Organic Fertilizer Guide for Soybeans

No, TNT products are compatible with rhizobium inoculants. In fact, the amino acids in our fish fertilizers can enhance nodulation by providing readily available nutrients that support early root development and bacterial activity.

The R1-R3 stage (flowering to early pod) is most critical. Use TNT HEF 2-3-0 (1 qt/acre) during bloom to support pod set, reduce flower abortion, and improve stress tolerance. TNT HES can also be foliar-applied at 1 gal/acre during vegetative growth for additional nutrition.

For programs targeting root health and resilience under nematode pressure, apply TNT HEF 2-0-0 or TNT HEF 2-3-0 at 3 gal/acre before planting and lightly incorporate into the soil. This supports beneficial soil biology that helps defend against nematode damage.

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.

In 2025 trials with Rise Bio, cooperator Jared Burkeholder documented approximately 97% reduction in soybean cyst nematode counts over 3 years of using TNT HEF — from over 10,000 down to about 300. The 2025 trial used 3 gal HEF + 0.5 gal Super Salmon+ in-furrow and showed visibly superior root mass, vegetative growth, and nodulation in treated plots. Spring 2026 soil counts will confirm whether the SCN suppression effect extends to new fields. This supports the broader finding that TNT products foster disease-suppressive soils.
