Garden compost, leaf mold and manure will all open the soil up and create more minute channels through which water can escape. For hardpan problems, a shovel may be the best solution. Conversely, sands provide easier passage or transmission of water through the profile. Clay has the greatest ability of mineral materials in the soil to absorb water because of its tremendous surface area.
Clay is often reddish in color, water usually is absorbed into clay slowly, it has a tendency to dry slowly, to clump together and not want to break apart , and to stick like mad to shoes and gardening implements. It will also tend to crust over and crack when it gets dry. If water remains in the hole after 12 hours in total, the drainage in your yard is poor.
A hole that drains within three hours is an indicator of good drainage, and if the hole drains within 3 to 9 hours, most landscape plants should grow in your yard. Soil is generally composed of 50 percent solid material and 50 percent space. About 90 percent of the solid portion of soil is composed of tiny bits of rock and minerals. These solid particles range in size from fine clay to mid-range silt to relatively large, coarse sand.
All soils contain mineral particles, organic matter, water and air. The particles that make up soil are categorized into three groups by size — sand, silt, and clay.

Key concepts Absorption Paper Water Molecules Introduction We all know that washing hands throughout the day can help keep colds and flu at bay. Materials Five or more identical paper towels—preferably the type in public restrooms In case you would like to test different types of paper towels, choose at least five identical towels of each type.
Do not worry about wasting a few towels—this activity might help save paper in the long run! Water Place to hang a paper towel to drip Kitchen scale, one-gram precision or better Paper and pen or pencil for recording weights A workspace that can get a little wet Scissors to make towels smaller for small hands optional Preparation Assemble all of your materials at your workspace. Procedure Unfold the first paper towel if you have the prefolded type.
Wet it thoroughly and hang it so all of the excess water drips out. When the towel no longer drips, weigh it on a kitchen scale. You can heap up the towel on the scale rather than neatly folding it. Record the mass on a piece of paper. Fold an identical paper towel in three if it was not already prefolded and fold it one more time so six layers of towel are on top of one another.
Wet it thoroughly and hang it—still folded—so all of the excess water drips out. Do you think this folded paper towel holds more, less or just as much water as the unfolded paper towel? When the folded towel stops dripping, weigh it on a kitchen scale. Do not unfold it; place it on the scale then read and record its mass.
Paper towels are permeable and porous, meaning that they contain small spaces that both liquid and air may pass through. Of course, the U. But as with all things Costco, you get a lot for your money.
If a towel is thicker, it has more fibers to absorb water with! The fibers in tissues and paper towels are made of cellulose molecules—big molecules that consist of lots of tiny sugar molecules chained together. With a thicker towel, you get more fibers that can absorb more water. In fact, Kenaf was grown in Egypt over years ago and is a close relative to cotton and okra. Cotton can absorb about 25 times its weight in water. Chemists refer to substances like cotton as hydrophilic, which means that they attract water molecules.
The strength of the long nylon molecule made it a great replacement for silk, which had a similar feel and texture.
Darker colors tend to absorb more energy from the sun than objects with lighter colors. Someone wearing a white T-shirt in the summer will find that he is cooler than someone wearing a black or dark-colored shirt. This is true of all materials which have dark colors.
