Cover Crop Value Calculator
Compare the nutrient and economic value of cover crops versus synthetic fertilizers
Input Your Information
About This Tool
This calculator helps farmers compare the economic value of planting cover crops versus using synthetic fertilizers based on nutrient content and additional soil benefits.
How it works:
- Enter your field size and cover crop information
- Input current fertilizer costs for N, P, and K
- See the calculated nutrient value and economic comparison
Note: Actual results may vary based on your specific soil conditions, climate, and management practices.

Cover Crops vs. Synthetic Fertilizers
Cover crops are plants grown primarily to benefit the soil rather than for harvest. They offer several advantages over synthetic fertilizers:
Cover Crop Benefits
- Natural nutrient cycling
- Improved soil structure
- Erosion control
- Weed suppression
- Increased soil organic matter
- Enhanced water management
Synthetic Fertilizer Drawbacks
- Higher input costs
- Potential nutrient runoff
- No added soil structure benefits
- Fossil fuel dependencies
- Doesn't improve soil biology
- Price volatility
Understanding Cover Crops
What are cover crops?
Cover crops are plants grown primarily for the benefit of the soil rather than for harvest. They protect soil from erosion, improve soil health, enhance water availability, smother weeds, help control pests and diseases, and increase biodiversity.
Common types of cover crops:
- Legumes (clover, vetch, peas): Fix nitrogen from the air
- Grasses (rye, oats): Prevent erosion, add organic matter
- Brassicas (radish, mustard): Break up compacted soils
- Mixtures: Combine benefits of multiple cover crop types
Benefits beyond nutrients:
- Soil structure improvement: Cover crop roots create channels for water and air
- Erosion reduction: Plants and roots hold soil in place
- Weed suppression: Competing with weeds for resources
- Pest management: Breaking pest cycles
- Carbon sequestration: Capturing carbon in soil organic matter
- Water quality: Reducing runoff and nutrient leaching
