Scientists prove the effectiveness of split nitrogen application

In a two-year study conducted in Hefei, China, scientists compared different nitrogen application schemes. Using portable ammonia (NH₃) detectors, they measured emissions from soil and corn leaves, which together represent total NH₃ losses under field conditions.

The study found that high ammonium (NH₄⁺) concentrations in soil combined with low moisture levels lead to significant NH₃ losses from soil. At the same time, a larger leaf area and high NH₄⁺ concentrations in the leaf apoplast increase emissions from plants.

The results clearly demonstrate that split nitrogen application is a more sustainable practice that minimizes NH₃ losses and improves corn yields. The findings are also important for optimizing agronomic practices and reducing air pollution.

Soil nutrient content has a major impact on the growth, development, and productivity of crops. The presence of phytopathogenic fungi and nematodes in soil also affects yield quantity and quality.
