Compost

Compost makes soils happy!

Compost is the result of decomposition of organic material in a controlled environment. Compost provides Soil Organic Matter (SOM), nutrients, and beneficial microorganisms. SOM stimulates microbial activity and increases the water-holding ability.

Side or topdress along established plants or perrenials, or blend into soil or grow medium. Compost looks like soil but it is not, and should not be used as a stand-alone grow medium (it is too strong!). An established bed that's doing well only needs a 1/2'' layer of compost; rake it in lightly. You can be more generous if it's been a while since it has received compost. A little goes a long way to build a healthy living soil ecosystem!

Specific weight of compost can vary 500-600 kg/m3 depending on moisture content, with typical value at 550 kg/m3.
