Salvaging Immature and Frosted Crops for Silage
Late seeding combined with cool seasonal temperatures delays crop maturity. Frost events in mid-September impact crops, and generally raise concerns about feed options. The severity of frost damage depends on temperature and duration. If a killing frost occurs producers should prepare two plans:
- Late frost scenario
- Early/normal frost scenario
Several crops can be salvaged for silage, including soybeans, sunflowers, canola, corn, and sorghum-sudan grass.
Key Considerations Before Ensiling
- Economic Value: Compare the grain crop’s value to silage potential.
- Harvesting Costs: Assess availability and cost of custom silage harvesters.
- Market Demand: Identify buyers for silage.
- Crop Insurance: Notify and consult Crop Insurance before silaging insured grain crops.
Ensiling Options
- Corn: Common choice for silage when grain harvest is not feasible.
- Soybeans & Sunflowers: Can be ensiled if grain value falls below economic threshold.
- Canola & Sorghum-Sudan Grass: Alternative silage options under late-season conditions.
Use of Preservatives
Preservatives help reduce storage losses from molds and bacteria when ideal fermentation conditions are not met. They are recommended for:
- Crops ensiled at improper moisture levels
- Oilseed crops low in soluble carbohydrates
- Storage systems lacking airtight conditions
Investing in preservatives may be necessary to maintain silage quality.
Weed Control and Safety
Review pesticide application records and consult the Guide to Crop Protection for grazing and feeding restrictions. Always verify compliance before using crops for forage.
Best Practice
Gather all relevant information before proceeding with unfamiliar crops. Proper planning ensures feed quality and minimizes economic losses.
