Soil Plants

Soil is actually composed of several materials. About 50% of what we call soil is solid material, and the remainder is actually open spaces between the particles, which allows air and moisture to penetrate into the soil to reach the roots of plants. The solid portion of soil contains tiny particles of various minerals and organic materials. The minerals come from rocks, which are weathered and broken down by the action of wind and rain over many years, and the organic material comes from decaying plants.
