To visualise the effect of biologically active fertilizer to root grow, the peas (Pisum sativum) were placed in a rhizobox filled with the dirt. Rhizobox was inclined under 45 degrees for positioning of the growing roots closer to the lower wall in response to gravity. On the left part of rhizobox were Control peas and on the right side were peas soaked in biologically active fertilizer for 6 hours. Peas were grown in rhizobox for 16 days.
