“…In zerotillage seeding systems, fertilizer N placement can have a significant impact on crop response. Fertilizer N recovery for barley (Hordeum vulgare L.) was lower when urea was broadcast rather than random banded or side banded, especially when growing conditions were dry (Hartman and Nyborg 1989;Mahli et al 1996).…”

. 2002. Nitrogen fertilizer placement for fall and spring seeded Brassica napus canola. Can. J. Plant Sci. 82: [15][16][17][18][19][20]. Brassica napus L. canola seeded in the fall (dormant) just prior to freeze-up, or in the early spring as soon as fields are passable, can improve productivity in semiarid regions on the Canadian prairies. The objective of this study was to assess N fertilizer placement options for alternative canola seeding dates. Herbicidetolerant B. napus canola (cv. Quest) seedling density, phenological development, seed yield, seed weight, oil concentration, and protein concentration were assessed for four N (urea) placement options [banded prior to fall seeding date (only Melfort), broadcast in early-spring, side banded, and seed placed] and three seeding dates (late October, mid-to late April, and mid-May) at Scott and Melfort, SK, Canada. Nitrogen fertilizer placed with the seed often reduced seedling density. At Melfort, seed placed N fertilizer reduced the seed yield (10%), seed oil concentration (4%) and increased protein concentration (5%) of fall and mid-May seeded canola. The other N fertilizer placement options consistently maintained the highest level of canola production for all seeding dates. At Scott, seeding canola in fall or April generally maintained adequate plant stands, and often increased seed yield (43%), seed weight (18%), and oil concentration (5%), when compared with the mid-May seeding date. Our results indicate that N fertilizer placement considerations used for the more traditional mid-May seeding date should be similar for canola dormant or April seeded. Current N fertilizer placement options, such as side banding, pre-plant banding or early-spring broadcasting, are options that resulted in equivalent crop yield responses. Given the variability in crop yield response measured with seed placement of N, we recommend that this practice should be avoided. ) à l'automne, juste avant le gel, ou au début du printemps, dès que les champs deviennent praticables, on peut améliorer la productivité de cette culture dans les régions semi-arides des Prairies canadiennes. L'étude devait préciser les techniques d'amendement azoté envisageables à d'autres dates de semis. Les auteurs ont évalué la densité de peuplement, la phénologie, le rendement grainier, le poids des semences, la teneur en huile et la concentration de protéines de la variété de canola Quest, tolérante aux désherbants, pour quatre techniques avec de l'urée -application en bande avant les semis automnaux (à Melfort seulement), à la volée au début du printemps, en bandes latérales et directement avec la semence -à trois dates d'ensemencement (fin octobre, du milieu à la fin d'avril et mi-mai), à Scott et à Melfort, en Saskatchewan (Canada). En déposant l'engrais azoté avec la semence, on réduit souvent la densité du peuplement. À Melfort, cette technique a diminué le rendement grainier (10 %) et la teneur en huile des graines (4 %), mais augmenté la concentration de protéines (5 %) du canola semé à l'automne et à...

“…Former experiments on N fertilisers injected in bands focus on the response at maturity, either dry matter yield (Huhtapalo 1982) or 15 N recovery (Malhi et al 1989;Malhi and Nyborg 1991), but during the growing season the plants close to the injected fertiliser bands become greener, indicating an advantage of the applied N earlier than for a larger distance between the fertiliser band and crop plants (Rasmussen et al 1996). The use of injection tools for band application of animal slurry raises the question of the significance of the distance between the slurry band and crop row, particularly during the tillering and elongation phase of small grain cereals characterised by an intensive uptake of applied N (Hartman and Nyborg 1989;Petersen 2001).…”

Crop 15N recovery course affected by spatial distribution of animal slurries in soils

Crop response to applied nitrogen in animal slurry as affected by distribution pattern and slurry type was examined in spring barley using two slurries enriched with isotopic nitrogen ( 15 N). The slurries differing in immobilisation potential were either fully incorporated in the soil or injected in concentrated bands in two fields of low and high fertility caused by the preceding crop. Band-injection of slurry was combined with furrow type formed by different injector tines as well as the distance between the slurry band and seed row. Spring barley was sampled nine times during the season for determination of dry matter (DM) accumulation, total nitrogen (N) uptake and crop recovery of applied nitrogen ( 15 N recovery). A sigmoid growth function was fitted to the recorded crop 15 N recovery. A slurry band to crop row (SB-CR) distance of 4 cm clearly promoted crop 15 N recovery by 6 -12 days and increased total N-uptake and DM accumulation compared with a SB-CR distance of 12 cm. In contrast, the furrow type neither affected the crop 15 N recovery course, total N-uptake, nor DM accumulation. An elevated immobilisation potential in the slurry slowed the 15 N recovery course. In contrast, crop 15 N crop recovery was unaffected by the residual effect of the preceding crop. The elevated immobilisation potential of the slurry also reduced the DM accumulation, but the mineralisation potential of the preceding crop clearly increased total N-uptake and DM accumulation. As the SB-CR distance had a significant effect, this should be taken into account in agroecological systems using application of animal slurry in bands by direct injection.

“…For five irrigation regimes of 0, 10, 15, 20 and 25 mm per week, crop recovery of applied nitrogen increased twofold by banding the fertilizer at 6 cm depth compared with broadcast urea shallow-incorporated at 2 cm depth, particularly in the tillering and stem elongation phases of cereals. Subsurface fertilizer banding also increased grain yield, most significantly at the 0, 10 and 15 mm per week irrigation regimes (Hartman & Nyborg, 1989). Significant yield increases in spring-sown cereals were also obtained with fertilizer placement in dry conditions (Esala & Larpes, 1986).…”

The increasing consumer demand for food products that are produced without the use of pesticides are reflected in action plans to reduce the use of pesticides in agriculture. Most of the barley (Hordeum vulgare L.) produced is used for pig feed but some is used for malting Á the primary step in the production of beer. The effects of fertilizer application method, type and rate on yield and grain quality were investigated in a malting barley crop without the use of pesticides. Twelve treatments, where single and multiple nutrient fertilizers were either broadcast or placed in bands by drilling, were compared in a field experiment at two sites in Denmark during 1993 Á96. Weeds were controlled mechanically in all treatments, and chemical control of foliar fungal diseases and insects was only carried out in two treatments. The placement of a compound NPK-fertilizer increased the grain yield and the quality parameters grain size and grading when weeds are controlled mechanically by harrowing. The effect of fertilizer placement on grain yield and quality decreased in the order NPK /NP /N/P. Herbicide-free growing of malting barley may be possible using fertilizer placement, but the use of chemical control of foliar fungal diseases and insects may be critical when pests exceed certain thresholds as they significantly reduce grain yield, grain size and grading. The aim of growing malting barley satisfactorily without the use of pesticides was only partly met.
