When it comes to gardening and garden projects, its easy to get confused about the various types and names of soils that get thrown around. For example topsoil, garden soil, garden mixes, turf underlay and top dressing just to name a few. Let’s delve into this deeper and get a better understanding of the various soil types

What Are The Six Main Types Of Soil?

The 6 main types of soil are:

  1. Sand. Sand consists of large particles that allows for rapid drainage but poor water and nutrient retention. It’s often used in raised beds and under lawns to improve drainage.
  2. Silt. Silt particles are smaller than sand, which allows it to hold more water and nutrients. However, it still drains quickly and can become compacted.
  3. Clay. Clay soil is made of the smallest how to find the best movies on streaming platforms particles and holds the most water and nutrients. However, it drains poorly and is prone to compaction.
  4. Loam. Loam is a balanced mixture of sand, silt and clay, making it the ideal soil for most plants. It has good drainage, water and nutrient holding capacity while remaining loose and aerated.
  5. Organic soil. Also known as peat or muck, organic soil is made up of decomposed plant material. It has high water and nutrient holding ability but drains poorly.
  6. Modified soil. Modified soils have been altered through the addition of materials like compost, perlite or sand to improve the structure and drainage of heavier clay or organic soils.

What is Topsoil?

Topsoil refers to the uppermost layer of soil consisting of loose material like sand, silt and clay mixed with decomposing plant and animal matter. Topsoil is usually between 4 to 8 inches deep and contains the majority of soil nutrients needed by plants. The organic matter in topsoil helps retain water and nutrients, improving the soil’s structure and aeration. Healthy topsoil teems with beneficial organisms that recycle nutrients and make them available to plant roots. Topsoil is dark in color due to its humus content, and it is loose and easy to dig with your hands.

What is Garden Soil?

Garden soil refers to any type of soil used in planting beds, containers and lawn areas. Garden soil can be the existing native topsoil on your property or purchased garden soil mixes. Good garden soil is loose, well-aerated and has good drainage. It contains between 3% to 10% organic matter to provide nutrients and retain moisture. The ideal pH range for most plants and lawns is between 6.0 and 7.0. Garden soil should be tested periodically to determine its nutrient content and pH level. Adding compost and other amendments can improve the structure and fertility of garden soil over time.

What are Garden Mixes?

Garden mixes are bags or loose bulk premixed soil blends designed for specific garden uses. There are mixes for raised beds, containers, lawns, vegetable gardens and more. These mixes typically contain a base of topsoil and organic matter like compost combined with materials like perlite or sand to improve drainage and aeration. The ideal ratio of components varies depending on the intended use. Garden mixes aim to provide fertile, well-structured soil that’s ready to plant into right out of the bag

clean fill soil Soil

Fill Soil (Unscreened)

Fill soil, also known as general fill soil, is a mixture of sand, silt, clay and organic materials that is used as a base layer or foundation fill under structures, patios, walkways and other hardscape elements. It provides a stable base and level surface to build or install structures upon.

Fill soil differs from topsoil or planting mix in that:

• It is not screened to remove rocks, debris or organic materials. This makes it less expensive and suitable as a base fill rather than a planting medium.

• It often has a higher clay and sand content with less organic matter. This makes it more stable and less prone to settling over time.

• It is typically not amended with fertilizers or other additives to improve plant growth. Fill soil is meant to provide structure and stability rather than nourish plants.

Benefits Of Using Garden Mixes

Garden mixes provide numerous benefits for gardeners, including: Garden mixes aim to mimic ideal “loam” soil conditions to provide the best growing medium for a wide variety of plants. The components are selected and balanced to create soil that drains well while also retaining adequate moisture and nutrients. This can improve plant health and growth rates compared to unmodified native soil.

The premixed and balanced nature of garden mixes also reduces the risk of under- or over-fertilizing plants. The nutrient levels in the mixes are formulated to provide the appropriate amount of food for common plants and vegetables. This simplifies the fertilizing process and reduces the risk of burning plant roots.

