Impact Of Floods On Soils -- ScienceDaily

During the wet season in the U.S. Midwest, upland soils are often under water for days or weeks, causing oxygen depletion, or reducing conditions, which may in turn affect the chemistry of the soil-water system and, consequently, soil aggregation. Loss of soil aggregation impacts agriculture by decreasing soil quality and crop production.

Absorption and Movement of Water in Soil. The movement of water from the soil surface into and through the soil is called water intake. It is the expression of several factors including infiltration and percolation. Infiltration: Infiltration is the term applied to the process of water entry into the soil generally (but not necessarily) through the soil …

Water absorption variability of recycled concrete aggregates

By replacing natural aggregates with recycled aggregates, it could release the pressure on the Belgian market of natural aggregates; (Boehme et al., 2012) Recycled aggregates (RA) have a lower market value than natural aggregates and concrete made with recycled aggregates has a lower density (1-2%) than concrete made with natural aggregates.

Soil Health - Formation of soil aggregates

What are soil aggregates and soil pores? Soil aggregates are clumps of soil particles that are held together by moist clay, organic matter (like roots), gums (from bacteria and fungi) and by fungal hyphae. The aggregates are relatively stable. Aggregates vary in size from about 2 thousandths of a millimetre across, up to about 2 millimetres across.

Absorption of water - Wikipedia

The absorption of water by plants is essential for various metabolic activities. Land plants get their water supply from soil which serves as the source of water and [minerals]. The way in which water from soil enters roots, particularly to the root xylem, is called "mechanism of water absorption".

3 Aggregate Properties - IN.gov

There are aggregate particle voids, and there are voids between aggregate particles. As solid as aggregate may be to the naked eye, most aggregate particles have voids, which are natural pores that are filled with air or water. These voids or pores influence the specific gravity and absorption of the aggregate materials. Figure 3-1.
