Microbes in the Field – Archived 4-2023
The power of beneficial microbes, all season long.
Terrasym microbial inoculants from NewLeaf Symbiotics are a new class of ag biologicals, using pink pigmented facultative methylotrophs (PPFMs) also known as M-trophs, to benefit crops in a multitude of ways from planting to harvest. Pink in color, these naturally occurring microbes are present on virtually all plants around the world and are proven to increase nutrient uptake, improve root mass, and more. Our proprietary Terrasym microbial inoculant technology allows us to selectively add specific PPFM strains to live in true symbiosis with the intended crop, resulting in increased yield and improved ROI.
We believe that by harnessing the power of these naturally occurring PPFM microbial inoculant strains, we are helping growers make agriculture more sustainable by delivering more sustainable products. That’s the promise of Terrasym – Better together.

The science behind Terrasym microbial inoculants.
Our science is powered by our bioinformatics platform, Prescriptive Biologics™ Knowledgebase (PBK), which helps us select and align Terrasym microbial inoculants to a particular crop and environment. This customizability and speed with which we can deliver innovative one-of-a-kind products are exclusive to Terrasym, and we believe the true secrets to its effectiveness.

Terrasym for Soybeans
Terrasym 401
The unique PPFM strain that powers Terrasym 401, Methylobacterium hispanicum, is selected to benefit soybean production and deliver the opportunity to achieve a better and more sustainable yield at harvest. When used as a seed treatment or applied with convenient new planter/hopper box application, growers have seen significant results as a bio-complement to traditional crop protection products.

Terrasym for corn
Terrasym 408
The M-troph at the heart of Terrasym 408 leads to improved early season root development, resulting in enhanced nutrient uptake throughout the growing season. Field trials have shown an 8.9 bushel advantage compared to untreated crops.
Terrasym 408 is applied in-furrow.
Terrasym for corn
Terrasym 450
The early root development and season-long nutrient uptake benefits of Terrasym 408 are now available in a corn seed treatment. Growers have seen higher yields at harvest with Terrasym 450.
Terrasym for Peanuts
Terrasym 402
Terrasym 402 is designed to enhance nutrition uptake by peanut plants during critical stages of development. Terrasym 402, applied in furrow, even fits with other seed treatments, and delivers benefits throughout the growing season.
