Big Foot Root Boost Nitrogen-Fixing Azospirillum | 32oz

Nitrogen-Fixing Bacteria Drench for Root Zone Nutrient Uptake, 32oz

Nitrogen already in the soil isn't always in a form roots can use efficiently, which can leave plants nitrogen-hungry even when fertility levels look adequate on paper. Big Foot Root Boost is built on Azospirillum brasilense, an all-natural, nitrogen-fixing beneficial bacteria that colonizes the root zone and helps plants take up nitrogen more efficiently.

This 32oz size suits growers who want a season-long supply for repeated applications across multiple plantings.

Who Should Use Big Foot Root Boost

About Big Foot Mycorrhizae

The American Root Company, maker of Big Foot Root Boost, was founded in 2016 by Zack Amaranthus. Its formulas draw on the mycorrhizal fungi research of his father, Dr. Mike Amaranthus, a scientist who has studied root symbiosis for more than 30 years — a research legacy the younger company was built to commercialize.

Frequently Asked Questions

What is Azospirillum brasilense?

It's an all-natural, nitrogen-fixing beneficial bacteria that colonizes plant root zones and supports more efficient nitrogen uptake. It occurs naturally in soil and is concentrated here for direct application.

How is this product applied?

Mix the liquid into water and apply it as a drench at the root zone, either at planting and transplanting or during routine watering. Consistent application gives the bacteria the best chance to establish around developing roots.

When should I apply it?

Apply at planting, transplanting, or during routine watering throughout the season. Earlier application gives the bacteria more time to establish alongside developing roots.
