Temporal Trends in Available Phosphorus Across Four Types of Agricultural Fields from 2013 to 2020

초록

Phosphorus (P) is a vital nutrient for global agriculture, playing a pivotal role in crop germination and growth. However, improper usage of phosphorus can lead to detrimental effects on crops and significant environmental pollution. This study investigates the changes in available phosphate (P2O5) concentration in agricultural fields across 17 regions in South Korea from 2013 to 2020. During the study period, the total agricultural land area consistently decreased. Although rice paddy fields accounted for the largest proportion of the total agricultural area, the available P2O5 accumulation was the lowest due to low available P2O5 concentration. In contrast, soils within greenhouses accumulated excessive levels of available P2O5, significantly exceeding the recommended range. This underscores the importance of improved fertilizer management in greenhouses for the future sus tainability of agriculture.
