Organic Fertilizer Guide for Corn

The most impactful application windows are: 1) In-furrow at planting (2-4 qt/acre HEF) for root establishment, and 2) V4-V6 stage (2-4 qt/acre) for vegetative growth support. A pre-tassel application provides additional stress protection during critical grain development. Add TNT HES (1-2 qt/acre) plus Molasses (1-2 qt/acre) to any foliar application for enhanced results.

Yes, our products can be applied with most herbicides, pesticides, and fungicides. A bottle (jar) test is recommended to establish compatibility. If applying with a herbicide, utilize TNT HEF 2-0-0 or TNT HEF 2-3-0 as your water conditioner.

Independent trials and customer data show 15-22 bushel per acre improvements with proper application timing. Results vary based on soil conditions, weather, and base fertility program, but most Midwest corn farmers see positive ROI in their first season.

Yes, TNT HEF and our core products are OMRI Listed and approved for certified organic production. Always verify with your certifier, but our products have been used successfully in organic corn operations since 2005.

Independent trials with Rise Bio showed TNT HEF delivered a 15 bu/acre yield increase (238 vs 223 bu/ac) with $147/acre net ROI advantage — combining yield gains with $87/acre input savings by eliminating 60 gallons of 28% nitrogen and Quilt XL fungicide. Microbial diversity increased 420-1,390%, fusarium dropped 78-80%, penicillium dropped 86-92%, and tar spot was found in control plots but NOT in TNT-treated plots. Even the zero-nitrogen trial (HEF + Super Salmon+) was $7/acre ahead of the full conventional program.
