Accumulations of copper in apple orchard soils: distribution and availability in soil aggregate fractions

Purpose The particle fractions of soil influence the retention and availability of heavy metal. However, the accumulations of Cu in aggregate size fractions of apple orchard soils due to the long-term application of Cu-based fungicides remain poorly understood. This study aimed to investigate the di...

Zusammenfassung:Purpose The particle fractions of soil influence the retention and availability of heavy metal. However, the accumulations of Cu in aggregate size fractions of apple orchard soils due to the long-term application of Cu-based fungicides remain poorly understood. This study aimed to investigate the distribution and availability of Cu in various aggregate fractions of soils from different aged apple orchards. Materials and methods Soil samples were collected from orchards with 10, 20, 31, 45, and 50 years old. Soils were partitioned into four aggregate fractions (>2000, 2000–1000, 1000–250,
