The Nutrient Navigator series focuses on efficient, environmentally sound management of nutrients. The goal is to provide practical knowledge that helps drive yields and profits higher.
The 4Rs of Fertility
Focus on fertility to prevent pollution and boost profits
The Challenge of Nitrogen
In your quest for high yields, nothing is more crucial, or more difficult, than managing corn’s most important nutrient
A Moving Target
Preventing corn from going hungry requires balancing nitrogen and other factors, from year to year and field to field
The Great Escape
Stabilizers and controlled-release products help keep the Houdini of nutrients where your crop needs it
In the “Lime” Light
Correct acidity to create diverse microbial populations, which decompose residue and release soil nutrients
Potassium Insight
Drought emphasizes the value of this vital nutrient
Rich in Potassium
The No. 1 challenge with potassium is to manage the nutrient so that it’s ready to work when it’s needed
Potassium Speaks Up
Know how your fertilizer recommendation was calculated to tailor potassium applications to soil type
The Magic of Phosphorus
Understand the cycle to fertilize more efficiently
Field-by-Field Phosphorus
The soil environment tells you when and where to apply this essential nutrient
Just Right Rates for Phosphorus Efficiency
Soil and tissue testing key to phosphorus efficiency
The Fourth Building Block
Sulfur is easily forgotten but essential to high yield
Step-by-Step Sulfur
Application methods, placement and timing depend on soil conditions in each field
The Basics of Zinc
Know where to look for deficiencies to set the stage for preventive management
Don’t Let Zinc Sink Yield
Anticipate deficiencies and then fix them with fertilizer timing and placement
Plants Need Boron to Thrive
It’s likely not the first nutrient you think about, but boron is critical to many plant functions
Target Your Boron Applications
Let your soil and rotation tell you where to expect boron deficiencies
The Role of Manganese
From photosynthesis to building carbohydrates, manganese packs a punch
How to Fix Manganese Problems
Expect to encounter manganese issues on certain soils, plan treatment accordingly
Understanding Iron
Knowledge will help you avoid problems with this vital micronutrient
Manage Iron to Meet Crop Needs
Once you confirm the diagnosis, here’s how to handle iron problems
Two Micronutrients to Watch
Copper and molybdenum are easy to manage if you know how to identify deficiencies
Magnesium Magic
Problems can be avoided, or easily fixed, once you understand this secondary nutrient
