What are the elements that plants need to grow?

Did you know that there are over 18 elements plants need in order to grow? Macronutrients plants need are those elements that your plants will use lots of, whereas micronutrients are used in small amounts to grow. We'll start with the big three macronutrients: Carbon (C), Hydrogen (H), and Oxygen (O). These may seem like a no-brainer, but these elements are essential to all life on earth, especially planets. Do they look familiar? That's because plants get these elements from the air (CO2) and from water (H2O), and these two compounds create the basis for sugars and starches your plants need. These will give strength to and build cellular walls, leaves, and stems. The second set of macronutrients are the three we're all aware of: Nitrogen (N), Phosphorus (P), and Potassium (K). These elements are what help your plant break down elements it needs to survive, help turn light and water into food for your plants, and help build the strength of your plants. Specifically, (N) is found in chlorophyll, amino, and nucleic acids, and in proteins and enzymes. (P) helps cell membranes and has a big role in the ATP (energy system) of a plant. (K), on the other hand, is heavily involved in photosynthesis and resilience especially when it comes to droughts. The last set of macronutrients your plants need are Calcium (Ca), Magnesium (Mg), and Sulfur (S). While not used as much as their macronutrient counterparts, these elements are vital in assuring your plant's survival. (Ca), for example, helps strengthen cell walls and helps deliver nutrients when your plants are stressed. (Mg) is vital in chlorophyll production, function, and breaking down enzymes, whereas (S) is important in creating chlorophyll and creating proteins for your plant.

What are the elements that help plants grow?

What are the two forms of nitrogen in soil?

They fix atmospheric nitrogen into the soil in the form of nitrites (NO 2 ), and nitrates (NO 3 ). These heterotrophic organisms, occurring in the soil convert nitrogen gas (N 2) to anionic forms such as nitrates (NO 3) or nitrite (NO 2– ), or a reduced cationic form such as NH 4+ (ammonium).

How do nitrogenous compounds enter plants?

These nitrogenous compounds enter plants as nutrients through the roots and are assimilated as organic nitrogen. The plants, in turn, provide organic nitrogen to heterotrophic organisms. The other elements are absorbed from the soil, such as phosphorus (P) as phosphate (PO 4 ), and sulphur (S) mainly as sulphate (SO 4).

Why is chlorine needed in photosynthesis?

It is required for cell division in roots and leaves. It is needed to perform water-splitting reaction in photosynthesis, which evolves oxygen.

The important functions of it are as follows: (i) Nitrogen is an essential constituent of proteins and is present in many other compounds of great physiological importance in plant metabolism e.g. nucleotides, phosphatides, alkaloids, enzymes, hormones, vitamins, etc. It is, therefore, a basic constituent of “life.”.

What is the function of sulphur in plants?

One of the main functions of sulphur in proteins or polypeptides is the formation of disulphide bonds between polypeptide chains.

Why is the vegetative portion of a plant more succulent?

Less carbohydrate is thus deposited in the vegetative portion, more protoplasm is formed, and, because protoplasm is highly hydrated, a more succulent plant results. Excessive supply of nitrogen develops excessive succulence which results harmful effects in some crops like weakening of fibre in case of cotton, lodging in case of grain crops etc.
