While most compost is applied on the farm where it is produced, it may be sold off the farm. The most logical customers are local crop farmers who do not have livestock operations. Sales, or trades of compost for grain or forage, or gifts of compost to non-farm neighbors with gardens, can enhance relationships within the community. Other outlets for compost include nurseries, landscapers, garden centers and soil blenders. The key to all markets is compost quality and consistency as required to meet the customers' needs - the compost may need to be tested for nutrient content and labeled, or for maturity.
Poor compost can release odor and even kill plants as it releases ammonia and heat.
