When our goal is to have seed germinate quickly, establish large root systems, and have strong seedling vigor, we need to support seeds with the trace minerals and biological symbionts they should have had if they were grown in optimal conditions.
The row starter solutions we recommend always include microbial inoculants and a broad range of trace minerals.
This field of organic green beans was planted with an AEA row starter applied in-furrow. The two check blocks are comparisons of competing products. I don’t know what they contained, but it seems safe to suggest they lacked the nutritional and microbial support needed to establish strong seedling vigor and build the plant frame needed for large yields.
