Abstract
A landscape study was conducted near Biggar, Saskatchewan, to study the influence of crop residues on the availability of soil N in the second phase of crop rotations. In order to compare leguminous and cereal residues, chickpea (Cicer arierinum) and wheat (Triricum aestivm) residue were used. The results showed that plant N derived from soil (Ndfs), added nitrogen interaction (ANI) and N recovery from chickpea residue were higher than from wheat residue in footslopes, but not in the shoulders. Chickpea residue increased soil N availability and crop production, whereas wheat residue decreased crop production in the footslopes, but there was no difference between these two residues in the shoulders, indicating that the impact of crop residues was variable and dependent on landscape position.
