ARBOK solution

How the ARBOK system creates value

CRONA is a system that replaces fertilizers as a product.

It does not produce them in factories, does not transport them, and does not apply them to the field.

It does something different — it creates plant nutrition directly inside the soil during field operation.

In the conventional model, a farmer buys fertilizers made from gas, shipped across the world, and spread over the field. With CRONA, this entire chain simply does not exist.

Instead, the system uses soil, water, and air — and in a single tractor pass converts bound elements into an active form, the same form that plants can absorb.

Nitrogen, phosphorus, potassium are already in the soil — but they are locked.

CRONA unlocks them.

Nitrogen is in the air — CRONA binds it.

Water is no longer just water — it becomes a carrier of nutrients.

And this does not happen over a season.

It happens instantly.

At the moment the tractor passes, processes that normally take years are triggered in microseconds.

As a result, CRONA does not improve fertilization. It removes the need for it.

CRONA operates during a standard soil preparation pass using a tractor-mounted system.

The soil is first mechanically loosened to create a uniform and conductive structure. Water is then introduced into the loosened layer, forming a conductive medium. A short, high-energy impulse is delivered into the wetted soil through a contact system.

This creates an electrical discharge within the soil, similar to a localized lightning strike. As a result:

  • Bound soil compounds break down
  • Nitrogen, phosphorus, potassium, and microelements become available
  • Nitrogen oxides (NO₂, NO₃) are formed in situ

Processes that normally take years occur almost instantly.

Additionally, atmospheric nitrogen is fixed during operation, introducing new nutrients without external inputs.

The process also modifies soil structure and activates biological processes, resulting in long-term fertility improvement.

Market and application

Commercial opportunity

The global fertilizer market exceeds $200+ billion annually, with nitrogen fertilizers representing the largest segment.

CRONA targets:

Operating Principle

CRONA operates during a standard soil preparation pass using a tractor-mounted system.

The soil is first mechanically loosened to create a uniform and conductive structure. Water is then introduced into the loosened layer, forming a conductive medium. A short, high-energy impulse is delivered into the wetted soil through a contact system.

This creates an electrical discharge within the soil, similar to a localized lightning strike. As a result:

  • Bound soil compounds break down

  • Nitrogen oxides (NO₂, NO₃) are formed in situ

Processes that normally take years occur almost instantly.

Additionally, atmospheric nitrogen is fixed during operation, introducing new nutrients without external inputs.

The process also modifies soil structure and activates biological processes, resulting in long-term fertility improvement.

Architecture and Components

The system consists of a tractor-mounted modular unit:
