NUTRIENT INPUTS FOR COOL SEASON GRASS PRODUCTION

Cool season grass species have the potential to provide relatively high quality forage for the fall and spring months. The digestibility of dry matter of cool season grasses is generally higher than warm season grasses, and annuals tend to be higher than perennials. The yield and quality of cool season grasses can be significantly affected by nutrient inputs, hence growers are well advised to carefully evaluate fertility programs for cool season grass production going into the fall.

While a comprehensive overview of cool season grass fertilization is not possible here, following are a few examples of how production of some species can be affected by nutrient inputs.


Cool season grasses can provide excellent forage for grazing and hay production. Both yield and quality can be dramatically impacted by nutrient inputs. Soil tests should be used as guidelines for nutrient application. However, factors such as experience, nutrient removal, and local information can also be useful in developing nutrient management programs for cool season grasses.
