Fertilizer comes from nature
- Nitrogen fertilizer is made using natural gas and nitrogen from the air.
- Potassium fertilizer comes from salts from evaporated oceans.
- Phosphorus fertilizer comes from fossilized sea remains found in ore deposits.
- Sulfur fertilizer comes from fossil hydrocarbons (often found in areas with high volcanic activity)
These naturally occurring minerals are manufactured into a form that plants can readily use –referred to as “synthetic” or “conventional” fertilizers or nutrients.
Compost and manure are example of “organic” nutrients. Many farmers recycle manure from animal barns or pens to improve their soil.
The “4 R’s”
Farmers are committed to the “4R Nutrient Stewardship” – applying the Right rate at the Right nutrient source at the Right time in the Right place. 4R Nutrient Stewardship is a science-based approach that focuses on increased production, environmental protection and improved sustainability.
