Recently, the "Study on the Methods of Soil Nutrient Supply Strength and Proportional Fertilization Theory," conducted by the Shanxi Academy of Agricultural Sciences in collaboration with Nanjing Agricultural University, has successfully passed expert review. This groundbreaking research challenges the long-held international belief that adding more fertilizers no longer leads to increased crop yields. The findings offer a new approach to optimizing fertilizer application techniques, with the potential to significantly boost food production in the future.
Currently, some experts argue that the productivity gains from fertilizers have reached a plateau, suggesting that further use of chemical fertilizers will not enhance yield. However, Qi Qinghe, the project leader and researcher from the Shanxi Academy of Agricultural Sciences, conducted extensive field experiments that revealed a different perspective. According to his research, crop yield is not only influenced by the quantity of fertilizer applied but is also heavily dependent on the balanced proportion of nutrients. The optimal fertilization ratio is closely tied to the specific types of soil nutrients present.
Moreover, Qi found that for each crop variety, there is an optimal level of fertilizer application. Beyond this point, additional fertilization does not improve yield and may even be detrimental to plant health. This discovery highlights the importance of precision in nutrient management, ensuring that farmers apply just the right amount of nutrients without overdoing it.
Based on the fertilization theory developed through this study, Qi tested various crops such as corn, wheat, rice, tobacco, and potatoes on different soil types—ranging from low nitrogen and high phosphorus to low nitrogen and phosphorus, and high phosphorus with low potassium. The results showed a consistent increase in production by approximately 30% across all tested crops, demonstrating the effectiveness of the proportional fertilization approach.
This innovative method could revolutionize modern agricultural practices, helping farmers maximize their output while minimizing waste and environmental impact. As global food demand continues to rise, such scientific advancements are crucial for sustainable farming and food security. With further research and implementation, this theory has the potential to reshape how we think about fertilization and soil management worldwide.
