Influence of tillage practices on phosphorus forms in aggregates of Mollisols from northeast China

BACKGROUND Phosphorus (P) is an essential mineral nutrient for crop growth and development. Much remains unknown regarding the content and distribution of P forms in different soil aggregates as affected by tillage practices. A 3‐year field experiment was conducted to investigate the effects of no‐t...

Description
Summary:BACKGROUND Phosphorus (P) is an essential mineral nutrient for crop growth and development. Much remains unknown regarding the content and distribution of P forms in different soil aggregates as affected by tillage practices. A 3‐year field experiment was conducted to investigate the effects of no‐tillage (NT), rotary tillage (RT), subsoiling (SS), and deep tillage (DT) on soil aggregate distribution pattern, aggregate‐associated P content, and to understand the conversion trend. RESULTS Tillage has the potential to accelerate the processes in transforming macro‐aggregates (> 0.25 mm) into micro‐aggregates (
