• Abstract

   

  This study investigates fertilizer consumption patterns across 41 countries from 1961 to 2021. Descriptive statistics reveal substantial variation in average fertilizer use (kg/hectare) and variability between countries. Statistical analyses confirm significant differences in consumption patterns, with fertilizer consumption identified as a major explanatory factor. Cluster analysis further differentiates countries into two groups based on their consumption levels. These findings highlight the need to consider fertilizer use within a country-specific context. Further research exploring the underlying factors driving these variations and their impact on crop yields could inform strategies for optimizing fertilizer use and promoting agricultural sustainability.
