Manage Variability.
- Make the most of every opportunity that good yield environments provide.
- Overcome challenges with site-specific management and improvement.
Input | Site-specific management objective | Soil Role | Factors |
---|---|---|---|
Seed population | Match population to soil’s productive potential | Plant higher populations in more highly productive soil, typically higher water-holding capacity areas with nominal topography. Reduce populations in lower producing areas of problematic soil | Soil EC Soil OM Topography |
Nitrogen | Adjust applied N to account for needs and natural supply through mineralization | Each 1% of organic matter mineralizes 20-30lbs of N during the season. Incorporating this N credit and inherent yield goals allow optimal N rates and timing. | Soil EC Soil OM Topograpy |
Nitrogen | Scout and sample for in-season N loss and post-season carryover | N can be lost through leaching and denitrification. Soil texture and topography are bigger drivers of this extremely mobile nutrient. | Soil EC Topography |
Lime, Gypsum and Sulphur | Adjust pH to ensure maximum nutrient availability. | Identify areas of high & low pH for applying lime, gypsum & Sulphur. | Soil pH |
P, K other nutrients | Determine nutrient needs from soil samples | Choose sample locations based on each area of the field with differing nutrient use, loss and storage potential. | Soil EC Soil OM Topography |
Irrigation water | Optimize soil moisture sensors | Veris maps guide the positioning of soil moisture sensors to ensure that moisture data are representative of the field | Soil EC Soil OM Topography |
Irrigation water | Determine water-holding capacity | Veris maps guide the prescription for the variable-rate pivot to match water rates to soil capacity. | Soil EC Soil OM Topography |
Nematicides | Identify how soil environment affects nematode activity | Veris maps identify areas of increased nematode population | Soil EC Soil pH |
Multi-hybrid/variety | Match the right hybrid and variety to different soils. | Veris maps guide planters equipped to plant different hybrids and varieties. | Soil EC Soil OM Soil pH Topography |
