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
