Review past deficiency symptoms
and other growth problems
Define all yield limiting factors
from last year's crop
Correct soil pH as needed
Consider insect, weed, and soil
compaction potentials
Know
the Plant Nutrients
Primary nutrients: Nitrogen,
phosphorus and potassium (used in the largest quantities
by plants)
Secondary nutrients: Magnesium and sulfur
(calcium can sometimes be important as a nutrition problem)
Micronutrients: Nutrients used in very
small quantities, such as boron, manganese and zinc,
may need attention. Other micronutrients (iron, copper,
chloride, and molybdenum) require attention in some instances.
Evaluate management decisions and inputs that can be improved
or changed
Start a 3-5 year yield improvement program with a goal to
improve yields 10-20 percent per year
Options
For Starter Fertilizer
Methods of application
and placement should be considered
Starter band placement may provide
benefits in cool, wet springs, low fertility situations, early planting
and other high stress situations
The "starter effect" generally
disappears during the growing season in high fertility fields
Consult
Local Fertility Experts
Many factors influence
crop response to fertilizers. Local crop advisors, such as your fertilizer
dealer, independent crop consultant, county agent or other supplier
advisors, can provide invaluable advice when making fertilization decisions.
Finalize
Nutrient Management Plans
After considering all
factors, the nutrient management plan should include the quantity, placement
and timing of nutrient applications
It is a Best Management Practice to
ensure adequate but not excessive nutrients are available to the growing
crop
Develop a plan to achieve production
and environmental goals
