Why should I Use Southwaste Compost?

Compost has been studied for years by agriculture and horticulture professionals and has been shown to have a multitude of benefits across varying applications. Southwaste compost is approved by the US Composting Council’s for lawns, shrubs, trees as well as vegetable and flowers.


Application of compost aids in soil retention in a multitude of ways. Compost has demonstrable improvements for moisture retention. By improving moisture, our customers are able to reduce water loss, nutrient leaching, and prevent unnecessary and wasteful soil runoff. Preventing runoff allows for large scale growing and landscaping organizations to retain precious water and soil nutrients.


In addition to retaining soil and water, the supply of organic matter provided by compost aids in the proliferation of soil microbes and beneficial microorganisms that can encourage root growth of plants. Compost is able to improve soil aggregation and likely makes plants more able to uptake nutrients. Certified compost could lead to larger yield and more effective plant growth for large scale horticultural and agricultural ventures.


Composting things that otherwise could have ended up in a landfill also helps to preserve the environment by keeping waste out of our landfills and instead adding valuable nutrients to soil and plants. Adding valuable compost to landscapes also preserves water and decreases fertilizer applications in a way that can help preserve our natural environment.
