The study looked at how using sorghum green manure and reducing fertilizer affected soil and celery growth in a greenhouse. The results showed that using sorghum green manure and less fertilizer improved soil quality by increasing organic matter and nutrients like nitrogen and phosphorus. This led to higher celery yields and increased beneficial bacteria in the soil. The green manure also helped the soil use fertilizer more efficiently. Overall, adding sorghum green manure and reducing fertilizer can improve soil health, increase crop yields, and benefit the environment.
