Assessing Nutrient Content of Crops and Nutrient Removal as Affected by Management Practices
A study to identify mineral nutrient removal in the harvested portion of crops grown in western Canada.
IPNI-2001-CAN-MB14
10 Apr 2001
Methodology
- These goals will be addressed by a combination of analysis of stored samples from studies conducted at a range of sites in western Canada, analysis of samples from studies being conducted currently, where funds are not available for complete nutrient analysis, and conduct of new studies directed to fill information gaps not addressed in previous research. Utilizing stored samples and on-going studies allows us to collect a large database quickly, without having to invest in additional resources to "reinvent the wheel".
Analysis of samples from established on-going studies
Samples from the following on-going studies will be analyzed for micro- and macro-nutrient content:
a) Influence of P fertilizer level on HRS wheat grown under zero- and conventional tillage management (4 year study initiated in 1999 - 3 P rates x 2 tillage systems x 4 reps x 2 locations = 48 samples per year).
b) Comparison of organic, totally pesticide-free, integrated pest management and conventional rotations, including field pea, durum wheat, flax and oat (4 phase x 4 treatment x 4 rep x 2 location = 128 plots).
