Soil Health: How to Benefit from More Diversity

By Marlon Winger
 
Brendon and Sheldon Rockey of Center, Colorado, grow and market specialty potatoes and specialty seed potatoes. They are regenerating the soil ecosystem while using fewer chemical and synthetic fertilizer inputs.
 
How do they do this in an apparent monoculture? Brendon Rockey says, “Without diversity, I wouldn’t be able to do it.”
 
They learned that they could reduce production costs while maintaining yield and increasing quality by:

Steadily increasing biological diversity through different strategies like

  • Diverse cover cropping
  • Minimizing soil disturbance
  • Integrating livestock
Implementing other soil health practices like
  • Cutting their inputs
  • Using a probiotic approach
  • Managing pests without pesticides

No-Till vs Tillage: Why Neighboring Fields Are World Apart

Video: No-Till vs Tillage: Why Neighboring Fields Are World Apart

“No-till means no yield.”

“No-till soils get too hard.”

But here’s the real story — straight from two fields, same soil, same region, totally different outcomes.

Ray Archuleta of Kiss the Ground and Common Ground Film lays it out simply:

Tillage is intrusive.

No-till can compact — but only when it’s missing living roots.

Cover crops are the difference-maker.

In one field:

No-till + covers ? dark soil, aggregates, biology, higher organic matter, fewer weeds.

In the other:

Heavy tillage + no covers ? starving soil, low diversity, more weeds, fragile structure.

The truth about compaction?

Living plants fix it.

Living roots leak carbon, build aggregates, feed microbes, and rebuild structure — something steel never can.
