Why is my soil so loose?
The most common reason for instability is composition - the proper balance of mineral pieces, matter, air and water. For instance, a clay soil, with the correct moisture content, can be an incredibly stable soil, almost to the point of concrete. (Bricks can be made out of clay).
What is loose soil in civil engineering?
Loose soil structure has large volume of voids, hence they have high void ratio and high permeability but they are unstable. When loose soils subjected to vibrations their particles move and acquire a more stable position and form a denser state.
Which soil is best for growing plants?

peatSoil containing peat or expansive clays are the worst kinds to build on, and a soil engineer would probably suggest you remove the soil from the site before building.
What are the 4 types of soil?
OSHA classifies soils into four categories: Solid Rock, Type A, Type B, and Type C. Solid Rock is the most stable, and Type C soil is the least stable. Soils are typed not only by how cohesive they are, but also by the conditions in which they are found.
Which foundation is best for weak soil?
1. Mat Foundation. A mat foundation takes full advantage of the surface area where the building will be erected, essentially using the basement as the entire load-bearing foundation. Mat foundations are often used when the soil is loose, weak, and requires the weight to be distributed evenly.
How can I make my loose soil more compact?

What is loamy soil?
Jupiterimages/liquidlibrary/Getty Images. Loamy soil is a medium-textured soil that contains several different soil particles. It is preferred by gardeners as it provides an ideal environment for many types of plants to grow in. It tends to be soft and crumbly when dry and sticky and moldable when moist.
What is the smallest type of soil?
Soil is composed of various sizes of tiny particles and organic matter that are categorized as sand, silt or clay. Clay, the smallest type of soil particle, tends to compress easily, which makes for poor drainage and allows little to no air to penetrate the soil.
What is silt loam made of?
Finally, silt loam has a small amount of sand and clay but is mostly composed of silt particles.
What is the difference between loam and clay?
Loamy soils are divided into categories, depending on its content of sand, silt and clay particles. Loamy sands, for example, consist of 70 to 90 percent sand, 30 percent or less silt and 0 to 15 percent clay. This type of loamy soil is loose like sand. Clay loam consists of a more even distribution of the three types of soil yet feels like it has more clay. It is sticky when wet and can be formed easily into a ball. Finally, silt loam has a small amount of sand and clay but is mostly composed of silt particles. The texture is lumpy, but the lumps are easily crushed into a soft powder.
What is the largest part of soil?

How long does it take to mix sand and water?
Put on the lid and shake the jar vigorously to thoroughly blend the mixture, and then set it aside. After six to 10 hours, check the jar—the soil and water will have separated and settled into layers. Sand (the heaviest) will be at the bottom, silt will be in the middle, and clay will be on top.
What are the components of soil?
SOIL COMPONENTS. Types of soil are classified by the amount of sand, clay, and silt they contain. The composition of these different sized particles determines how well the soil will absorb and retain water. Each component brings something to mix, and loamy soil contains a mixture of all three. Sand particles are the largest of the three.

It can take three to six years to obtain optimal loamy soil. Implement one or more of the following methods to get your soil in top shape, and keep it that way: Apply a two-inch layer of organic matter to the surface of your garden in late fall, after harvest is over and the plants have died.
What is the best way to make soil loamy?
No matter what imbalance your soil currently has, the key to achieving a fertile loamy soil is to amend it with organic matter. This includes garden compost; peat moss; composted horse, goat, chicken, or cow manure; dried leaves or grass clippings; or shredded tree bark.
What soil holds a ball shape?
Sandy soil will not hold a ball shape—it feels coarse to the touch, and it will sift through your fingers as you open your hand. Clay soil will form a firm ball that will retain its shape after you open your hand. If you set the ball aside and let it dry, it will become rock-hard and difficult to break.
What happens if your soil is too hard?
This same concept applies to your plants. If the soil is too hard (or congested), there are simply too many roadblocks that prevent your roots from soaking up all the nutrients your soil can offer.

