“…Dispersion of an elemental S prill followed by mixing (incorporation) into soil was reported to enhance oxidation and availability (Swan et al 1986). This can be obtained by surface-broadcast application of elemental S in the previous autumn leaving granules on surface to physically break down over the winter by freezing-thawing and wetting-drying cycles, followed by shallow cultivation to incorporate fine S particles into the soil in the following spring to increase their dispersion into soil prior to seeding (Nyborg et al 1980;Solberg et al 2003).…”

. 2005. A review of sulphur fertilizer management for optimum yield and quality of canola in the Canadian Great Plains. Can. J. Plant Sci. 85: 297-307. In the Parkland region of the Canadian prairies, Canola (Brassica napus L. or Brassica rapa L.) is an important cash crop. Canola has a high requirement for sulphur (S). However, many soils in this region are deficient or potentially deficient in plant-available S for optimum canola seed yield. Application of sulphate-S at about 15-30 kg S ha -1 is usually sufficient to prevent S deficiency in canola on most of the S-deficient soils. Application of sulphate-S to canola at seeding time gives the highest increase in yield and S uptake. Deficiencies of S in canola plants can be prevented and/or corrected and seed yield improved with the use of sulphate-S fertilizers in the growing season. Application of sulphate-S at bolting can substantially restore seed yield, while an application at early flowering can moderately correct S deficiency damage. Side-banding is the most effective way to apply sulphate-S fertilizers to produce maximum seed yield and to prevent any damage to canola seedlings from seed-row placement. In relatively moist areas, broadcast-incorporation methods can produce seed yield similar to side-banding in most years.Elemental S fertilizers were not effective in increasing seed yield in the year of application, and were generally less effective than sulphate-S fertilizer even after multiyear annual applications, especially when applied in spring. Autumn-applied elemental S was more effective than spring-applied elemental S. Banding delayed availability of elemental S as compared to broadcast application. Use of granular elemental S products is not reliable for optimum seed yield of canola under Canadian prairie conditions on S-deficient soils, particularly in the initial year and with spring application or band placement. Elemental S fertilizers may have a role to maintain or build-up sulphate-S levels in soils marginally low in S where residual benefits are desirable, but management decisions should consider both immediate and long-term effects of S fertilizer on seed yield, seed quality and economics. The findings suggest the need of future research to increase dispersion and distribution of S particles from granules for faster oxidation of elemental S in soil, and to develop elemental S fertilizer products/formulations that can be used on a commercial scale to prevent and/or correct S deficiency in the growing season to optimize seed yield and quality of canola. Research is also required to determine the long-term effects of balanced application of S with other nutrients on soil quality, accumulation and distribution of nitrate-N, sulphate-S and other nutrients in the soil profile, efficiency of nutrient, water and energy use, and crop diseases. More research should be conducted in relation to soil/plant tissue testing issues for optimum seed yield and quality of canola.Key words: Balanced fertilization, canola, elemental S fertilizers, method of ap...

“…Very low recovery from banded and nested than incorporated Flowable S and Fine S was considered to be the result of a decrease in surface area exposed to soil. Other researchers also have shown much higher oxidation rates when elemental S was mixed into soil rather than banded (Chein, Friesen, and Hamilton 1988;Swan, Soper, and Morden 1986). Generally smaller recovery from nested than banded S (Table 6) could also be explained by further reduction in exposure of surface in nested S. Significantly more recovery from banded Flowable S than Fine S (Table 5), although both showed similar recovery with incorporation, was likely due to a relatively wider band (8 mm) for Flowable S compared to a narrower band (4 -5 mm) for Fine S. Although broadcasting of Flowable S reduced the recovery compared with incorporation, it still gave high recovery (Table 6).…”

“…The "right" time to apply S-containing fertilizers is considered to be the sowing period, which ensures maximum canola yield [77]. A more appropriate approach for applying S-SO 2− 4 fertilizers is side-banding, and for S 0 fertilizer is broadcast-incorporation [18,78]. Notably, "right" and long-term S fertilization in S-deficient soils can increase soil carbon sequestration [79], which is important for sustainable use of agricultural land.…”

Soil Sulfur Deficiency Restricts Canola (Brassica napus) Productivity in Northwestern Russia Regardless of NPK Fertilization Level

Canola cultivation at high latitudes is becoming more promising in terms of modern climate change. Sustainable crop production requires an understanding of yield-limiting factors, which need to be adjusted in agricultural management first. Therefore, our study was aimed at examining the effect of climate and soil fertility factors on the canola yield from 2012 to 2015 in northwestern Russia. Simultaneously, effectiveness of chemical fertilizer (N65P50K50 and N100P75K75) rates was tested. Studied soils had light texture, high acidity and severe sulfur deficiency. Canola yield (Y) varied from 0.81 to 1.60 t·ha−1 for the observed period. Applied fertilizer increased Y by around 30%, but this change was not significant. Climate effect testing with the FAO-AquaCrop simulation showed no noticeable water and heat stresses for the study period (0% to 20% reduction in potential Y). Among the tested soil properties, the content of organic carbon, available nitrogen and sulfur significantly correlated with Y (r = 0.58–0.66). Combining these factors together with soil pH in a path model explained 60% of variability in Y. Importantly, sulfur had the highest and most significant effect in this model. Thus, this soil parameter is the main yield-limiting factor in the study area, which must be the first to be adjusted in agricultural practice.
