As we move towards a circular bioeconomy, an increasing amount of soil amendment are being made from wastes. They are an exciting and valuable source of nutrients, organic matter and beneficial microbial activity but these wastes are also a source of risk that must be carefully managed.

See Using Compost Safely for more information on applicable risks, regulations and standards.

Most suppliers can produce quality composted soil amendments (CSA), but there is always a temptation to take shortcuts and reduce costs. Often, it’s hard to see the difference just by looking at CSA. You need to know what information to ask for and how to interpret that information.  That’s where we come in.

By using compost in agriculture, you can:

  • Build levels of soil organic matter, humus and beneficial microorganisms that improve soil structure and health
  • Improve water infiltration and soil water holding capacity
  • Reduce erosion risk and crusting of surface soils
  • Provide slow-release nutrients and feed the microorganisms that help plants access nutrients already in the soil
  • Benefit from compost teas and extracts, which are also used to improve soil biology and supress disease

It sometimes takes several years for the benefits of compost use to become apparent, particularly at lower annual application rates. Compost application should be used in conjunction with other regenerative agricultural practices that conserve organic matter and improve soil biology like cover-cropping, minimum tillage, and livestock rotation. Equally, practices that actively deplete soil organic matter and reduce biological activity in the soil will reduce or even negate the benefits of compost use.


Case studies have demonstrated the positive effects of using composted soil amendments (CSA) in agricultural production. But not all CSA are created equal. And not all CSAs are fit-for-purpose.
