Abstract

Crop residues management is one of the most important factors to sustain agro-ecosystems. Application of plant residues as organic fertilizers has functional role on the amount of soil elements, their availability for crops and finally yield obtained. In order to investigate the effect of different crop residues and their management on providing wheat potassium requirement, a four-replicated field experiment was carried out as a completely randomized block design on wheat (Triticum aestivum L.). Five plant residues with different C:N ratio (including cotton، soybean, alfalfa, wheat and corn) in companion with pure urea and control treatment (without residue or fertilizer) were incorporated as
