Factors affecting the Crushability of Decomposed Granite Soil

Soil Fertility of Decomposed Granite Cut Slopes and Adjacent Vegetated Soils

In Thoreau's time, people were already planting trees to restore landscapes. Throughout this century, public and private organizations as well as countless landowners have worked to restore plant communities to sites that have been disturbed by natural disasters, and by human activities such as mining, road construction, clear cutting, and agriculture. Over the last 20 years, restoration ecolog...

The Stress-Strain-Strength Behaviour of a Completely Decomposed Granite Soil Using a New Advanced True Triaxial Testing System

Completely decomposed granite (CDG) soil is the most common type of soils found in more than 90% of the land area in Hong Kong. The measurement of the stress-strain-strength behaviour of the CDG soil is very important for deformation and stability analysis of slopes, retaining walls, excavations, deep and shallow foundations related to the CDG soil ground. As most of these geotechnical structur...

1 Soil Factors Affecting Nutrient Bioavailability

The soil supports plants, is the physical determinant of root growth and extent, and is the main reservoir for plant-available water and nutrients. Therefore, the soil controls the availability of most essential plant nutrients. It regulates availability by means of biophysiochemical processes, which are functions of soil and plant properties. This chapter introduces the concept of soil nutrien...
