Can You Use Compost As Mulch?

Mulch is any protective material that you use to cover the soil’s surface to control weeds, retain moisture, and enhance appearance. And the thicker the mulch, the more difficult it is for weeds to grow. Moreover, using compost as mulch is an effective way of adding nutrients to the soil and keeping it in good condition. At the same time, it also helps improve the soil’s structure, drainage, and nutrient-holding capacity. High-quality compost is a great amendment to enhance the soil by providing nutrients, organic matter, and beneficial microbes.

Furthermore, compost is an ideal mulch, especially for organic gardeners. It is a cost-effective way to cover the topsoil. However, remember to place a decent quality compost since it will serve as the primary medium for your plant’s growth. Hence, the quality of compost mulches does matter a lot.

Why Is Compost Considered As The Best Mulch?

1.) Saves You Money

Compost blanket treatments are more cost-effective than other systems and treatments that do not use them. Indeed, it reduces energy use associated with transporting water and producing synthetic fertilizers and pesticides.

2.) Increases Soil Nutrients

It provides soil nutrients in a stable organic form such as; increasing plant rooting depth, enhancing physical, biological, and chemical soil properties, and the decrease of soil erosion. Additionally, nitrogen, potassium, and phosphorus are the critical nutrients for your plant’s growth. And it so happened that compost is abundant in these three primary nutrients.

3.) Helps Make Plants Grow Faster

Scientists have found that adding a compost blanket decreases pest damage, and produces bigger flowers and vegetables. Indeed, organic waste can significantly increase plant growth. And the production of stems and leaves also increases with the continuous addition of organic materials.

4.) Reduces Greenhouse Gas Emissions

Compost blankets decrease landfill methane emissions (Methane is a major source of global greenhouse gas). Composting is an aerobic process that decreases or prevents the release of methane during organic matter breakdown.

5.) Essential Component In Water Management

Compost increases the water holding capacity of your soil. It helps replenish groundwater and at the same time enhances water quality by adsorbing contaminants and capturing sediment. Therefore you can conserve water consumption while enhancing water infiltration and storage.

6.) Reduces Use Of Synthetic Fertilizers And Pesticides

The continuous use of compost blankets encourages gardeners not to use synthetic fertilizers and other chemicals. The use of alternative fertilizers like compost may result in positive effects on the soil by increasing the organic matter, improving water retention, and soil texture decreasing erosion rate.

7.) Encourages Earthworms And Other Microbial Organisms

Earthworms and other microbial organisms are vital to plants since they aerate the soil and break down organic matter such as leaves into important nutrients for plants to grow.

8.) A Natural Flood Control

It intercepts and filters falling rain, reducing runoff and associated sediment losses alters soil structure, and prevents soil erosion. Also, increasing plant growth and soil cover.

9.) Protects Plants From Diseases And Pests

Compost feeds the bacteria, fungi, and other beneficial organisms that transform and release nutrients preventing plant diseases and pests. At the same time, it suppresses harmful pests and diseases that could overrun lifeless, poor soil.

10.) Regulates Soil Temperature

The extreme temperature may affect the growing roots of your plants. Compost as mulch covers the soil surface and is a good help in keeping the soil temperature beneficial for your overall plant growth.
