Paper Summary

The researchers studied how humic acid in Black Soil changed over years with different fertilization methods. They used advanced techniques to analyze the structure of humic acid in soil samples collected from 1997 to 2012. The results showed that using organic manure with NPK fertilizers made the humic acid more aliphatic and simpler over time. This combination of fertilizers helped meet the crop's nutrient needs and saved costs.
