Nutrient deficiency diagnostic training with
field and hydroponically grown crops For fifteen years the Crop Diagnostic School has provided field scouting
and diagnosis training annually for 300-400 agronomists at the University
of Manitoba research station near Carman. For the past 7 years nutrient
depleted sand boxes have been used to display deficiencies of P, K and
S in crops of corn, soybeans, sunflowers, canola, wheat, flax and alfalfa.
Micronutrient deficiencies evaded our best efforts to impose them. In
2010, 4 hydroponic beds were established in the field using silica sand
and with circulation of appropriate nutrient solutions, deficiencies of
Cu, Zn and B were created in wheat, canola, soybeans and dry beans. Participants
at the Crop Diagnostic School earn CCA continuing education credits through
their participation in this lesson and completion of a quiz.
