How It Works

Culbac Fertilizer Adjuvant works in harmony with your fertilizer to activate the soil microbiome and stimulate plant vitality. The result? More efficient nutrient use, stronger root systems, and improved tolerance to stress — all translating to a healthier, more productive crop. On top of that, you can use 10% less fertilizer starting with the first application, 25% less fertilizer in year two of use, and 50% less fertilizer in year three of use while still seeing the same or better crop yields. The return on investment is clear….and significant! Particularly with today’s fertilizer costs!
