“…Some N uptake was increased by N fertilizer and some available soil N (Nuttall, 1984). Addition of S fertilizer greatly assisted in this process as has been found by others (Bardsley and Jordan, 1957;Cairns and Carson, 19fl;Dijkshoom et a!., 1960;Walker and Bentley, 1961). The additional N uptake because of the application of + 0.…”

“…wh,~n fertilizers are applied to the same stand over a period of years on soils of northern Saskatchewan. Because N to S ratios in herbage tissue have been used as an index of S availability by several researchers (Aulakh et al, 1976;Bardsley and Jordan, 1947;Dijkshoorn et al, 1960;Walker and Bentley, 1961;Westermann, 1975), a comparison of these ratios in relation to soil tests (Nuttall, 1984) might be useful in improving S fertilizer recommendations. The removal ofN, P, and S nutrients from the soil by alfalfa herbage in relation to what is applied by fertilizer may be a useful in<licator of the amount of nutrients required by the plant and that being maintained in the soil.…”

Because N, P, and S fertilizers may be important in the production of high quality alfalfa (Medicago media Pers.) herbage in northern Saskatchewan, concentration of these elements in herbage was measured from experiments with N, P, and S fertilizers applied to alfalfa plots over an extended time period. Nitrogen rates at 10, 45, and 67 kg N ha−1 were applied in combination with 0, 22, and 45 kg S ha−1. Twenty kilograms P ha−1 was applied with these treatments. Other treatments were 10, 0, 0; 10, 10, 0; 22, 0, 26; and 0, 0, 0 (Control); N, P, S ha−1 rates, respectively. In general, first cut alfalfa herbage was lower in protein‐N than the second cut with the exception of 1 year. The lowest N concentration per cut was 33.4 g kg−1 averaged over the life of the stand at the Whitefox site (Wf fsl, Whitefox fine sandy loam, Typic Cryoboralf). The highest N concentration in herbage per cut was 39.7 g kg−1 at the Waitville site (Wv 1, Waitville loam, Typic Cryoboralf). Only at the Wv 1 site, and only with S fertilizer, was N concentration consistently increased every year (after establishment year). The percentage of applied N recovered in the alfalfa ranged from 48 to 95%. Approximately 14 kg S ha−1 per year (two cuts) was removed by herbage when fertilized at 22 kg S ha−1 at the Wv 1 site. At a fertilizer rate of 45 kg S ha−1, uptake of P per year (two cuts) was approximately 19.0 kg P ha−1. The lowest yield of N was 78 kg N ha−1 per cut at the Wv 1 site averaged over the life of the stand. The highest uptake was 128 kg N ha−1 per cut at the Melfort soil site (M sic, Melfort silty clay, Typic Cryoboroll). A range of 14:1 to 21:1 of the N to S ratio in herbage was the limit indicated for a S deficiency in the alfalfa crop. Plant testing could be used in conjunction with the soil test for S in making fertilizer recommendations.

“…The small response of aspen seedling growth rates to S application indicates that the two aspens were not very sensitive to S availability, perhaps because of a low S requirement by the two aspens. In agronomic crops, S appeared to be more deficient than P in those types of soils (Newton 1936;Walker and Bentley 1961). Our data set shows that when S was applied together with P, the effects were greater than if S was applied alone for most of the measured growth parameters.…”

“…Earlier studies have shown that Luvisolic soils are deficient in P and S needed for the growth of various plant species (e.g., Newton 1936;Walker and Bentley 1961;Toogood et al 1962). Earlier research on the nutrition of poplar and aspen species had focused on N, P, and micronutrients and had shown strong growth response to N, P, or other nutrient additions at planting (Heilman and Xie 1993;van den Driessche 1999;Brown and van den Driessche 2002).…”

