dc.description.abstractThe effect of manure and urea on P availability to canola was investigated under controlled environment condition. Canola (B. napus) was grown in pots with manure and urea added to two Saskatchewan soils (sandy loam and clay loam) at rates equivalent to 0 ( as controls) and 100 mg N/kg. Plants were grown to maturity, and yield and nutrient content determined. Phosphorus supply rates in soils were measured in the pots using anion exchange resin membrane probes. Additions of manure and urea enhanced canola P accumulation and led to a higher P stored in seeds. This response was more evident in the manure treatment. Soil amended with manure significantly increased both N and P supply rates in soils as the manure contains both N and P. On the contrary, application of urea significantly increased N supply rate but led to a slight decrease in soil supply of available P. When fertilizer N was applied, canola maintained its N:P ratio by increasing P adsorption, possibly due to a greater root mass.en_US
