Abstract
Cover crops are beneficial to soil structure and processes and can provide nitrogen (N) to a subsequent crop. Practical studies of N availability from cover crops and organic fertilizers in naive (transitioning) soils are helpful for growers to achieve desirable yield. Microbial soil inoculants (biostimulants) may enhance availability of organic N sources. We found a spring-planted pea-oat cover crop provided less than 27 pounds of N to a subsequent broccoli crop, and no impact of a commercial biostimulant on broccoli yield or development rate. Availability of N from organic amendments used is discussed.
