Compost Management on Organic Farms

Compost Application Rates

Calculating application rates for compost is similar to figuring the application rates for manure on cropland as discussed in Chapter 10, Manure Management on Organic Farms. Compost should be considered a slow-release source of nitrogen. Most nitrogen remaining after completion of the composting process is bound into organic forms and thus not available immediately for plant uptake. As a consequence, application rates are generally higher, allowing for greater organic matter additions to soil.
