Explain how soil structure affects the physical properties of soil.
Soil structure is the arrangement of soil peds. This arrangement determines the space between soil peds, which determines the porosity of soil.
What is the distinction between soil structure and soil texture?
Soil texture is based on the amount of the different types of soil particles. It differs based on the proportion of sand, silt, and clay present in soil samples. Soil structure, on the other hand, has to do with the pattern of peds in soil. The soil structure determines the amount of space available in the soil and therefore the water absorption of a soil sample.
Explain how plant life is benefited when microorganisms release carbon dioxide into the soil.
When microorganisms release carbon dioxide into the soil, the acidity of water surrounding soil particles is increased. This increase in acidity allows for rock present in soil to be broken down, releasing minerals into the soil. These minerals are then available for use by plant life.
What soil properties are influenced by microorganism activity?
Microorganism activity affects soil acidity and the amount of organic matter in soil. It also affects the nutrient and mineral levels in soil as well as soil structure.
Explain how microorganisms, humus, and soil health are related.
Humus is decayed organic matter in soil. Humus is a result of plant and animal matter being incorporated into soil through the action of soil microorganisms. Humus benefits soil health by providing nutrients for soil life, increasing the porosity of soil, and creating good soil tilth.
