When soil becomes compacted the pore-space between the soil particles is reduced or removed entirely.
Smaller (or no) pore spaces means that oxygen levels in the soil are decreased - almost 80% of a plants oxygen is obtained through exchange in the roots.
Smaller (or no) pore spaces in the soil results in saturated or waterlogged soil, this in turn exacerbates the low oxygen levels by forcing even more air from the soil.
The combination of low oxygen levels in the soil as well as the possibility of waterlogged soils results in the root system of the plant becoming compromised. Once the roots or root hairs are damaged the plant is not able to absorb water, nutrients or oxygen.
General symptoms include wilting of the plant (as the root system is damaged and cannot absorb water), yellowing or basal leaves as the root membranes become damaged and osmosis cannot occur.
compost is just decomposed food put into soil. the food breaks down, allowing all of its minerals to sink into the soil. over time, the soil becomes saturated with the mineral, allowing plants to thrive on it. all plants need the minerals and nutrients provided by the concept of composting.
A soil is at permanent wilting point when a plant can no longer extract water from it, even when soil is fully saturated. This occurs when soil water tension becomes so high that it is held too tightly by soil particles for plants to access. At this point, plants wilt and may eventually die due to lack of water.
Saturated or compacted, preventing water infiltration, leading to excess water running off.
Water infiltration increases during periods of heavy rainfall, as the soil becomes saturated and can no longer absorb additional water. It also rises when the ground is frozen or compacted, as these conditions limit the soil’s capacity to absorb water. Additionally, practices like mulching or planting vegetation can enhance infiltration by improving soil structure and reducing surface runoff.
When soil becomes more liquid, it becomes saturated with water and can lead to problems like waterlogging and reduced aeration for plant roots. This condition can hinder plant growth and cause nutrient leaching.
It depends on the variety of plant. However, most plants would struggle with soil that was so compacted that water couldn't easily reach their roots.
Yes, bagged soil can go bad over time if it becomes contaminated with pathogens, loses nutrients, or becomes compacted. It is important to store bagged soil properly and use it within a reasonable timeframe to ensure its quality.
Another name for saturated soil could be soil liquefaction.
This is the zone nearest the surface. This is the zone through which water passes as it makes its way downwards. The soil or rock here is never saturated. This zone does, however, provide the water used by plants growing in the soil.

the porosity is 50%
When soil becomes more liquid, it is called soil liquefaction. This occurs when water-saturated soil loses strength and stiffness, behaving more like a liquid than a solid. It can lead to ground instability and cause buildings to sink or tilt.
