Sand absorbs water less effectively than humus due to its larger particle size and greater porosity, which allow water to drain quickly rather than being retained. In contrast, humus, composed of decomposed organic matter, has a fine texture and high water retention capacity, enabling it to hold moisture more effectively. Additionally, humus forms a gel-like substance when wet, which enhances its ability to absorb and retain water compared to the coarse structure of sand.

What are the main factors used to classify soils?
Humus,sand,clay,and water
Why is the soil sandy in the desert?
Desert soils contain a high percentage of sand and are low in organic material. This happens in areas where there are few plants that would provide the decayed leaves and other dead organic material called humus. Humus is rich in nutrients and is better able to hold water than sand.
How much water sand absorb?

Can sand hold the water better than the clay?
Clay is very made up of very small tightly fitting particles and is non-porous and does not absorb water, which is why it is used to make pottery and ceramics. Sand is larger particles and can absorb large quantities of water.
Which is heavier gravel clay sand humus?
First, the lightest soil component is clay. The, there's sand then humus then finally gravel.
How much sand clay gravel and humus does it take to make soil?
25%-sand 255-clay 25%-gravel 25%-humus
Does sand absorb oil the best?
Sand does not 'absorb' oil as it is none absorbant, however oil will coat the particles of sand thereby giving the impression of absorbing oil as this is what it appears to do when the sand is dry
Does sand contain alot of humus?
No, sand typically contains very little humus. Humus is the organic component of soil formed from decomposed plant and animal material, and it is more commonly found in loamy or clay soils, which retain moisture and nutrients better than sandy soils. Sand is primarily composed of mineral particles and has a coarse texture that does not support significant organic matter accumulation.
Is humus mixture of sand and clay?
yes
What is the type of soil that contains a mixture of sand silt clay and humus?
As Loam soil has almost equal proportions of sand, silt & clay the bacterial activity is very high. Hence bacterial activity is highly predominant in loam soil. So humus content may be high in loamy soil than clay which has high organic content but poor aeration due to which bacterial activity is low.
What is that sand called that you put in water and it doesn't get wet?
That sand is called hydrophobic sand. It is coated with a substance that repels water so that it does not absorb moisture when placed in water.
What items are found naturally in soil?
Sand and humus.
