Tillage and crop residue management practices on crop productivity, phosphorus uptake and forms in wheat (Triticum aestivum)-based cropping systems*

Conventional tillage, Cropping systems, Crop residue, Grain yield, P fractions, P uptake,Zero tillageIntensive tillage practices are contributing to decliningair, water and soil quality. Reducing soil disturbance byimplementing conservation tillage may improve this situation.Research on zero and minimum tillage has illustrated thegreater opportunity to increase soil organic carbon, microbialactivity, nutrients and extractable phosphorus due toaccumulation of crop residues at the soil surface comparedwith conventional tillage (Vu
