Compare Nitrogen Sources

Looking for a concentrated nitrogen source? Explore Organic Blood Meal 13.6-0-0 (50 lb) or Organic Feather Meal 12.8-0-0 (50 lb). For another meal option, browse Cottonseed Meal (5 lb Box). Compare package sizes, ingredients and label instructions before choosing the right nitrogen fertilizer for your planting area.

For a blended option, consider Phyta-Grow Leafy Green Special Fertilizer 7-1-2 (5 lb bag). Shopping for lawn nutrition? Compare Bio-Turf 8-3-5 Fertilizer (4 lb Box) with your soil test recommendations and turf needs.

How to Choose

Use soil or tissue testing when possible. Match nitrogen concentration and application rate to the crop, growth stage and existing fertility. Review each product's intended uses, application methods and timing rather than choosing by nitrogen percentage alone. Follow label directions to reduce overapplication and nutrient loss, and account for nutrients supplied by compost or other fertilizers.

Complete Your Fertility Program

Browse all-purpose fertilizers for additional blended options, explore liquid fertilizers for your preferred application method, or compare products in our nutrient-specific collection. Select the analysis and package size that suit your growing space, then shop nitrogen fertilizers at Grow Organic to build a practical plant nutrition program for the season ahead.
