Soil is very common in our daily life. In addition to planting, soil can also be used in architecture and art.
The nutrient-rich soil currently sold on the market is widely selected by gardeners. Nutrient soil has a wide range of applications; sufficient nutrients, water, and fertilizer retention. Nutrient soil can be divided into many types, like garden soil, potting soil, potting mix, topsoil, and raised bed soil. What is the difference, and how do we need to choose the soil correctly?
The most important thing for planting is the soil. Excessive acidity and alkalinity, compaction, and airtightness can easily cause plant root necrosis, unhealthy plants, and poor growth. If the soil water absorption and drainage are not good, the plants will die from drought and waterlogging. If we fail to provide a good material basis, the plants will naturally grow poorly.
Topsoil: Topsoil is often used as fill soil because it is not mixed with impurities such as organic matter. And topsoil is too dense and nutrient-poor to provide nutrients for plants to grow, so topsoil is often used in lawns or as a fill in the bottom layer of garden beds to reduce weed growth.
Land soil: Land soil is the common soil in our daily life, also known as vegetable garden soil and pastoral soil. When cultivating plants, it needs to be used with fertilizers. The aggregate structure is usually not recommended for direct cultivation of plants. One of the reasons is the lack of nutrients. Another important reason is that the land's soil structure is simple; it is very easy to compact when dry and it is water permeable when watering.
Garden soil: This is soil that has been formulated to make it better for plants and contains most of the nutrients that plants need to grow. Its soil composition is rich in compost, microorganisms, nutrients, organic matter, and ideal pH. It has a good soil structure, which not only effectively provides plants with the nutrients they need, but its good moisture retention also leads to higher output.
Compared with topsoil, garden soil has a looser structure, better ventilation, stronger water and fertilizer retention capacity, and is more suitable for the growth of garden bed plants.
Potting soil: Potting soil and potting mix can usually be interchanged. But there are also some differences. When purchasing potting soil or potting mix, you can carefully look at the ingredient list on the package to decide which one is right for you.
Potting soil is mainly used for potted plants. Potting soil may or may not contain soil, which is mainly distinguished by the ingredient list on the package. Most potting soil contains compost. And it is not sterile; it may contain fungi and weed seeds. Potting mix is soilless and sterile, which may contain fertilizers, and has a fluffy texture.
Raised bed soil: Compared with other soils, raised bed soil is more expensive, rich in organic matter, fluffy soil, and has better air permeability. Raised bed soil does not require frequent watering because its moisturizing properties are better.
But is raised bed soil the only option to fill the raised garden beds
? To be honest, potting mix is also good for garden beds. The main reason for this choice is that filling garden beds does not require the entire bed to be filled with soil (What to fill raised garden bed with
). When choosing to fill the garden bed, choose organic or organic soil with good air permeability.
In general, the soils on the market have their own merits, and the composition of each soil is different. When we choose soil, it is the best way to choose soil mainly according to the container and pH requirements of the plants.
