Improved Vigor in Citrus, Stone Fruit and Nut Trees
"I’ve always had challenges with my pink grapefruit trees, while my other citrus thrived. After one application of Sustainable Growing Solutions’ MetaGrow F I saw amazing results within weeks. My grapefruit trees now have strong, vibrant green new growth and look fantastic, finally! Highly recommend exploring their products for citrus trees."

“We have been using MetaGrow C for about the last five seasons and has become a key component of our soil biology management program. We grow pears, cherries, peaches and almonds all of which face pressure from pests, disease and other challenges in the central valley. Chitin consuming microbes help shift the soil and canopy biology resulting in the disruption of pathogen cycles. We have seen an improvement of overall plant resilience. If you are looking to build more resilient, biologically active soils I, highly recommend giving MetaGrow C a try as part of an integrated program.”

Vineyard Resilience
“I have been using Metagrow C for many years now in conventional and organic table grape programs, located in the IPM challenging San Joaquin valley. Metagrow C works extremely well and consistently, proactively protecting and sometimes controlling pests and disease using biology. You can work this product in with conventional fungicides or with/replacing costly organic fungicides. It's a unique mode of action that packs a huge bang for your buck. It's worth trying on your crops and seeing for yourself.”

Chile Peppers with large, dense roots and healthy production
Fields of Chile in New Mexico show great vigor and dense root stocks going into the last 5 weeks of the crop season. The field treated with an integrated biological program including SGS MetaGrow, by Rio Gro regenerative agronomists, looks impressive compared to the untreated control.
“We have used MetaGrow 5X+ in multiple programs over the last 2 years, and we've always seen great results. MetaGrow products have the highest POPULATIONS and DIVERSITY of any shelf stable biological I'm aware of. We have seen excellent results with root mass growth, improved plant health (including little to no disease pressure) and excellent regrowth in Chile peppers, as well as biological improvement in soil. MetaGrow 5X+ is a very concentrated product, which makes application much easier on large-scale operations.”

Establishing Healthy Soil with MetaGrow™ F
“Metagrow F is an exceptional product which reestablishes the beneficial fungal communities into your Soil ecosystem. It is both user-friendly and works in a variety of ways and applications. I’ve used this with my clients from peanuts to potatoes, cotton to cover crops and commodities. Tree and vine crops response is even better as they naturally have a greater Fungal relationship.
It’s been applied as a biological seed coat, in-furrow, side dress, foliar, pivots, and by airplane. It is amazing at resetting the system post-harvest, improving nutrient cycling. If you’re growing something other than annuals, you’ll receive an even greater benefits as it allows for more time to build and develop the mycorrhizal relationships in your system.”
Rion Naus, Agronomist
California
“For nearly two decades, I have farmed, managed, and consulted in orchard systems, and more recently, I’ve worked across a wide range of specialty and row crops. Most of my experience with MetaGrow F has been in orchard settings.
Through my various roles, I’ve evaluated and worked with a wide array of biostimulants and biological products. In the end, MetaGrow products — and specifically MetaGrow F — remain my go-to. Biology is foundational to every living farming system, and MetaGrow F stands out for both its diversity (especially its inclusion of fungal species) and its biological density. Again, it is foundational to my biological approach to farming.”
Clayton Handy, Agronomist serving Tree Fruit and Nut Orchards
Corning, California
“MetaGrow F has been a strong addition to our biological program when fungal dominance is the goal. We’ve seen improved residue breakdown, better soil aggregation, and stronger root-to-soil contact over time. It performs especially well in reduced-tillage and regenerative systems where building long-term soil structure and nutrient cycling is a priority.”
Jason Doebelin, Producer of Corn, Soybeans, Wheat

“MetaGrow F is an integral component of our orchard soil and tree health program. SGS provides great customer service for their products. They are an important partner in our overall success in achieving metabolic balance throughout all orchard blocks!”

