Quizplus · Accepted Answer

Mild weathering of parent material and the addition of organic matter are the primary mechanisms for soil becoming fertile. As the parent material weathers, minerals are broken down into smaller particles, which can provide nutrients for plants. Additionally, organic matter such as plant debris and animal waste can add nutrients and improve soil structure, allowing for better water retention and root development.