Why are my plants leaves turning purple?
Low Nitrogen: If your plant leaves (low on the plant itself) are discoloring and falling off the soil is likely low in Nitrogen. Adding compost to the soil is an organic way to fix this issue. Low Phosphorous: Do your plants look purple? They are likely low in phosphorous.
Is soil crumbly or hard?
The crumble: Is your soil crumbly like a good coffee cake or dry, hard and cracked? The soil should be crumbly. If it’s dry and cracked, water will run off and not absorb into the soil like it should. Also, not enough water will make it to the root system and allow the roots to grow down in all that hard soil. So, crumbly good. Dry and cracked bad. How do you deal with this problem? Add organic matter and add it often. Also, do not compact the soil.
What is a porous soil?
What Does Porous Soil Mean? Porous soil types include coarse particles that leave large gaps known as pores. The spaces between the particles of clay, silt and sand that make up the structure of soil hold air and water. The size and number of pores in a soil affects how much water it can hold and how quickly water drains out of the soil.
What is soil in agriculture?
Penn State College of Agricultural Sciences describes soil as the thin layer of natural materials, mostly broken rocks, minerals and decayed and decaying organic material, that covers the Earth. When soil contains optimum amounts of air and water, soil provides support and nutrients for plants to grow.
What is the role of clay in soil?
Large pore spaces allow water to drain through the soil quickly, and porous soil often holds fewer nutrients than other soils. Particles of clay and organic matter help hold nutrients in the soil. The ratio of organic matter and particles of clay determines the fertility of soil.
How does porosity affect irrigation?
Porosity and permeability affect how irrigation water moves through the soil. In sandy soils with large pore spaces, water is heavily influenced by gravity. The porosity of sand and other coarse soils tends to let water move straight down from the surface. In clay soils with small pore spaces, water moves slowly and spreads outward from where it is applied due to capillary action.
What are the factors that determine the fertility of soil?
Particles of clay and organic matter help hold nutrients in the soil. The ratio of organic matter and particles of clay determines the fertility of soil.
How to water plants in a porous soil?
The best way to water plants growing in a porous soil is to water more frequently with smaller amounts of water. The fast-drainage characteristics of porous soils allow nutrients to leach out of the soil quickly, limiting the effectiveness of fertilizers on porous soil. You can till compost or another form of organic matter into porous soil to improve its water holding capacity and fertility.
What are the components of soil?
The four components are air, water, mineral particles and organic material. An ideal soil contains about 50 percent air and water held within the pore spaces between the organic material and mineral particles. Organic material, living and remnants of living things, makes up one to five percent of the perfect soil while mineral particles, ...

