Use as a Soil Conditioner

Barr-Tech’s compost is a smart and effective way to enhance the health and stability of your lawn or garden. It can be used for many of your outdoor projects, including landscape, garden, turf, erosion control and agricultural applications.  To apply our compost, simply spread a uniform 1”-2” layer and mix it into the top 4”-6” of topsoil. After applying compost, a simple soil analysis is recommended to determine any additional fertility needs; IT IS IMPORTANT NOT TO OVER FERTILIZE AND OVER WATER.
