Compost vs Topsoil: Pros and Cons. Which one is better?

4. Compost or Topsoil: Which is Better?

Now that we have looked at the pros and cons, it might be challenging to support one over the other. Take a look at the contrast.

Topsoil is the top layer of soil that is better for basic gardening tasks, while compost is the decomposed organic material suitable for pots or hungry plants. While compost is a slow-release fertilizer that excels at containing organic matter and minerals, topsoil is superior at holding moisture for a longer length of time. Topsoil includes weed seeds, previously used fertilizers, and insecticides while being less expensive. On that basis, compost is brimming with advantageous organisms despite being pricey. Given the above, there are a number of considerations that must be made in order to distinguish one as superior to another. 

Compost is probably what you need if you want to create healthy gardens, nourish your container plants, or loosen up compacted soil. All of these requirements may be met by composting. The majority of gardeners, at least once a year top-dress their flowers, plants, and perennials using compost.

Contrarily, topsoil is often employed to establish a new yard or to improve rocky soil in your backyard. It may be dispersed over the top of your yard's soil. It will decompose over time and release nutrients into the soil. Compared to compost, topsoil is much better at holding onto its structure and moisture. To add bulk to raised beds, flowerbeds, or garden beds, topsoil may be utilized (but compost is preferable if you're just making a small area or raised bed). It doesn't provide your garden plants with all the nourishment they need on their own. This is why it is usually advised to combine topsoil with additional materials when filling new raised beds, such as compost and manure. In order to promote healthy plant development, dirt and compost are often used as filler in raised bed gardening. Typically, topsoil is only applied to a garden bed once, and each year after that, it is replenished with organic compost.

For instance, you should aim to increase the depth of your topsoil layer before establishing a new lawn. Usually, 2-3 inches of fresh topsoil is sufficient. You may sow the grass seeds once the dirt has been deposited. Add a layer of compost as a topdress to your new grass afterward. The grass seeds will be covered with compost, which will shield them from birds and other pests. The new topsoil will eventually absorb it, generating nutrient-rich soil that can support beautiful, healthy lawns.
