Dry sand weighs approximately 100 pounds per cubic foot. Wetted to achieve compaction, this sand could easily contain 10% moisture by weight, or 10 pounds of water per cubic foot of sand.
Hope that helps...
Sand lacks the ability to retain moisture needed for seed growth.
your question is stated wrong! it is should be why does LOAM retain more water than clay and sand.
The maximum bulking of sand is in 13% to 14% moisture content. It's likely to be 13.8% moisture content.
Yes, peat is permeable.Specifically, permeability refers to the ability of water to pass through such materials as silt, sand and clay. The rate is fastest with sand, which drains easily and does not retain moisture. Drainage is slower and retention is higher with clay, peat and silt.
They are cheap and they retain sand.
To retain the plants moisture.
No. Sand and sugar make a mixture as they retain their individual properties.
Most gardeners prefer cedar mulch when wishing to retain moisture.
Cactuses have a waxy coating to help them retain water, and they have spines to keep others from taking their water.
It helps retain some moisture
Bulking of sand means increase in it's volume due to presence of surface moisture . The volume increases with increase in moisture content . The volume may increase up to 20 to 40% when moisture content is 5 to 10 %.Due to moisture in each particle of sand, sand gets a coating of water due to surface tension which keeps the particles apart. This causes an increment in volume of sand known as Bulking.
It is the white fuzz underneath the leaves that help it retain moisture.
