FREQUENTLY ASKED QUESTIONS
-
How Does it Work?In much of our landscape, soil disturbances have resulted in degraded lands that are nutrient depleted, allowing invasive undesirable plants to thrive. NutraFix 1-4-1 is a soil amendment that helps to restore the natural, edaphic soil conditions that native plants evolved under. Native plants are “picky eaters”: Native plants evolved in healthy soil conditions that are nutrient dense. Accordingly native plants are more selective in the types and amounts of nutrients they “drink-in” from the soil solution. Native plants are more particular in the amount of micronutrients they absorb and have been observed to thrive under applications of NutraFix 1-4-1. Invasive plants are greedy: Invasive plants, adapted to low-nutrient disturbed soils, are less able to regulate the uptake of additional micronutrients applied. This isn't because the micronutrients are specifically toxic to them, but because they lack the natural mechanisms to regulate nutrien uptake. NutraFix 1-4-1 reestablishes the higher micronutrient fertility levels of late successional grasslands that are resilient and able to discourage weed invasion.
-
What is NutraFix 1-4-1 Made Of?NutraFix 1-4-1 emphasizes micronutrient fertilizers and is produced from naturally occurring minerals from the earth including iron, copper, zinc, boron, manganese.
-
How and When Do You Apply NutraFix 1-4-1?NutraFix 1-4-1 is applied as a granular dry fertilizer using conventional spreaders. The soil fertilizer is best applied in the late summer through the early fall, prior to the period of active plant growth. See detailed application instructions here: How to Apply.
-
How Much Do You Apply?The amount of fertilizer required depends on the density of existing desirable perennial plants found on treatment sites. Lower amounts of NutraFix are recommended for sites with highly desirable plant cover, while higher rates are recommended where desirable plant cover is low. Follow the directions on this page to see general guidelines for application rates
-
How Long Does NutraFix 1-4-1 Last?NutraFix 1-4-1 is slow acting, but long lasting. NutraFix 1-4-1 is a granular soil amendment and can take time to dissolve into the soil solution. Changing the soil chemistry is not a process that occurs overnight. It may take at least one growing season to see effects. The results from one application, however, have been seen to last many years (3 or 5 or even 7 years and counting in some cases!). Some sites may need multiple applications. Retention of soil nutrients is low in soils that are predominantly sand or low in organic matter. Nutrient retention is also governed by climate, soil characteristics, site management, and unplanned disturbances such as wildfire.
-
Why are Grasslands so Important?Grasslands, prairies, or savannas cover 20-40% of the earth’s surface and are endangered by climate change, wildfires, conversion to farming or development, and invasive species.
-
Why Conserve or Restore Grasslands?The wildlife, watersheds, and people that live on the landscapes of the world’s grasslands are dependent on the economic output from rangelands used for livestock production, wildlands that conserve wild birds and animals, and watersheds that serve as sources of drinking water. Our grasslands are at risk of increasing fire frequency, loss of agricultural productivity, losses of wildlife populations, and other hazards.
-
How does NutraFix 1-4-1 Improve Grassland Soil Health?NutraFix 1-4-1 replenishes lost nutrients in degraded soils. Enhancing the soil this way accelerates the growth of perennial vegetation, improves soil structure to promote infiltration, and allows for the growth of deep roots. These conditions increase the organic matter in the soil and allow plants to better withstand drought conditions. Key benefits of NutaFix 1-4-1 include: Biologically rich soil with diverse microbiology Nutrient-dense soil to support microbial life Enhanced nutrient uptake by plants through mycorrhizae and soil fungi Improved soil aggregation for better water infiltration, gas exchange, and root penetration Long term stability and self-regeneration Native seed bank stimulation NutraFix 1-4-1 supports diverse vegetation by discouraging the growth of non-native plants, ensures balanced forage utilization, and facilitates robust nutrient cycling and water retention. It promotes soil health by reducing erosion that can harm soil structure and deplete organic matter and nutrients and avoids the use of petrochemical inputs.
-
How Can NutraFix 1-4-1 Promote Native Plant Growth?NutraFix 1-4-1 is a seed-friendly soil amendment. Based on observations from various test plots, this product appears to stimulate the existing dormant seed bank in the soil, leading to a noticeable increase in native perennial grass diversity, often without the need to reseed. This means that after applying NutraFix 1-4-1, you could see more diverse and robust plant growth on your land, all thanks to the natural seeds already present in the soil. Inside of NutraFix test plot is dominated by western wheatgrass (blueish tone, native perennial grass) without any seeding. The surrounding vegetation is dominated by cheatgrass and mustard.
-
What Do We Mean by Annual and Perennial?Annual and perennial are ways of describing the life cycle of a plant. Annual vegetation germinates, grows, reproduces, and dies in the span of one year. Perennial vegetation grows and lives for three or more years. These terms are important because they help us think about how to approach the management of the vegetation, whether it is annual or perennial. Annual Vegetation: Annual plants can easily turn into invaders with prolific seed production and typical fast growth. This can allow for these invasive annuals to thrive and push out desired plants. For example, cheatgrass is an invasive annual grass that has short, shallow roots. Cheatgrass, among other invasive annual grasses, reduces forage, increases fire risk, and impacts wildlife habitat. Perennial Vegetation: Perennial grasses and forbs can typically have deeper, thicker roots that add organic matter to the soil and allow plants to better withstand drought conditions. These perennial plants help to minimize soil erosion with their deep roots.
-
What are Invasive Plants – How do they differ from Weeds?Invasive plants, unlike weeds, are generally described as those that can successfully establish, become naturalized, and spread to new natural habitats without assistance from humans. These plants are resilient and will grow in places where native and desirable species cannot. Invasive plants have certain characteristics that allow for them to take over, such as rapid growth, continually producing seeds (if conditions permit), high seed output, and high plasticity (meaning the ability of an organism to change in response to stimuli or inputs from the environment).

-
Do livestock and wildlife eat the vegetation on fertilized sites?Oh yes. Anecdotally, both wildlife and livestock appear to prefer the nutrient-dense forage resulting from the NutraFix application.
-
Will NutraFix 1-4-1 Help Reduce Wildfire Hazards?NutraFix 1-4-1 has a strong influence on the growth of perennial grasses that are more fire-resistant and stay green later in the season.
-
What are Micronutrients?Just like for humans, micronutrients are important for healthy plant growth. Later, successional (typically desirable) plants require a proper balance of essential nutrients to thrive. Boron (B) is a trace element that is an important component of plant cell walls, plant growth, pollination, and seed formation. Boron has been cited to have human health benefits in multiple studies. Copper (Cu) is one of eight essential plant micronutrients. Copper is required for many enzymatic activities in plants and is a key element of chlorophyll, playing a vital role in photosynthesis. The human body uses copper to carry out many important functions, including making energy, connective tissues, and blood vessels. Iron (Fe) is involved in many important compounds and physiological processes in plants. Iron is involved in the manufacturing process of chlorophyll, and it is required for certain enzyme functions. Iron is also a mineral that the human body needs for growth and development. Manganese (Mn) is required for photosynthesis, nitrogen metabolism, lignin synthesis, root growth, and activation of many enzymatic systems. Manganese is active in many human health processes such as blood clotting, bone formation, and reproductive health. Zinc (Zn) is an essential micronutrient for plant life. Zinc promotes stronger root development and can help the plant withstand cold temperatures. Most critical of all is zinc’s role in the formation of carbohydrates, proteins, and chlorophyll. Zinc is also involved in many aspects of human metabolism.
