Introduction: Hello and welcome to our channel where we explore the wonders of nature. In this video, we will be discussing an incredible phenomenon that has been observed in some of the world’s oldest seedlings. After a hundred years, the roots of these plants have grown so extensive and deep that they have the ability to fertilize the soil and even cover a person! This is truly a miracle of nature that we will be exploring today.
Body: Let’s start by talking about the importance of soil fertilization. Soil is essential for the growth and survival of plants. It provides them with vital nutrients, minerals, and water. However, over time, the nutrients in the soil can become depleted, making it difficult for plants to grow. This is where fertilization comes in. Fertilizers are used to replenish the nutrients in the soil, making it more fertile and allowing plants to grow stronger ahealthier. 
Now, let’s take a look at the amazing phenomenon of these hundred-year-old seedlings. As the roots of these plants grow deeper and more extensive over time, they can reach areas of soil that other plants cannot. This allows them to absorb nutrients and minerals that are not accessible to other plants, making them incredibly effective at fertilizing the soil.
In some cases, the roots of these seedlings have grown so large
