Most organic matter left at the soil surface decays and is returned to the atmosphere as CO2. Our approach seeks to maximize the transfer and preservation of organic matter in soil. Our process injects organic matter to a depth of 2 feet, where it is composted and converted to stable organic carbon.

Progress from February to April 2024

This is a series of images from our Norman test site. Pellets were injected in August of 2023. The image series follows the growth of vegetation from February through the first week of April 2024. The blocks with alfalfa pellet injection green up with growth well before the surrounding field. 

By March the squares with injection are well ahead of the surrounding control squares.

By the first week of April the vegetation is lush and showing no signs of slowing down. 

Our new Carbon Injection Platform is mounted into the back of a Japanese mini-truck. The platform is in its final stages of construction and early stages of testing. We anticipate using this platform to service our first customers in late spring and early summer.

Castlerock park soil restoration

Here at Castle Rock Park in Norman we have begun a soil restoration site in an area that has poor soil and won't grow any grass or vegetation. This manual method is perfect for areas our mini-truck can't fit, like flower beds or raised garden beds. 

At this site the soil has high salinity and poor drainage. The recommended remedy is to increase organic matter and increase drainage. This is exactly what our method provides. The 2ft deep columns of alfalfa pellets provide a pathway for dissolved salts to pass out of the topsoil. The pellets as they break down provide organic matter and nutrients for plants and soil organisms.