A greenhouse experiment was conducted to investigate the effects of P and S fertilization on the growth and nutrition of two aspens, a clonal aspen (Populus tremuloides Michx.) and a hybrid aspen (a mixture of Populus tremuloides × P. tremula L. and Populus tremula × P. tremuloides), grown in a Gray Luvisol fertilized with N. Phosphorus application significantly increased basal diameter (BD) increment and most other growth parameters for both clonal and hybrid aspens, whereas S application increased BD increment only for the hybrid aspen. Diameter increment, leaf area, and seedling biomass were generally increased by P application, regardless of S levels, but they responded to S application only if P was also applied. Phosphorus application significantly increased foliar P concentrations and foliar N and P contents and their uptake for the clonal aspen. For the hybrid aspen, P application increased foliar N, P, and S concentrations, contents, and uptake. Sulfur application significantly increased foliar S concentration, content, and uptake for the hybrid aspen but not foliar N concentration, content, and uptake for the clonal aspen. Except for height increment, growth parameters were significantly related to foliar percent P and N/P ratios and percent S and N/S ratios. It can be concluded that both P and S were deficient, but P was more limiting after potential N limitation was removed.Résumé : Une expérience en serre a été réalisée dans le but d'étudier les effets d'un apport de P et S sur la croissance et la nutrition de deux sortes de peuplier, un peuplier clonal (Populus tremuloides Michx.) et un peuplier hybride (un mélange de Populus tremuloides × P. tremula L. et de Populus tremula × P. tremuloides), cultivés dans un luvisol gris fertilisé avec N. L'application de P a significativement augmenté l'accroissement en diamètre à la base et la plupart des autres paramètres de croissance, tant chez le peuplier clonal qu'hybride, tandis que l'application de S a favorisé l'accroissement du diamètre à la base seulement chez le peuplier hybride. La croissance en diamètre, la surface foliaire et la biomasse des semis ont généralement réagi positivement à l'application de P indépendamment du niveau de S mais elles ont réagi à l'application de S seulement si P était aussi appliqué. L'application de P a significativement augmenté la concentration foliaire de P et le contenu en N et P dans le feuillage ainsi que le prélèvement de ces nutriments chez le peuplier clonal. Dans le cas du peuplier hybride, l'application de P a augmenté la concentration foliaire de N, P et S, leur contenu et leur prélèvement. L'application de S a significativement augmenté la concentration foliaire, le contenu et le prélèvement de S chez le peuplier hybride mais pas ceux de N chez le peuplier clonal. À l'exception de l'accroissement en hauteur, les paramètres de croissance étaient significativement reliés au rapport N:P et à la proportion de P ainsi qu'au rapport N:S et à la proportion de S dans les feuilles. On peut conclure que P et S étaient...

Both soil and plant analysis are diagnostic tools used in identifying S deficiencies; however, soil tests evaluating soil S availability levels are not always successful and deficiencies must then be identified by plant analysis. In addition, the diagnostic tool must be correlated to crop responses under various growing conditions to be useful. Identification of S deficiency on alfalfa (Medinago saliva L) in southern Idaho permitted the collection of correlation data for both S soil tests and plant analyses. The S soil test correlation data has been previously reported (Aron. J. 66:578 .581, 1974). This paper reports the relationships found between the plant S indexes of total 5, S0,-.5 and total (N/S) ratio, and the response of alfalfa to S fertilization. All data were evaluated by correlation analyses.The total S and SOeS concentrations and the total (N/S) ratio were all found to be satisfactory indexes of S deficiency in whole alfalfa at early bloom. Maximum forage yields were obtained when the tops contained between 0.15 to 0.20% 5 or 0.05% S0,-S. Total S and 50,-5 were related and readily interchangeable as indexes. Increases in total S above 4.14% S resulted from the accumulation of S0,•S. Yield responses to S fertiliza-• tion were obtained when the total (N/S) ratio was greater than 17 to 18. Total N and total S were not related, but protein N increased linearly as protein S increased. The protein (N/S) ratios were not constant and increased from 17 to 23 as the degree of S deficiency increased. Additional index words:Total 5, S0,-5, Total (N/S), Protein (N/S), Lucerne, Medicago sativa L.
