Early supplies of available nitrogen to the seed-row as affected by fertilizer placement
Thavarajah, D.; Schoenau, J.J.; Bettany, J.R.; Hultgreen, G.; Qian, P.; Malhi, S.S.; Lemke, R. (2001-02-22)A field experiment was conducted at Star City, (legal location SW6-45-16-W2); Saskatchewan, Canada from May to June 2000, to measure N and P supply rates from fertilizer band to canola seed row. Ion exchange resin membrane ... -
Effect of cultivation, tillage practice, and fertilization on total organic carbon, light fraction, and microbial biomass carbon in soils from the Loess Plateau of China and the Canadian prairies
Wu, T.; Schoenau, J.J.; Li, F.; Qian, P.; Malhi, S.S.; Shi, Y. (2002-02-20)Three soils: Huangmian, Huihe, Heilu soil, from the Loess Plateau and one soil: Orthic Brown Chernozem, from the Canadian Prairies, were used to evaluate the effect of cultivation time, tillage system and fertilization, ... -
Effect of hog manure on soil phosphorus forms
Qian, P.; Schoenau, J.J. (2000-02-22)Application of livestock manure can benefit crop production as a valuable source of nitrogen (Bandel and Fox 1984; Campbell et al. 1986; Chase et al. 1991). However, phosphorus is not a negligible factor as phosphorus in ... -
Effect of seed-placed ammonium sulfate and monoammonium phosphate on germination and emergence of canola
Urton, R.; Qian, P.; King, T.; Schoenau, J.J.; Fatteicher, C.; Grant, C.A. (2011-03-15) -
The effect of seed-row placed controlled-release P (CRP) fertilizer on crop emergence under controlled environment conditions
Qian, P.; Schoenau, J.J.; King, T.; Fatteicher, C. (2006-03-02) -
Effect of soil amendment with alfalfa pellets and glycerol on nutrition and growth of wheat
Qian, P.; Schoenau, J.J.; King, T.; Fatteicher, C. (2008-02-28)Two pot experiments were carried out under controlled environment conditions in the laboratory. One was to assess the ability of alfalfa pellets to supply plant available N as an organic fertilizer. The other was to ... -
Effect of soil amendment with dry and wet distillers grains on growth of canola and soil properties
Qian, P.; Schoenau, J.J.; King, T.; Fatteicher, C. (2009-02-25)Controlled environment experiments were set up to evaluate the effect of applying distillers grains to soil as organic amendments to increase soil fertility, crop growth and soil organic matter. The two distiller grains ... -
Estimating nutrient release from soil organic matter using ion-exchange membranes
Qian, P.; Schoenau, J.J.; Braul, A. (1993-02-25)A simple method was developed to assess mineralizable soil organic N and S using anion-exchange membrane (AEM) burial. With this method, strips of AEM were buried in the soil and used to absorb nitrate and sulfate ions ... -
Evaluation of nitrogen availability from different manure amendments with different C:N ratios
Qian, P.; Schoenau, J.J. (2001-02-22)A growth chamber study was conducted on two Saskatchewan soils to assess the effect of application of different types of animal manure with different C:N ratios on canola yield and nitrogen uptake. Treatments consisted of ... -

Schoenau, J.J.; Charles, J.; Went, G.; Qian, P.; Hultgreen, G. (1999-02-25)Experiments were conducted in 1997 at two sites (Burr and Dixon) in the Black soil zone, east - central Saskatchewan, to examine the effects of different rates and methods of application of swine and cattle manure applied ... -
Impact of repeated addition of swine manure and cattle manure on Cu and Zn amount and distribution in a Saskatchewan soil
Qian, P.; Schoenau, J.J.; Wu, T.; Mooleki, P. (2003-02-18)Increasing use of animal manures in Saskatchewan requires information on the fate and distribution of residual manure copper (Cu) and zinc (Zn) in Saskatchewan soils. To address this issue, the amounts of soil Cu and Zn ... -
