What is compacted soil?
Compacted soil is a big enough and common enough problem to warrant a closer look. "Compacted" is a term applied to soil which, deprived of proper aeration (perhaps due to heavy foot traffic, among other factors), suffers from excessive water runoff and poor conditions for plant rooting.
What is humus in soil?
Humus is organic matter partly or wholly decomposed. When the decomposition is hastened by human intervention in order to use it as a soil amendment, it is virtually synonymous with " compost .". A generous admixture of this organic matter to soil can help make it more friable.

How to balance organic matter in soil?
The way to create the right balance is to add organic matter — such as compost, grass clippings, dried leaves, or composted manure — which will break down over time, add nutrients to your soil, attract worms and microorganisms, create vital air pockets, and help your soil retain moisture.
Why is silt important for microorganisms?
This creates pockets of air between the grains — necessary for worms and microorganisms to flourish — and improves drainage as water flows easily through them . Silt, made from quartz and feldspar, is slippery when wet, which makes it home to many microorganisms and decaying organic matter (humus).
What is clay made of?
Clay is formed from silicate rocks, composed of silicon and oxygen , and has the convenient property of being negatively charged, which attracts the positively charged elements calcium, iron, magnesium, potassium, and phosphorus — essential for plant growth. Clay particles also hold large amounts of water.
What are the rocks that make up the soil?
Geology for Gardeners. In the beginning, there were rocks — originally granite and basalt, and later shale, slate, limestone, and sandstone. Soils are the product of the weathering of those rocks, whether through mechanical means (such as erosion from wind or water) or chemical means (such as oxidation or hydrolysis).
How To Make Loam Soil?
It is a blend of elements that supports plants through thick and thin. To build the best sandy loam soil, you’ll need to include topsoil, compost, peat moss or coir, perlite, and coarse sand. Sandy loam soil gets its name by being one-half clayey loam soil mixed with one-half sandy soil.
Characteristics Of Loam Soil

What happens if you put too much clay in soil?
Soil that is too sandy won’t form a ball; it will just crumble. Soil that has too much clay will form a tight, hard ball. Silty and loamy soils will form a loose ball that is slightly crumbly. Another method is to fill a mason jar halfway full of the soil in question, then add water until the jar is ¾ full.
Can you form a ball with clay?
When damp, you cannot form it into a ball with your hands, as the ball will just crumble away. Sandy soil doesn’t hold water, but it does have plenty of space for oxygen. Clay soil feels slippery when wet and you can form a tight hard ball with it. When dry, clay soil will be very hard and packed down. Silt is a mixture of sandy and clay soil.

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 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.
Why do plants need loamy soil?
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.
Why do you need to amend your soil?
Creating optimal loam is an ongoing process—you’ll need to amend your soil annually because growing plants use up nutrients and water that runs off can also take nutrients with it. If your soil is heavy in clay or sand, you won’t fix it the first year—but you will improve it.
Benefits
Example
- However, if we had to measure that ratio out every time we made a garden, there would be far fewer gardens.
Properties
- On the opposite end, clay particles are much smaller and easily compact. That makes clay a great material for building bricks, but not so great for allowing water, air, and plant roots through. However, clay tends to be higher in nutrients than the other soil components. Silt is the medium size particle, with better moisture retention than sand, but fewer nutrients than clay. Silt helps cl…
Effects
- Although loam is a combination of sand, silt, and clay, adding sand to your clay soil, or vice versa, will not create loam. Doing so will result in something like cement.
Introduction
- Creating a loose, loamy, fertile soil is not a once and done garden task. Turning your existing soil into loam is an ongoing process that involves working organic matter into the soil every year. It is the decomposing organic material that creates the well-draining conditions plants need. It is also the organic matter that attracts the beneficial organisms that will help keep the soil healthy and …
Preparation
- Unfortunately, organic matter is quickly depleted as it decomposes. It will need to be amended each season. How much to add depends on how out of balance your soil is. If your soil is extremely sandy or predominantly heavy clay, it may need large amounts of organic matter added several times a season. However, for most soils, laying down at least a two-inch layer of organi…
Risks
- A word of caution: Buying soil in bulk can be a fast, easy way to get your garden or yard up and growing, but there is no standard or certification for soil quality, so you never know what you are getting. Many companies that sell soil are getting that soil from construction sites, where soil has had to be excavated for basements or to level a yard. Generally, soil from excavation does not m…
