- Association Landscape position affected wheat yield more than nutrient sources or rates.
- Association Fertilizer response was 50 to 300% higher on footslopes than hillslopes.
- Association Soil organic carbon decreased with increasing slope.
- Association Soil clay content decreased with increasing slope.
- Association Soil water content decreased with increasing slope.
- Association Higher nutrient application rates increased differences between landscape positions.
- Association Differences between landscape positions diminished at lower nutrient rates.
