Are you skeptical of marketing claims for new agricultural technologies that replace traditional fertilizer?

Independent testing at Washington State University revealed that Green Lightning's equipment produces significantly less nitrogen than marketed. In 2024, field trials confirmed that crops using the product yielded fewer bushels per acre than conventional fertilizer.

Why it matters

Discrepancies between advertised performance and actual output can lead to significant economic losses for farmers relying on equipment efficiency. These findings highlight the necessity of verified technical assessments for agricultural technology.

A Green Lightning machine produces 161 pounds of nitrogen annually compared to a company claim of 109,500 pounds. Field trials showed corn yields of 235.9 bushels per acre with the equipment versus 280.7 bushels using conventional fertilizer.

The players

Washington State University Extension

This organization conducts independent agricultural research and provides extension services to farmers across Washington state.

Precision Planting

This company specializes in agricultural technology and conducted the field trials assessing corn yield performance.

Green Lightning

This company manufactures agricultural equipment that claims to replace conventional nitrogen using plasma chemistry.

The details

The equipment utilizes electrical plasma chemistry to oxidize nitrogen from the air into nitrate in water, but testing indicated the actual output is limited to 161 pounds annually at a rate of 100 gallons per day. During 2024 trials, 120 gallons of the product were applied per acre to test plots.

Washington State University testing and Precision Planting field trials occurred throughout 2024.

Culture Shift

The agricultural sector is currently undergoing a broader push toward sustainable, independent nitrogen production through new electrical technologies. This trend forces a reevaluation of performance claims as farmers seek alternatives to traditional, industrial fertilizers.

Farmers in Washington state should carefully evaluate the performance specifications of new nitrogen-fixing equipment before integrating it into existing operations. Relying on unverified claims may result in lower crop yields and reduced profitability compared to established conventional methods.

The takeaway

Farmers should prioritize equipment backed by verified, independent field performance data to protect their seasonal yields. Relying solely on marketing specifications without rigorous testing risks significant financial disruption to agricultural output.