They Save Time

Garden mixes contain all the necessary ingredients in the proper ratios to create high-quality soil. This saves the time and effort of mixing and amending soil ingredients yourself.

They Provide Balanced Nutrients.

Garden mixes are formulated to provide an optimal balance of nutrients for healthy plant growth right from the start. This reduces the need for additional fertilizers.

Which Type Of Soil Is Best To Use In A Garden In Newcastle, NSW

The soil type that tends to work best for most gardens in Newcastle, NSW is a clay loam soil. Clay loam soils have a good balance of clay, silt and sand particles that allow for proper drainage, water retention and nutrient holding capacity. Some key points about using clay loam soil in Newcastle gardens:

• Clay loam soils have higher water retention abilities due to their clay content. This means less frequent watering is needed for plants during hot Australian summers.

• The loamy texture of clay loam provides good drainage to prevent waterlogging of plant roots. Excess water drains out while enough moisture is retained for healthy plant growth.

• Clay loam soils tend to have good fertility and can supply plants with essential nutrients like phosphorus and potassium that are held by the clay particles.

• Adding organic matter like compost and aged manure to clay loam soils can further improve their structure, aeration and nutrient levels. This makes clay loam a good candidate for soil amendments.

• Most plants grow well in clay loam soils as long as proper drainage is provided. Vegetables, flowers, lawns and trees tend to thrive in this soil type with regular amendments.

Frequently Asked Questions (FAQs):

While both potting mix and garden mix are used for growing plants, they serve different purposes. Potting mix is specifically designed for container plants. It is lightweight, provides excellent drainage, and contains a balanced mix of nutrients necessary for potted plants. Garden mix, however, is intended for adding nutrients and organic matter to garden soil, improving its overall structure and fertility.

For garden beds, organic garden soil or compost is the best option. These kinds of soil are rich in nutrients and provide an ideal environment for plants to thrive. They have a good balance of drainage and water retention, and they foster microbial activity, which is beneficial for the health of your plants.

When planting a new lawn, the best type of soil to use is turf underlay and top dressing. Turf underlay provides a solid foundation on which your turf can establish its roots, while top dressing improves the soil’s structure and fertility, and helps to keep it level.

The best type of soil for grass is a combination of sand, silt, and clay soils, also known as loam soil. Sandy loam, for example, provides an excellent balance between drainage and nutrient retention, making it ideal for healthy grass growth.

There are a few ways to improve heavy clay soils for gardening:

• Add organic matter: Compost, manure, peat moss and mulch can be worked into the soil to introduce organic matter that will help break up clay particles, improve the soil structure and increase nutrient levels.

• Raise beds: Constructing raised garden beds filled with improved soil or a soil/compost mix is a good option for clay soils. The beds allow for better drainage and aeration for plant roots.

• Grow in containers: Filling containers with a commercial potting mix is a good alternative to dealing with clay soil, allowing you to grow plants that would otherwise struggle.

• Add gypsum: Gypsum works its way between clay particles to break up the soil structure and improve aeration, drainage and workability. It needs to be worked into the soil several times over multiple seasons to be most effective.

• Lay down organic mulch: Placing 2-4 inches of organic mulch like straw, shredded leaves or bark chips on top of garden beds can help keep clay soil from getting compacted by rain and foot traffic.

The main nutrients plants require in the soil are nitrogen, phosphorus and potassium. Micronutrients like calcium, magnesium and sulfur are also needed in smaller amounts. A soil test will determine if your soil is deficient in any nutrients.

Weed seeds are persistent in soil, so prevention is key. Methods to remove existing weeds include hand-pulling, using a hoe, applying mulch, or spot-spraying with weedkillers. Solarization involves covering moist soil with clear plastic to “cook” weed seeds.

The ideal soil for planting should be lightly firm but fluffy. It should hold its shape when squeezed but break up easily when disturbed. This indicates good aeration and drainage while still providing support for roots. Soil that is too compacted or too loose are both problematic for plant growth.
