Soils are a key component of the interface between the biosphere (life) and the geosphere (land). Soils support life.“Our soils support 95 percent of all food production, and by 2060, our soils will be asked to give us as much food as we have consumed in the last 500 years,” according to Living Soil by The Soil Health Institute.
Much of the food that people eat is produced as crops grown from seeds. What does it take for a seed to grow? How does a seed start to grow? What changes occur as it grows?
Understanding the growth of seeds can help us understand food production, which is basic to understanding the issue of hunger in the world.
