Abstract
Phosphorus (P) leaching from agricultural soils is a growing environmental concern in Oman, particularly in the Al Batinah region where sandy soils and heavy fertilizer use have led to elevated phosphorus levels near palm farms.
This study aimed to assess the effectiveness of iron-enriched biochar, produced from locally sourced palm tree waste through pyrolysis at 600 °C—in reducing phosphorus mobility and leaching in sandy soils.
