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.
