When should you use silt soil? ›

Moisture-loving plants in particular tend to thrive in silt soil. Vines, lush grasses and richly colored flowers are some examples of plants that are especially well-suited for silt soil.

Silty soil is usually more fertile than other types of soil, meaning it is good for growing crops. Silt promotes water retention and air circulation. Too much clay can make soil too stiff for plants to thrive.

Shallow-rooted vegetables like lettuce, onion, broccoli, and other related brassicas are good options. Nitrogen-fixing vegetables like peas and legumes are also great to further amend your soil. A plot with silty soil would be well suited for a Three Sisters garden with corn, beans, and squash.

The greater surface area relative to volume can result in long-lasting water retention. This in turn may causes silty soil to expand and shift. This lack of stability means that structures on silty soil are subject to repeated and prolonged stress, potentially resulting in structural damages.

Fill dirt can consist of any material – sand, clay, gravel, and so on. Fill dirt is commonly made of subsoil, which is found about 12 inches below the topsoil. It consists of partially broken down soil that contains clay, sand, silt, and stones, and any other materials found in the source ground.

Last, silt is another soil type that makes up topsoil. Silt is usually very high in the nutrients that plants love. Combining the right proportions of sand, clay, and silt make up the perfect topsoil. That's why it's always important to thoroughly inspect your topsoil prior to making a purchase.

Because of this, gardeners usually amend silt soil, mixing in mulches, fertilizers, drainage assistance particles, such as sand, or other soil additives to solve drainage issues and provide the proper growth medium for most plants.

What are the problems with silt? ›

If silt blocks inlets and outlets preventing water flow, the possibility of stagnant water which smells and looks extremely unpleasant becomes a distinct possibility and the high nutrient levels of the silt encourages dense algae blooms, spoiling the water quality and aesthetics.

Some gardeners also like to add organic matter to silt soil to make it more suitable for plants. Plants that do well in silt soil include swamp milkweed and the yellow iris. If you're using drained light silt soil, you could grow a number of crops including wheat, potatoes, and field vegetables.

The silt also contain high concentration of potassium which is suitable for agriculture soil that are needed by most plant to growth. The absent of lead which is type of heavy metal in the silt indicates that the silt also suitable to become an agriculture soil.

Silty Soil

If proper drainage is provided, silt is excellent soil for your garden. The addition of compost and mulch can improve the drainage and structure of the soil. Plants to grow in silty soil: Climbers, grasses, decorative perennials, shrubs like Mahonia and New Zealand flax.

The rich, fertile silt provided excellent ground for growing crops. The Egyptians used the irrigation system of reserved flood water to help keep the farmland wet during the very dry months with special equipment such as a shaduf.

Assallay and coinvestigators further divide silt into three size ranges: C (2–5 microns), which represents post-glacial clays and desert dust; D1 (20–30 microns) representing "traditional" loess; and D2 (60 microns) representing the very coarse North African loess.

Like sand, silt particles are relatively large and leave gaps, so water can flow through easily. However, they do stick together more than sand, so they retain more water for longer periods of time.

It retains large amounts of water for a long time. As it dries out, it shrinks down. This expansion and contraction can cause issues if a building's foundation rests within it. Whenever possible, it's best to avoid building in silty soils.
