Fertilizer is where most of our crop input money is spent each year. It is easier to waste money and damage the streams by over fertilizing than anything else we do, so it only make sense that I spend more time planning fertilizer rates than anything other input.
- Soil samples are taken according to soil type maps.
- Fertilizer prescriptions are made according to recommended rates for reasonable yield goals.
- Dry fertilizer is applied in late winter or spring rather than fall.
- Enviromental stabilizers and availability aids, like Helena’s Hydra Hume, are used to maximize usage.
- Nitrogen is applied in readily available forms in multiple applications to avoid leaching, denitrification, runoff, and over-application.
- Nitrogen is applied with proper directed nozzles on a sprayer to utilize technology minimizing overlaps.
- Nitrogen is added to irrigated fields through fertigation in 3-6 applications using an Agri-Inject system to minimize leaching while optimizing yield.
- Crushed limestone is applied as-needed to maintain balanced pH levels which minimized the need for high rates of fertilizer.
