Cropping systems which conserve soil, water and nutrients are needed on the Canadian prairies. The objectives of this study were: (1) to assess the effects of urea injection on N partitioning in barley-soil systems under conventional (CT) and zero tillage (ZT); and (2) to measure the dynamics of fertilizer and soil N over the growing season. Twelve microplots were installed in each of CT and ZT plots located on a Black Chernozemic soil and were fertilized (59 kg N ha−1) with 15N urea solution, sown to barley (Hordeum vulgare (L.) 'Empress') and destructively sampled at the fifth leaf, ear emergence, grain filling and ripening growth stages. Distribution of 14N and 15N in shoots, roots, mineral N, microbial N, and soil organic N were measured. The recovery of fertilizer N in the soil-plant system was not different between treatments. Microbial N and non-microbial organic N accounted for > 80% of residual 15N in both treatments. Nitrogen budgets showed that grain removal from CT was 76 kg ha−1 and 56 kg ha−1 in ZT. Our study suggests that more 15N from injected urea was converted to organic N under ZT than CT; thus ZT systems have the potential of conserving N. Tillage practices affect the fate of added N.

The Difference

Two cultivars of barley (Hordeum vulgare L.) grown at three levels of soil fertility in lysimeters protected from natural precipitation by an automatic rain shelter were subjected to two levels of soil water stress at heading time. At all levels of fertility, reductions in yield of Compana resulting from stress were proportionately smaller than those of Betzes, but the difference between cultivars was greatest when no fertilizer was applied. This differential response resulted primarily from a substantial decrease in kernel size of Betzes but a slight increase in that of Compana due to soil water stress. The number of tillers and number of kernels per spike of each cultivar were affected about equally.
