Soil is made of what silt sized particles?
Silt soil is made up of medium-sized particles that are larger than clay particles and smaller than sand particles. Silt particles are smooth, fine-grained, and retain water well while also offering good drainage. Soils with a high silt content are typically fertile and suitable for farming.
Does silt absorb more water than clay?
Silt has larger particles than clay, so it typically absorbs water more slowly but can hold more water overall. Clay particles are smaller and have a higher surface area, so they absorb water quickly but may not retain as much water as silt in the long run.
Compare and contrast the subsoil of the three types of soil?
Sand: Subsoil of sand is typically coarse and does not retain water well, leading to poor nutrient retention. Silt: Subsoil of silt is fine-textured and holds water better than sand, but can still be prone to compaction and drainage issues. Clay: Subsoil of clay is heavy and holds water and nutrients well, but can become waterlogged and difficult to cultivate when too wet.
Does silt make soil dark and spongy?
Yes, silt is a type of sediment that is fine-textured and can help improve the soil's ability to retain water and nutrients. When mixed with soil, silt can contribute to making the soil dark and spongy due to its small particle size and water-holding capacity.
How is soil categorized?
Soil is categorized based on its texture, which refers to the relative proportions of sand, silt, and clay particles it contains. Soils are classified as sand, silt, clay, or loam (a mixture of sand, silt, and clay). These categories help determine the soil's ability to retain water and nutrients, as well as its suitability for different types of plants.

How much water can silt hold?
Silt can hold a significant amount of water due to its fine particles and large surface area, typically retaining about 20-30% of its weight in water. This ability to retain moisture makes silt beneficial for agriculture, as it supports plant growth. However, the exact water-holding capacity can vary based on the specific composition and structure of the silt.

How well does loam hold water?
Loam soil holds water quite well due to its balanced texture of sand, silt, and clay particles, allowing it to retain moisture while also draining excess water. This makes it ideal for providing consistent moisture to plant roots without becoming waterlogged.
Is silt good for farming?
Yes. It is usually more fertile than other types of soil, as it has highly adequate water-holding capacity and enough space between the granules to allow oxygen and air to seep into. The fertile agricultural lands near the Nile river contains a lot of silt, which is why it is so popular for growing crops in.
Can water pass through silt?
Yes, water can pass through silt because silt has small particles that allow water to flow through them. However, the rate at which water passes through silt will depend on the porosity and permeability of the silt particles.
What soil can retain the most water?
Silt loam soil typically retains the most water among soil types. It has good water-holding capacity due to its balanced mix of sand, silt, and clay particles, which allows for adequate drainage while retaining moisture for plant roots.
What are the different kinds of soil?
The main types of soil are sandy, clay, silt, and loam. Sandy soil has larger particles and does not retain water well, while clay soil has smaller particles and retains water tightly. Silt soil has medium-sized particles and provides good drainage. Loam soil is a mixture of sand, silt, and clay, making it ideal for plant growth.
What happens to silt in water?
When silt is suspended in water, it remains dispersed due to its fine particle size, which allows it to stay in suspension for extended periods. Over time, if the water slows down or becomes stagnant, silt can settle to the bottom, forming sediment layers. This process can affect water clarity and quality, as well as the habitats of aquatic organisms. In rivers and streams, silt can contribute to the formation of riverbanks and deltas as it accumulates.