Transitioning from Conventional to Regenerative Practices
“When it came time to transition our conventional orchard to a regenerative farming system, we needed a big injection of biodiversity to help the soil and trees perform the functions that had previously been deficient, or spoon fed to them. We researched many products to aid in this transition, and ultimately arrived at Metagrow F. We're very happy we did. We performed orchard wide injections, coupled with MFood, from post-harvest through leaf fall. In just a few months we have seen improvements in soil structure, smell, porosity and life. We are excited to see what the new season brings for the crop. Dave and team are a pleasure to work with, and generous with their experienced and logical advice.”
Sean McNamara, Almond Orchardist
Winters, California
“Understanding that most soil systems are highly bacterial, any regenerative practice adoption should consider ways to move the B:F ratio more toward a fungal community. Healthy soils cycle nutrients and residues much more efficiently than bacterial soils. If nothing is balancing out the bacterial population, they will dominate and tie up nutrients within themselves rather than cycle them for the growing crop. Fungi and protozoa are the next level of tropism that are present in a healthy, functioning, breathing soil. MetaGrow F and other products from SGS are the backbone of the products that are blended and sold at Elevate Ag, as we are the Midwest distributor. We are using MetaGrow F in our product line to get the fungal community kickstarted for producers that are wanting to reduce their fertility input costs, and start upcycling the nutrients that are already there. We look for windows of opportunity to get this product in the ground or on residues in the fall. If there is a product with more diversity or higher concentration of beneficial fungi, we have not found it.”

Residue Decomposition
“Game Changer! We have been using this from start to finish (seed treatment, in furrow, foliar, residue management) with amazing and fun results. I have been adding this to our residue management program and shared some photos of MetaGrow F going to work!”

“MetaGrow D-COMP has proven effective at accelerating residue breakdown and organic matter conversion. We’ve seen faster degradation of crop residue and improved nutrient release, helping fields cycle nutrients more efficiently. It’s a solid tool for improving soil function, especially following heavy residue crops.”

Measuring Performance of MetaGrow™ Biologicals
“I have been using Metagrow F for several years now . We have had incredible results when testing our beef and pork for nutrient density . Products truly perform in incredibly tough conditions. Less than 2% OM and 40”+ precip very heavy clay. High levels of a fungal compound ergothionine, a known nutraceutical, are showing up in both beef and pork . Very rare find. Future of food and Ag, highly recommended.”
“I have done side by side trials with 5x+ visual root and plant growth as well as sap test comparison and it has been the lead off in all aspects. Mineral balance on Sap tests had been out of whack and seem to have over time come back into balance without adding any minerals except boron. Glyphosate and AMPA seemed to be broken down as well in our food products after working with the SGS team. There is a lot of synergy in this product .
Chad Meinders, Producer of row crops (Alfalfa, Barley, Buckwheat, Peas, Beans, Flax, Hay and forage grasses, Sorghum and other crops)

“MetaGrow C is truly next level. I’ve been using it in orchards experiencing disease pressure, and the results have been very encouraging. Understanding Chitin and its respective biology and its role in plant health is key — it helps stimulate natural plant defense responses and supports beneficial microbial activity that can suppress disease organisms. I’ve been extremely satisfied with the performance I’ve seen in the field.”

Citrus Grove Restored to Health and Production
A Mandarin orchard in Oroville, California was in bad shape: chlorotic yellowed foliage and not bearing much fruit. They replaced their fertility program with a MetaGrow microbial and fertility program: Four applications of MetaGrow ST, MFood, Bloom Essentials and Synthesis Essentials. Within the same season the foliage looks great and there's a good crop set.
Vince told us: "I just wanted to call and tell you that we've applied your products four times to the soil around the Mandarin trees, and they're now beautifully dark green, not yellow anymore. They are full of fruits and look very healthy. ... we're very pleased with your product and it seems to be doing what it was supposed to do."
