Why Do Plants Need Fertilizers?

Plants are also considered as living beings of nature just like humans, animals and other living stock. Just like how we humans need extra vitamin, calcium and other supplements apart from our normal intake of nutrition to stay healthy, plants need fertilizers to grow and stay healthy. In order for the plants to grow, they need a number of chemical elements. Let us find out how fertilizers work.

Important Elements That Plants Need
Plants need carbon, hydrogen and oxygen, which are available in plenty from air and water.
Besides these, they need nitrogen, phosphorous, potassium, sulphur, calcium, magnesium, boron, copper, iron, cobalt, manganese, molybdenum and zinc as add on for their growth.

Nitrogen, phosphorus and potassium are considered as building blocks for cells in the plants as without them the plants cannot grow and will not be in a position to build cells.

How Do Fertilizers Work
In some cases, plants find it difficult to find all the macronutrients from the soil itself
and this hinders with their growth. Nitrogen, phosphorus and potassium are found from the decay of plants that have already died. Nitrogen is found from dead to living plants and is the only source found in the soil. Fertilizers provide all the important elements in a readily available form.

Also when the fertilizers are added to the plants, they have to just synthesize them as opposed to making an effort to break them down into the desired form. As a result the synthesizing is quick and the plants grow faster and better.

Each bag of fertilizer has numbers written on them. These numbers indicate the amount of available nitrogen, phosphorus and potassium in each bag.

So next time if the plants in your garden don’t bear flowers, you know what you are suppose to do.