What happens if you submerge soil for a long time?
What happens if a red or yellow soil is submerged for an extended period of time? The aerobic bacteria normally present in the soil eventually run out of oxygen and go dormant, leaving the field open for anaerobic bacteria. Anaerobic bacteria use up a great deal of iron in their metabolism process, altering ferric iron to ferrous iron in the process. Ferrous iron has no color. As the anaerobic bacteria feast and multiply, the color disappears from the soil. Meanwhile, with water displacing the oxygen in the soil, the iron compounds that form the mineral element of the soil stop oxidizing and producing rust colors.
Why is pale yellow soil leached?
As also mentioned with reds, pale yellow soils have been leached and would benefit from the addition of some organic matter to retain nutrients. Note that intermediate tan colors are formed when organic matter is added to soils containing iron oxide.
What happens when soil is dark?
Also, very dark soils generally contain sodium, as sodium causes organic matter and humus to disperse more evenly throughout the soil.
What does black soil mean?
But truly black soils can also indicate trouble in the form of complete saturation and high levels of anaerobic bacteria. Fortunately, there is no mistaking this type of black with the rich black of healthy soils. Unhealthy black soils look and smell disgusting—they are basically vats of anaerobic rot in the making.
Why is my soil orange?
Orange soils are seen when iron has been precipitated out of water. Thus, an orange color suggests that the soil is periodically waterlogged. Or if your soil was previously some other color and has suddenly turned orange for the first time, it could indicate that the problem is with excess iron in your water supply.
What does it mean when soil is grayish?
Grayish soils, therefore, are found in areas with high levels of both moisture and iron. If a gray soil has a bluish or greenish cast, that may indicate the presence of sulfur. A mottled gray, as opposed to a uniform gray or blue-gray, suggests that the soil is waterlogged at times and fairly dry at other times.
What are the factors that affect the color of soil?
Some of the factors that alter the color of soil include: Aeration. Saturation. Mineral content. Degree of weathering. Presence of organic matter and humus. All of these considerations are very important to the health of your garden plants.
How to fix a soil that is too slow to drain?
Digging organic matter (like compost or shredded leaves) into your existing soil is one of the best things you can do to improve soil drainage. This simple fix works for almost any soil that drains too fast or slowly. For an unplanted bed, spread 3-4 inches of your organic matter across the surface of the soil and work it into the top 8-12 inches (a garden tiller or pitchfork will do the job). For a bed that is already planted, add a couple of inches of compost to the soil surface each year and over time, nature will do the mixing.
What is the process of water moving down the soil?
When it rains or you irrigate your garden , these pore spaces fill with water. As the water moves downward through the soil, it’s replaced by air. This movement is referred to as soil drainage, and how fast it happens is what’s important.
How to tell if soil is well draining?
Just dig a hole about 12-18 inches wide and 12-18 inches deep (it doesn’t have to be exact). Fill the hole with water. After it drains completely, refill it with water and note how long it takes for the water level to drop.
Why is it important to have well-drained soil?
This movement is referred to as soil drainage, and how fast it happens is what’s important. A well-drained soil retains water long enough for roots to absorb what the plant needs, and dries out sufficiently between rains or waterings so that roots can take up oxygen and don't rot from too much moisture.
Why does my clay soil rot?
But in heavy clay soil, you may have the opposite problem, where water takes a long time to drain, causing roots to rot from a lack of air. If your garden soil suffers from either extreme, improving its drainage will go a long way toward creating a healthy, successful garden. scooping soil with hand trowel.
What do you want in soil?
What you want is soil that supplies both air and water to plant roots in about equal proportions . If you have coarse, sandy soil, you may notice that water drains quickly through it so your plants dry out and wilt sooner.
How to check how well your soil drains?
Just dig a hole about 12-18 inches wide and 12-18 inches deep (it doesn’t have to be exact). Fill the hole with water. After it drains completely, refill it with water and note how long it takes for the water level to drop. In soil with good drainage, the level should drop about an inch per hour. Slower or faster than that could lead to problems, but there are several ways you can improve your soil’s drainage.
Soil Components
A Balancing Act
- By blending all three soil components, loamy soil has the ability to retain enough moisture (as well as an abundance of nutrients) to keep plants healthy but also allow the excess to drain away. That balance is key to preventing standing water conditions, which can smother a plant’s roots. Indeed, loamy soil offers the best of all worlds, and its c...
Determining Soil Content
- Achieving loamy soil can be a bit of a guessing game—you need to know what type of soil you currently have in order to know what you’re missing. One way to determine soil content is to collect a soil sample from your garden and take it to your County Extension Office(a branch of the USDA), for testing. Many gardeners, however, learn to estimate the content of their soil by feel. T…
Creating Loamy Soil
- While it might seem as though you should be able to balance the components by adding sand to heavy clay soil or clay to sandy soil, it doesn’t work that way. Instead of achieving loam, you’ll end up with something akin to cement, which is very hard to dig and plant. No matter what imbalance your soil currently has, the key to achieving a fertile loamy soil is to amend it with organic matter…
