus  - Phosphorus is one of the six basic chemicals of life.  Six chemicals - carbon (C), hydrogen (H), oxygen (O),  nitrogen (N), sulfur (S) and phosphorus (P) - make up about 98 percent of the weight of people and trees.
    Phosphorus is absorbed in different forms. E.g., Phosphates.  The first part of photosynthesis involves phosphorus to form a substance called ATP-Adenosine Triphosphate.  ATP holds energy in its bonds.  It is the international currency.  It is like liquid assets.  ATP supplies the energy to make processes proceed.  Phosphorus is a part of DNA and enzymes.  ATP is involved in making lipids [L] and carbohydrates [CHO].  ATP pays the bills to make these essential substances, and many more!  This is why trees require phosphorus.  And, this is why mycorrhizae are important.  They are very active in absorbing phosphates.  Trees do not absorb phosphorus, they absorb phosphates.
