Plant nutrients are essential in order for plants to survive and grow healthy. Therefore it is important that we provide plants with the suitable nutrients so that they can perform at their best. A lack of these vitamins will cause plants not only to become stressed but plants will also become susceptible to insects and disease.
These vitamins/nutrients are found in the soil but because they are in such small amounts, human effort is needed to help make up or supply plants with the right amount of nutrients.
Number of nutrients required by plants
There are sixteen chemical elements that are available for plant growth and development. These elements are divided into two groups. These two groups are non-mineral and mineral.
Non-Mineral Nutrients consist of:
1. Oxygen (O)
2. Carbon (C)
These nutrients are found in the air and water. Plants use these along with the sun’s energy to convert starch and sugars.
Please note that “fertilizer does not plant food”. Fertilizers are plant nutrients. For a clearer understanding, it can be compared to humans taking vitamins and supplements. Vitamins are not considered to be food but nutrients for our bodies and so it is the same with plants.
As discussed earlier in this chapter, soil also contains plant nutrients that are known as mineral nutrients but they are in such small amounts that there is not enough to supply and support plant growth. These mineral nutrients are further divided into two groups which are:
Macro-nutrients are broken down into two main group, primary and secondary nutrients. The primary nutrients are nitrogen(N), phosphorus(P) and potassium(K). These three primary nutrients are the first three numbers on the fertilizer bag. These numbers tell us the amount of these primary nutrients that the fertilizer contains.
The second nutrients are Calcium (Ca), Magnesium (g) and Sulfur (s). Because these nutrients are not used up quickly in the soil there is often enough present in the soil.
Micronutrients are also required by plants, but plants only need these elements in small amounts. Micro-nutrients consist of chloride ( Cl), iron (Fe), manganese (Mn), boron (B), zinc (Zn), molybdenum (Mo).
Nitrogen is needed by plants to help plants green up. Chlorophyll is the green pigment in plants that is responsible for photosynthesis. Nitrogen also helps plant with their growth and also increases fruit and seed production.
Phosphorus encourages flower bloom and root stimulation, helping in the formation of all oils, starches and so on. It also helps plants to stand up to stress, improves the quality of grains, vegetables, and fruits needed for seed formation, helps mature roots and helps in cell division.
Is needed for fruit formation, it increases disease resistance, brakes down and transports starches, helps in the building of protein and increases the quality of seeds.
Is important for plant cell structure, for stimulating microbial activity, for aiding in photosynthesis and strengthening plant cell walls.
Is important because it aids in photosynthesis, helps plants to mature much better, helps to activate plant enzymes and increases the use of iron in plants.
Improves root growth and seed production, helps develop enzymes and vitamins, aids in chlorophyll formation and helps to promote protein.
Aids in seeds and fruit development, aids in the transportation of sugar, aids in seed and cell wall formation and helps to regulate other plant nutrients.
Aids in maturity and helps plant metabolism.
Aids in root metabolism helps with photosynthesis, helps plants in their growth and helps chlorophyll production.
Aids in the formation of chlorophyll and helps with plant cell division.
Aids chlorophyll in plants and helps to break down carbohydrates.
Helps to form enzymes in plants and converting inorganic to organic for plant use.
Aids in seed formation helps plant growth hormones and aids in the transformation of carbohydrates.
More on plants
Plants are living organisms and they must be taken care of if we desire for them to look and perform at their best. So let us do our part to ensure that they grow happy and healthy.
When using fertilizers always remember to follow direction because the label is law. So many times persons have ignored directions and applied fertilizers according to how they thought it should be done and have done more harm than good. So let us follow directions and keep our plants in tip-top shape.
