Emerging Technologies for Making Nitrogen Fertilizer On-Farm

From smallgrains.wsu.edu

In recent years, a growing number of dryland producers have been exploring ways of producing their own nitrogen fertilizer, on-farm. For some, this means making their own biological products by brewing compost teas (opens in new tab) and making compost extracts that can be applied in a liquid form, for instance as a seed inoculant or foliar application (opens in new tab). Others are trying out a new technology sometimes called Plasma Assisted Nitrogen Fixation (PANF), which uses low-temperature plasma to fix atmospheric nitrogen into nitrate. For example, the company GreenLightning sells a system that installs on top of a liquid tote, and only requires water and 110V electricity to produce a nitrate solution (approximately 530 ppm nitrate-N, or 0.00442 lb N per gallon).
