From slimy worms to growing plants, learn all about soil and the things that depend on it in five easy-to-read chapters. This book captivates young readers through vibrant, full-color photographs. Zoom in even deeper with a key stats section and bolded glossary words.

With water becoming an increasingly scarce resource in Australia, this video clip explores soil crack dynamics and how understanding them may provide better strategies for water conservation and crop irrigation.

An introduction to different kinds of rocks and soils describing their characteristics, how they are formed, their location, and uses.

This program looks at the way soils can vary even within a small area of a forest. A well-developed podzol is examined in detail, with samples taken from the center of each horizon and then analyzed for organic content, soil acidity, mineral content, and particle size distribution. The measurements and analyses demonstrate why three soil profiles can be so very different in closely contiguous areas, with the same underlying sand, the same climate,...

"We’re working on various applications of spectroscopy in low resource settings. So, what that means is using optical technology to really understand the chemical makeup of different materials,” said Matt Keller, a research scientist at Intellectual Ventures Laboratory.

Just as humans cannot grow without our supportive microbiome, neither can plants. Plant roots, bacterial sheathes, and long filaments of fungus all function together to support the plant's growth, enhancing the uptake of water and nutrients and improving soil structure. But what happens to this crucial symbiosis when you add unnecessary fertilizers?

Soil may be the most important geologic resource on the planet. Discover how geologists classify soils, focusing on the concept of soil horizons, which are distinct layers that often vary in composition, color, and texture. Analyze how this cross section, which signals soil fertility, differs depending on the type of biome. Learn how soils form and how easily they are destroyed by erosion.

This book examines the composition of soil, discussing nutrients, organic matter, and the different types of soil.

Discusses the different types of soil, its properties, erosion, pollution, and how humans can protect soil.
