Earning the Right For Nutrient Use Efficiency: Why Soil Health and Fertility Come First

During a recent webinar hosted by Soil Carbon Innovations (SCI), renowned agronomist Gary Zimmer shared a message that resonated deeply with growers across the country:

Every farmer wants to be more efficient — but efficiency has to be earned.

Whether it’s nitrogen, crop protection products, or cattle feed, the goal is the same on almost every farm:

• Use less while getting more

• Improve margins without sacrificing yield or performance

• Reduce risk while building long‑term resilience

But as Gary emphasized, these outcomes don’t come from simply cutting inputs. They come from building soils that can do more of the work themselves.

What Farmers Want — and Why It Makes Sense

Gary laid out four goals nearly every producer shares:

1. Greater Nitrogen Efficiency

Nitrogen is expensive, volatile, and increasingly scrutinized. Farmers want:

• More pounds of grain per pound of N applied

• Less loss to leaching, volatilization, and denitrification

• Better uptake when crops need it most

2. Reduced Dependence on Other Fertilizers

No one wants to overapply phosphorus, potassium, or micronutrients. The goal is:

• Better nutrient cycling

• Higher bioavailability

• Lower long‑term input costs

3. Lower Plant Protection Costs

Herbicides, fungicides, and insecticides are significant line items. Farmers want:

• Crops that are naturally more resilient

• Fewer disease and insect issues

• Less reliance on reactive chemistry

4. More Nutrient‑Dense Feed for Livestock

For cattle producers, feed efficiency is profitability. The desire is:

• More nutrition per pound of feed

• Healthier animals with fewer supplements

• Lower feed costs over time

These goals are not unrealistic. But they cannot be achieved by shortcuts.

The Key Insight: Efficiency Must Be Earned

Gary Zimmer described this process as “earning the right.”

The right to:

• Apply less nitrogen

• Reduce fertilizer rates

• Spend less on crop protection

• Rely on higher‑quality forage and feed

That right is earned by building soil health and soil fertility.

Soil Health and Soil Fertility

One of Gary’s most important teachings is that soil health and soil fertility must work in balance.

• Soil fertility is the maximum level of nutrients exchangeable in the soil for optimum crop performance.

• Soil health is the capacity of the soil to function without intervention by having proper structure, permeability, and biology.

Without biology, structure, and carbon:

• Nutrients move freely out of the system

• Roots struggle

• Inputs become increasingly inefficient

When soils function as nature designed:

• Nutrients stay in the root zone

• Biology mediates availability

• Crops self‑regulate stress more effectively

The Timeline: 3–5 Years of Intentional Focus

Building soil health is not a one‑season fix.

Most farms require 3 to 5 years of consistent, intentional management focused on:

• Feeding soil biology

• Increasing biologically active carbon

• Supporting mineral balance

• Improving aggregation, infiltration, and root growth

  
  

During this period, farmers may not immediately reduce inputs — and that’s okay.

The goal early on is not reduction. The goal is capacity building.

As soils improve, efficiency follows.

If typical row crop roots have direct contact with only 1% of the soil in which they reside, building soils that allow for increased root systems that allow a plant to make contact with 2% of the soil, will allow a plant to achieve the same yield result with dramatically lower water and fertilizer inputs.

• You can’t buy improved root‑soil contact

• You build it by:

  • Aggregation

  • Biology

  • Carbon

  • Time

Soils that function biologically:

• Maintain continuous water films

• Reduce diffusion bottlenecks

• Allow roots to “see” far more soil without growing far more roots

The most significant Input reductions come after capacity is built

The Long Game Pays

Farmers who stay the course often find that:

• Nitrogen rates decline without yield loss

• Crops show better stress tolerance

• Disease and insect pressure decreases

• Feed quality improves

• Profitability becomes more stable year after year

That’s not luck. That’s biology doing its job.

Where Living Carbon Fits In

At Soil Carbon Innovations, this philosophy shapes everything we do.

Products like Living Carbon and Biochar are not about:

• Replacing fertilizer

• Cutting rates overnight

• Promising instant savings

They are about building the biological and carbon foundation that allows farmers to eventually:

• Get more value from every pound of nutrients

• Reduce losses

• Improve crop and livestock performance naturally

In other words, Living Carbon and Biochar help farms "Earn The Right." Contact us to learn more about how SCI can help you earn the right.
