“…In earlier research in Saskatchewan, Malhi et al (2002) observed the accumulation of nitrate-N in soil under organic input (i.e., no input of fertilizer), more so in some cases than in soil receiving adequate amounts of both N and P fertilizers due to relatively low plant-available P in soil for optimum crop growth under organic input. Similarly, in the present study the greater amount of nitrate-N in soil in the N-only plots, compared with N' S fertilizer plots, was most likely due to poor crop growth and N-use efficiency of applied N in the N treatment without applied S in this extremely S-deficient soil.…”

. 2009. Influence of six successive annual applications of sulphur fertilizers on wheat in a wheat Á canola rotation on a sulphur-deficient soil. Can. J. Plant Sci. 89: 629Á644. A 9-yr (1999Á2007) field experiment was conducted on a S-deficient Gray Luvisol (Typic Cryoboralf) loam soil at Porcupine Plain in northeastern Saskatchewan. The objective was to compare the influence of six successive annual applications (1999Á2004) and the following residual effects for 3 yr (2005Á2007) of elemental S and sulphate-S fertilizers on yield, seed protein and total S concentration, and S uptake of wheat (Triticum aestivum L.) in a wheatÁcanola rotation. Treatments used were combinations of two application times (preceding autumn and before seeding in spring) with two granular elemental S fertilizers (ES-90 and ES-95), one fertilizer containing both elemental S and sulphate-S (Agrium Plus), ammonium sulphate, and a zero-S control. The S fertilizers were applied annually at a rate of 15 kg S ha (1 . From 1999 to 2004, seed yield (3 yr) and straw yield (4 yr), seed protein concentration (3 yr), total S concentration in seed (4 yr), and S uptake in seed (5 yr) and straw (5 yr) of wheat showed significant response to S fertilization. In the first year (1999), ammonium sulphate and Agrium Plus were more effective than ES-90 and ES-95. In the following years (2000Á2004), there was no significant effect of S source on seed and straw yield. Sulphate-S containing fertilizers produced greater total S concentration in seed and S uptake in straw (3 yr) and for S uptake in seed (1 yr). There was no effect of timing of S application on seed yield and protein concentration in any year, but autumn application was superior to spring application for straw yield and S uptake (1 yr), and for seed total S concentration and S uptake (2 yr). Residual effects of six previous S applications showed improvement in wheat seed yield until 2006, and straw yield and total S uptake until 2007. Elemental S, especially when applied in autumn, tended to have more lasting residual effects than the other S fertilizer treatments. There was some build-up of residual sulphate-S in soil in almost all S fertilizer treatments after four successive applications, but this was generally higher with sulphate-S-containing fertilizers. Recovery of applied S from 1999 to 2004 in plants was usually higher with sulphate-S fertilizer than with elemental S fertilizer in most years. Recovery of applied S in soil was higher for sulphate-S fertilizers, followed by ES-90, and finally ES-95. Residual nitrate-N in soil was significantly lower in spring-applied ammonium sulphate treatment than the zero-S or other S treatments.Key words: Elemental S, fertilizer, protein concentration, S uptake, sulphate-S, wheat, yield Malhi, S.

“…The amount of nitrate accumulated in soil profiles under faba bean was similar to or even less than those under wheat. Malhi et al (2002) found that cropping systems could influence the accumulation and distribution of plant nutrients in the soil profile, especially for nitrate N. In low cropping diversity where crop sequence was fallow or green manure-wheatwheat-fallow or green manure-canola-wheat for 6 years, there was a greater nitrate-N accumulation compared to diversified annual grains where crop rotation was lentils (green manure) fallow-wheat-field pea-barley-sweet clover (Malhi et al, 2002). Previous results of the same experiment (Li et al, 2003b) showed that N uptake was increased to 152-175 kg ha À1 for intercropped wheat from 79 to 115 kg ha À1 for monocropping wheat at different N rates of application.…”

“…Previous studies have shown significant increases in residual nitrate-N in soil after long-term applications of N fertilizer, especially at high N rates (Malhi et al, 1991(Malhi et al, , 2002(Malhi et al, , 2009Guillard et al, 1995). Similarly, in our study, there was an increase in residual nitrate-N in the 0-20 cm soil depth due to N fertilization, but the amounts were relatively small particularly at Breton, even after 32 annual applications of N fertilizer, as also suggested in our previous report .…”

The effects of short-term (4 years) tillage (hereafter called reverse tillage [RT]) of land previously under long-term (29 or 30 years) no-till (NT), with straw management (straw removed [SRem] and straw retained [SRet]) and N fertilizer rate (0, 50 and 100 kg N ha There was no significant effect of RT and straw on ammonium-N, nitrate-N and extractable P in soil. Ammonium-N in soil increased significantly (but small) with N rate in many cases at both sites. Nitrate-N in soil increased with increasing N rate from 0 to 100 kg N ha at Ellerslie. In summary, increased N fertilizer rates were usually associated with decreased extractable P and increased nitrate-N in soil, but RT and straw had no effect on these nutrients in soil.
