A List of Important Chemicals.
Here is a brief list of important chemicals, required by plants. Commercial labeling will usually list them by the abbreviations such as. (N) Nitrogen. (P) Phosphorus. (K) Potash.
There are of course various individual plant foods marketed. Such as. Rose feed. Rhododendron feed etc. Unless you are chemist. I’d plump for the pre-packed solutions.
(N) Nitrogen. This is an element that all living things requires.
(P) Phosphorus. An element that is required by plants. (Keeping these elements to plants) This element will aid the good growth of a plant. Should your plant suddenly develop dark green, or bluish green foliage, and sometimes a reddish impregnated markings. This is a sure sign of a deficiency of (P). (K) Potash. Potassium. This can produce similar foliage changes as (P) However the main purpose of (K) is to produce flowers/seeds etc. (Ca) Calcium. This is required for the binding together of the cell structure of the plant. It also plays a big part in the production of good strong roots. So should your plant start to wilt and look washed out, the lack of calcium might be the problem. However. Over watering or lack of, can fool even the expert at times. (Mg) Magnesium. This chemical plays an important part in plants etc. In simple terms. It acts like an organizer, as it were. Sorting out and putting in place the other chemicals. It is very important in the production of chlorophyl. This is what give the plants that green look. We all know about UV and photosynthesis. Well if there is a lack of Mg, then however much sunlight there is. The system might not work. So if your plant suddenly become anaemic looking, perhaps the Mg is low. (Fe) Iron. This is a bit more technical. As we know. In the human body. Iron is very important to our blood supply and content. Similar within plants. It is used in reactions in which rapid oxidation reductions occur. Plants with an iron deficiency will become chlorotic. (Mn) Manganese. This is required in small amounts. I t is involved in the light reactions of photosynthesis and binds to proteins. Signs of deficiency. Chlorosis and malformation. (B) Boron. An element found in boracic acid. It’s full value is not as yet, scientifically understood..
I do hope this will help others to further their knowledge.
