Sustainable nitrogen provider launches soluble powders

Sustainable nitrogen provider Kula Bio has introduced two new shelf-stable, soluble powders that deliver nitrogen-fixing bacteria directly to a crop’s root zone.

Kula-NSP and Kula-NextSP build on the agronomic performance of its liquid formulations introduced in 2024, according to a news release. The powder is engineered to simplify operations, eliminate cold storage requirements and extend shelf life, according to the release.

With OMRI certification, Kula-NSP is approved for certified organic production, while Kula-NextSP is designed for conventional agriculture. The company plans to pursue biostimulant certification from The Fertilizer Institute (TFI).

Kula-N, Kula Bio’s flagship solution, has been approved as a certified biostimulant by TFI.

“This launch reflects our commitment to delivering practical, reliable solutions that are easy for farmers and distributors to adopt at scale,” Kula Bio CEO Harrison Yoon said. “Our focus was on combining consistent biological performance with a product that can be stored, handled, and applied seamlessly in commercial agricultural settings without compromising quality.”

How it works

Both products feature Xanthobacter autotrophicus, a nitrogen-fixing microbe able to store its own energy. Kula Bio’s proprietary manufacturing process enhances these microbes, providing them with a robust internal carbon reserve that boosts their natural nitrogen‐fixing capabilities.

In comparative studies, Xanthobacter autotrophicus demonstrated up to 65% greater efficiency in nitrogen fixation compared to conventional nitrogen-fixing bacteria, according to the company.

Once applied to the soil, the organism actively converts atmospheric nitrogen into plant available forms directly in the root zone for a steady, targeted uptake of nitrogen.

“Growers are under pressure to produce more with fewer inputs, tighter regulations, and unpredictable markets. Kula-NextSP and Kula-NSP give them a reliable biological alternative that performs in real‐world conditions with cost competitiveness to fit their nitrogen programs,” said Geraldo Mattioli, Kula Bio chief commercial officer.
