The ®nal surfaces were then calculated with the calibrated coef®cients and the adequacy of the calculated surface to the measured one was evaluated according to: (a) the criterion
In a wet year (year 7), returned-residues incorpo- rated with tillage treatments (either CH or MB) resulted in higher yields than no-residue treatments,- while the residue
To take advantage of conservation tillage systems (including direct drilling and non-inversion) in central Iran, it is important to study the effects of different cultivation
The objectives of our study were: (a) to determine values of the critical water content for compaction and maximum bulk density from Proctor compaction curves for soils different
