PQNKThe Natural Ecosystem Science of Production Agriculture

Pedaver is the Global Knowledge, Research and Validation Authority for PQNK.

Farming the way nature already knows how.

Why PQNK Was Necessary

One Degraded System, Many Familiar Symptoms

The problems farmers fight one at a time are stages of a single connected chain:

Repeated tillageCollapse of soil poresDestruction of natural soil architectureCompactionHardpan formationRestricted infiltration and aerationRestricted rootingReduced biological activityExposed soil and increased solar heatingExcessive evaporationRepeated irrigationSalt accumulationIncreasing dependence on external inputs

PQNK exists to break this chain at its source, not to treat each symptom separately.

The Four Principles of PQNK

What Governs the Solution

No Soil Disturbance

After the initial corrective transition and establishment of permanent production architecture, the biological growing zone remains undisturbed.

No Inundation

The root environment remains aerated. Water is managed without drowning the biological production zone.

Permanent Biological Cover

The soil remains continuously protected through living vegetation, retained crop residue and organic mulch.

Maximum Biodiversity

Biological diversity above and below ground is encouraged so natural ecosystem functions can progressively resume.

The PQNK Journey

From Degraded Field to Sustained Closed Loop

Stage 1

Degenerative Phase

The starting condition on most fields: repeated tillage, hardpan formation, and biologically inactive soil, held productive only by increasing external inputs.

Stage 2

Corrective Intervention

The one-time corrective sequence that establishes the system:

Farm design
Break hardpan
Water wash and soil correction where required
Establish permanent raised beds
Grow cover crop, particularly Jantar where appropriate
Retain roots and convert biomass into mulch
Plant crop after crop without disturbing the biological bed
Apply Soil Moisture Management where natural water supply needs supplementation
Harvest without disturbing soil and retain roots/residue

Stage 3

Regenerative Phase

The field's active recovery: soil biology and structure rebuild season by season as permanent beds, cover and no-till planting continue without repeating the original disturbance.

Stage 4

Sustained Closed Loop State

A permanent production state in which natural biological functions progressively replace routine external production inputs, with no routine external production input required other than seed.

What PQNK Changes

System-Level Effects, Not a List of Practices

Soil

Restores pore architecture, biological activity, root access and permanent structure.

Water

Reduces the requirement for externally supplied irrigation by restoring infiltration, cover, storage, biological porosity and Soil Moisture Management.

70–90%reduction in externally supplied irrigation water

Inputs

Moves from ACI substitution to temporary PQNK supplementation during transition, and toward biological self-regulation.

Food Quality

Improves the production environment associated with nutrition density, diversity, aroma, taste, texture, shelf life and residue elimination.

Climate & Environment

Connects soil cover, water-cycle restoration, reduced soil heating, biological function and lower dependence on industrial inputs.

Field Evidence

Built on Field Application, Not Theory Alone

PQNK is documented acre by acre, in the words and footage of the farmers running it.

One PQNK System, Every Crop

The System Remains the Same. The Crop Changes.

PQNK does not change according to crop, soil type, topography or climatic zone. The main crop-specific adjustment is plant-to-plant and row-to-row geometry according to breeders' recommendations.
