How do you describe soil structure?
Soil structure is determined by how individual soil granules clump or bind together and aggregate, and therefore, the arrangement of soil pores between them. Soil structure has a major influence on water and air movement, biological activity, root growth and seedling emergence.
What state of matter is soil?
Soil is an aggregate mix of compounds both organic and inorganic, and despite its plastic or powdery texture usually is considered to be in the solid state, although it does have some liquid or gaseous components.
What is the main soil type of the woodlands?
A site's soil characteristics have a major impact on the type and quality of trees produced. In general, soil type is classified by its texture, or size of soil particles, porosity and fertility. Further classification of a soil's quality is determined by measuring its chemical and biological indicators. A soil's infiltration rate and aggregate structure and stability help determine the soil's water-holding capacity, while its organic matter will indicate the soil's overall fertility level. Generally, fine-textured (clay) and medium-textured soils have a greater nutrient content than course or sandy soils. The soil's porosity, or measure of the spaces between particles, and aggregate structure will determine how quickly water drains from the site. Clay soils can hold more water, but absorb the water more slowly because of its low saturation point. Soils with a high percentage of silt have the most favorable texture for moisture absorption and drainage. For more information on soil types and to get your soil tested, contact your county UW-Extension office. Soil maps are available from your local U.S. Natural Resources Conservation Service office.
What kind of soil allows water soaks into the ground quickly?
Coarse sand is the best for allowing water to penetrate. The larger the aggregate, the faster the water will pass thru. Sand that does not usually have much biological material in it, tends not to soak up and slow down the filtration process.
What about dry and wet impact value in aggregate test?
OBJECTIVE For determination of the aggregate impact value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm. IS sieve. Aggregate impact value test gives an indication of aggregate’s toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. The test equipment and the test procedure are quite simple and it determines the resistance to impact of stone aggregates simulating field condition. This test can be performed even at construction site or at stone quary, as the apparatus is simple and portable. Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate. Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact values are numerically similar within close limits. For deciding the suitability of soft aggregates in base course construction, aggregate impact test is commonly used. A modified impact test is also often carried out in the case of soft aggregates to find the wet impact value after soaking the test sample in water. Maximum allowable aggregate impact value of aggregate in different types of pavement material / layers.
What soil constituent responsible for high aggregate stability of forest soil?

What is the weight of 1m3 of hard core aggregate?
It really depends on the composition of the soil. Soil with a lot of clay will weigh more than soil with a lot of sand.
What is plant media?
The term "plant media" refers to the soil, aggregate, or substrate a plant is growing or grown in.
Does rock come from soil?
No, rock is an aggregate (group) of minerals. Soil has rather small ground rock pieces but also has organic material as well. If it has a lot of organic materials, it is called top soil. Crops do well in top soil.

What does Continious Mixers Australia offer?
Continuous Mixers Australia specialize in the aggregate and soil stabilization industry. They offer road base water mixing for roads, soil contamination rectification, and roller compacted concrete.
What will happen when Aggregate demand and aggregate supply decrease?
When aggregate demand and aggregate supply both decrease, the result is no change to price. As price increases, aggregate demand decreases, and aggregate supply increases.
How many cubic meter will excavate a backhoe per hour?
The cubic meters of aggregate that a backhaul can excavate in an hour is dependent upon the size of the backhoe. Typically, a backhoe can ask of a 100 cubic meters of aggregate per hour.
