ByoSpxtrum is a water-activated biological powder proven to improve root systems and grow stronger, healthier plants and turf.
ByoSpxtrum contains a variety of beneficial microbes and a patented microbiology strain. Our goal is to combine the best strains so we can utilize their complimentary activities to the utmost benefit. By using combinations of bacteria, ByoSpxtrum has the ability to function in many different ways that are helpful to the plant.
Coverage:
ByoSpxtrum comes in a convenient 17-ounce pouch with a ziplock so it can easily be resealed. One pouch of ByoSpxtrum is enough to treat approximately 5 acres.
Summary:
The strains in ByoSpxtrum are carefully tested and selected based on their abilities. The included microbes outcompete the native microbiology for space and nutrients. They have antimicrobial activity which helps for establishment in the rhizosphere as well as reducing the pathogen levels. ByoSpxtrum’s strains cycle the nutrients found in the soil and solubilize minerals, making them more available for the plant. ByoSpxtrum includes plant growth-promoting strains as well as strains capable of induced systemic resistance (ISR). The product colonizes the plant with beneficial bacteria, suppresses pathogens while feeding the plant, and promotes the growth of the plant. We are able to build all of these activities into a single product by incorporating multiple strains with complimentary activities.

Each strain has been vetted through rigorous testing to ensure its success in the soil profile against naturally present microbes. We select strains that are fast-growing and consume a variety of organic compounds. This includes strains that produce high levels of enzymes, as well as, strains that consume organic acids that are liberated by the plants. ByoSpxtrum also includes strains capable of growing on ammonia, nitrate, and nitrate, making these nitrogen compounds more available to the plant. Each included beneficial bacteria is screened for their ability to do work in the soil and for the plant. For example, these abilities include: growth at different temperatures and different pH extremes, degrade different types of carbohydrates, and produce enzymes. With our bacteria growing in the rhizosphere, we are able to sequester various forms of nitrogen that may have been lost to the atmosphere, such as ammonia. Our bacteria will also grow on the root exudates, in turn producing plant beneficial compounds. As a natural part of the process, our strains will degrade organic matter in the soil, bringing these nutrients into the rhizosphere to help feed the plant. We have also screened our strains for the ability to release nutrients that are tightly bound to the soil for use by the microorganisms and plants, particularly potassium and phosphorous.
ByoSpxtrum is able to inhibit the growth of potential pathogens through induced systemic resistance (ISR). Induced systemic resistance is the addition of bacteria to the root zone to help prevent disease throughout the aerial portions of the plant. The plant is then able to translocate defense signals throughout.
ByoSpxtrum is a variety of microbe food sources designed to enhance the indigenous plant-friendly microbial populations in the soil.

I get great results every time.

Great Product!
Switched from synthetics to an all-organic routine and my yard has never looked better! Mirimichi Green's Carbonizpn-g combined with ByoSpxtrum brought my lawn abundantly back to life. You can literally watch the soil ecosystem hard at work every day. Grateful for these products and can't wait to see how it continues to improve!

This is exactly what I needed to compliment my top dressing of carbonize on, building healthy soil is the key to healthy thick lush turf and having consistent results. Thank you for making such great products for us lawn care fanatics.
Huge improvement with moving to these products on my lawn and landscape areas.
Makes a difference!
Dropping first application of the season this weekend. I am attacking the summer heat here in phoenix with the Mirimichi products for my Burmuda and some of my fruit trees. See how it goes
Root development is essential to healthy turf growth. This is a must have product if you a serious turf hobbyist!
This product is great it mixes well and gives positive results almost instant, will definitely make future purchases
Easy to apply and i definitely saw an improvement in the health of my lawn and soil. thank you for this awesome product!
Using 1000 # of CarbonizPN and a bag of ByoSpxtrum for a treatment on natives grasses in the Colorado mountains.
We did a test of ByoSpxtrum in a standard hydroseeding application on straight sand. Normal spec on both sides, except we added 3.4 ounces of ByoSpxtrum per acre to one side. Can you guess which?
We've been testing ByoSpxtrum and are very impressed with the results. This image shows one plant with no Byo, the middle plant with a half dose, and the largest plant with the recommended full dose of Byo.
I put this sh*# on everything. It's got great coverage so it's an easy mix-in to any of my liquid applications. I use an old jam jar to make my slurry then dump it into my backpack any time I'm spraying nutrients (don't use with pesticides obviously!).
This product has revolutioned our program and offerings at Hippie Fertilizing
Slowing thickening up 13 days post top dressing, more work to do. Bright side is my packages arrived from the #mirimichigreen #golfcourselawnstore Memorial Day Sale. #lawndomination #mclanereelmower #bermudagrass #reelrollers #nwa
