How does fertilizer affect the growth of a plant?

Fertilizer affects plant growth by supplementing plant nutrients, which allows plants to grow faster and thicker. However, this applies only if the soil is deficient in nutrients. Fertilizer does not compensate for other growth-inhibiting factors such as lack of water, poor soil preparation and weeds.

In this manner, do plants grow better with fertilizer?

Plants need to be fertilized because most soil does not provide the essential nutrients required for optimum growth. Even if you are lucky enough to start with great garden soil, as your plants grow, they absorb nutrients and leave the soil less fertile. It took nutrients from the soil to build those plant tissues.

Why is fertilizer important for plant growth?

Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. Fertilizers are simply plant nutrients applied to agricultural fields to supplement required elements found naturally in the soil. Fertilizers have been used since the start of agriculture.
