Guide to Transitioning into Regenerative Farming

March 24, 2026

Transitioning into regenerative farming is not about flipping a switch overnight. It is about creating an on-ramp for soil biology while gradually building an off-ramp away from heavy reliance on synthetic inputs. When done correctly, this approach leads to healthier soils, more efficient nutrient use, and stronger crop performance over time.

In this guide, we will use corn as an example, but these principles can be applied across many crop systems with the right adjustments.

Biology vs. Chemistry in Regenerative Agriculture

At its core, regenerative farming focuses on feeding the soil biology rather than just the plant. One of the biggest challenges growers face is that conventional, water-soluble fertilizers can suppress microbial life in the soil.

Every time a highly soluble fertilizer is applied, it can reduce microbial activity, which limits the soil’s natural ability to cycle nutrients. Because of this, growers must “earn the right” to reduce nitrogen and other inputs by first rebuilding biological activity.

The On-Ramp for Soil Biology

This is the first step into your regenerative agriculture journey; developing a natural soil ecosystem that begins producing nutrients without the need for fertilizers. 

Fall Applications Build a Strong Foundation

One of the most effective ways to build soil biology is through fall applications of microbial inoculants. Applying these products in the presence of living roots allows microbes to establish and multiply before winter sets in.

Cooler soil temperatures create an ideal environment for microbial populations to expand. By spring, this results in a stronger, more active biological system capable of releasing nutrients when crops need them most. While spring applications still provide value, fall applications tend to move the needle further in terms of long-term soil health.

Products like Root Primer, BioQuest Foundation, and EnSoil Algae are commonly used to help establish this biological foundation.

Seed Inoculation at Planting

Another critical step is inoculating seeds with beneficial microbes at planting. This ensures that the root system is colonized immediately after germination, setting the stage for strong early growth.

Applying a product like BioQuest Magnifier directly to the seed is a low-cost, high-return investment. It supports early root development and helps establish a thriving microbial environment right from the start.

The Off-Ramp for Soluble Fertilizers

In a perfect world we could just cut out all of the bad, and insert all the good, but doing things the right way takes time, and there is a proper order to make sure we ween off fertilizers properly, and supplement accordingly. 

Why Reducing Soluble Inputs Takes Time

Soluble fertilizers can be harsh on soil biology, but eliminating them too quickly can negatively impact yields, especially in soils that are heavily dependent on them. The goal is not to remove them all at once, but to gradually reduce their use as soil biology improves.

This transition involves applying less fertilizer upfront, stabilizing what is applied, and shifting more applications to foliar feeding where appropriate.

Rethinking Nitrogen Efficiency

Conventional thinking suggests that it takes about one pound of nitrogen to produce one bushel of corn. However, many growers have successfully reduced that number significantly by improving nitrogen efficiency through biology.

There are cases where growers are producing strong yields with half a pound of nitrogen per bushel, while also improving grain quality and protein content. This highlights the importance of focusing on efficiency rather than total input.

A Practical Nitrogen Management Strategy for Corn

For growers currently applying around 200 units of nitrogen and achieving 150 to 170 bushels per acre, a transition plan might involve reducing total nitrogen to around 100 units and splitting applications throughout the season.

Application 1: At Planting

Apply approximately 40 units of nitrogen at or just before planting. It is important to avoid placing nitrogen directly in the seed zone. A minimum 2×2 placement helps protect early microbial colonization and root development.

At this stage, nitrogen in ammonium or nitrate form helps stimulate plant hormones such as auxins, cytokinins, and gibberellins, which promote strong root and shoot growth.

To improve efficiency, nitrogen should be stabilized. This can be done by adding ammonium thiosulfate to achieve a nitrogen-to-sulfur ratio of at least 10 to 1, along with humic substances and a small amount of molybdenum. This approach encourages nitrogen to be held within microbial biomass rather than being lost through leaching.

Application 2: Side Dress

A second application of 40 units of nitrogen can be applied as a side dress using a similar stabilized approach. This ensures continued nutrient availability during key growth stages without overwhelming the soil system.

Applications 3 and 4: Foliar Feeding

The remaining nitrogen can be applied through two foliar applications of approximately 10 units each using low-biuret urea.

Foliar nitrogen is significantly more efficient than soil-applied nitrogen. Research and field experience suggest that one pound of foliar-applied urea can provide a yield response similar to four to seven pounds of soil-applied nitrogen.

Foliar applications also support photosynthesis and stimulate sugar production, which feeds soil biology through root exudates. Unlike heavy soil applications, foliar feeding does not disrupt the rhizophagy cycle and can actually enhance microbial activity.

Products like KeyFactor Triple 20 can support this process by combining nitrogen with trace minerals, amino acids, and organic acids.

Foliar Feeding and Regenerative Agriculture

One of the most important shifts in regenerative systems is moving nutrient applications from the soil to the plant when possible. Foliar feeding allows growers to deliver nutrients directly where they are needed while minimizing negative impacts on soil biology.

This approach not only improves nutrient efficiency but also encourages stronger plant metabolism and better overall crop performance.

Applying Regenerative Ag Principles Beyond Corn

While this example focuses on nitrogen in corn, the same concepts apply to other nutrients like phosphorus and potassium, as well as to other crops.

The key principles remain the same. Apply less upfront, time applications based on crop demand, stabilize nutrients to prevent loss, and shift toward foliar feeding when appropriate. Over time, these practices help build soil biology and reduce dependency on synthetic inputs.

The Reality of Transitioning

Transitioning to a regenerative system is not always easy. Splitting applications and managing timing requires more planning and effort compared to a single upfront fertilizer application.

However, while conventional systems may seem simpler in the short term, they often come with higher long-term costs, both financially and in terms of soil health. Regenerative systems require more intention, but they reward growers with improved efficiency, resilience, and sustainability.
