Soil is made up of air, water, mineral particles, organic matter and organisms. It takes thousands of years for rock to develop into soil and hundreds of years for rich organic layers to build up. Keeping soil in place is only the beginning of soil conservation.
In this video, we will review how far we have come and explore what needs to be done to preserve this precious resource. We also will look at how soil affects us and our productivity. How do we continue to maximize the land's output without diminishing the soil's natural capacity?
