JumpStart Delivers More in Canola

Phosphate Fertility in Canola
Ensuring that phosphate is plant-available through-out the growing season is important for high-yielding canola crops, especially hybrids. Because of their small seed size, canola seedlings require assistance from phosphate to advance from germination through to the 3 and 4 leaf stage as the phosphate concentration in the seed can only support seedling growth for approximately a week. But the majority of phosphate is taken up during flowering and pod set.1

Factors limiting P availability in canola:
• Phosphate is immobile in the soil meaning P must be placed within or near the seed row to be available for emerging seedlings.
• Canola is sensitive to seed placed fertilizer – assuming good to excellent soil moisture no more than 20 - 25 lbs/ac of P2O5 should be seed placed.

Phosphate’s importance in canola:
• Phosphate aids in the storage and use of energy developed through photosynthesis.
• Phosphate is essential in the early development of a healthy wellestablished root system.
• Phosphate is essential for early and uniform crop maturity.

Phosphate deficiencies in canola:
• Minor deficiencies include; reduced growth, dark green leaves, poor root development, and spindly branches.
• Severe deficiency symptoms first show up as pink-purple discoloration of the leaf tips and margins of the oldest leaves progressing to bluish-purple discoloration of the leaves and stems.

Top canola growers consistently hit 40 to 50 bushels per acre yet the average yield remains at approximately 25 bushels per acre. To hit those top yields, phosphate fertility is key.

JumpStart Unlocks Canola Potential

JumpStart inoculated canola has more even supply and earlier access to more phosphate without any concerns over seedling safety.
• A uniform canola crop has more potential to withstand weed, insect and disease pressure. Timing of pesticide applications, swathing and crop dry-down is easier to assess with a uniformly developed canola crop.

JumpStart inoculated canola results in more even maturity.
• Late seeding of canola provides quicker more even maturity but is subject to late flowering and delayed maturity that affects crop quality and increases the risk of frost damage.

JumpStart inoculated canola results in earlier maturity.
• JumpStart increases the availability of phosphate from soil and fertilizer phosphate. Enhanced phosphate availability from emergence through to the rosette stage results in increased root growth and increased leaf surface area.
• JumpStart inoculated canola will flower earlier, have an increased number of pod bearing branches, an increased number of pods, more uniform maturity, and earlier maturity so your canola crop can reach its full potential and ultimately achieve higher yields.

Fertilizing JumpStart Treated Canola

JumpStart inoculant is the foundation of the phosphate fertility program, because JumpStart makes much better use of the phosphate fertilizer you apply and makes unavailable forms of soil phosphate immediately available for crop growth.

Adjust soil test recommendations to factor in the impact of JumpStart on availability of phosphate.
