Organic Amendments: The Good, the Bad and the Ugly

by Jean Reeder

Routine applications of organic matter should be considered an essential component of gardening and soil management since organic matter improves soil properties such as water and nutrient holding capacities, aeration and drainage.  However, over-amending is a common problem, as many gardeners do not appreciate the potential problems of adding too much organic matter.  The quality of commercially-available organic amendments ranges from excellent to poor.  This class covers the different types of bagged organic amendments available and the criteria for evaluating the quality of an organic amendment.  Quality data for different types of organic amendments are presented.

A soil test is the best method to determine the need for the addition of fertilizer nutrients.  However, many gardeners have difficulty converting a soil test recommendation into an actual amount of fertilizer to apply.  This class covers the types of commercial organic and inorganic fertilizers available, and presents an easy method for calculating fertilizer application rates.

Jean Reeder worked 30 years for the USDA Agricultural Research Service in Fort Collins conducting research studies on the properties of soils in range land and disturbed land ecosystems in Colorado and Wyoming. She is now retired and thoroughly enjoying her garden and teaching soils classes to other gardeners.
