Maintaining healthy soil is crucial for sustainable agriculture, but the use of synthetic fertilizers can have negative impacts on the environment. NPK² is a liquid soil enhancer that provides a cost-effective and sustainable alternative to synthetic fertilizers. With the use of nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, and potassium-solubilizing bacteria, NPK² increases crop yields while reducing the need for commercial fertilizer by up to 50%.

The Power of Microbes

Microbes play a crucial role in reducing the need for commercial fertilizer by enhancing its effectiveness. Nitrogen-fixing bacteria form a symbiotic relationship with plant roots, providing a steady supply of fixed nitrogen in exchange for sugars from the plant. This helps to sustain soil fertility over time, reducing the need for regular application of commercial fertilizers. Other microbes, such as mycorrhizal fungi, improve the uptake of essential nutrients from the soil and contribute to soil fertility, reducing the need for commercial fertilizers. Phosphate solubilizing bacteria can solubilize and mobilize inorganic phosphate in soil, increasing its availability to plants. Potassium-solubilizing bacteria solubilize insoluble potassium compounds in the soil into plant-available forms, leading to improved plant growth and yield.

NPK² Symbiotic Consortium

NPK²'s powerful trio of nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, and potassium-solubilizing bacteria is composed of several different strains. Enzymes used in plant growth include nitrogenase, nitrite reductase, catalase, amidase, cellulase, glucosidase, phosphatase, protease, sulphatase, urease, and dehydrogenase.

This innovative microbial solution is optimized through synthetic biology tools to enable biological nitrogen fixation (BNF) for corn in fertilized fields. The safe commercialization of root-associated diazotrophs, such as Klebsiella variicola 137-1036, which increases nitrogen fixation activity 122-fold in nitrogen-rich environments has been proven. NPK² has been tested in multi-year, multi-site field trials throughout the U.S. Corn Belt and exhibited both higher yields and reduced within-field yield variance compared to fields fertilized with synthetic nitrogen fertilizers alone.
