Sydney start-up Regrow Ag is the first to leverage Google Earth Engine

“Satellites regularly orbit the Earth and constantly collect images of every square inch of the Earth,” said John Shriver, data scientist at Regrow.

“We use this time series of data to be able to monitor what is happening on a field over time.”

Data collected by Regrow includes short-wave infrared imagery that can reveal plant health, the proportion of green cover to soil in a field, and the amount of “crop residue” left after harvest. The information collected can be used by producers to adjust their inputs or crop type to increase yield, and calculate the carbon they emit or sequester through their farming practices.

Shriver said farmers often reduced their tillage practices or resumed planting a cover crop, rather than leaving fields bare, in response to data from Regrow.

“The less you plow the field, the less carbon you release into the atmosphere. And if you plant a cover crop, which could be clover, ryegrass, any type of plant that’s going to grow through the winter, it clings to the ground in the field and minimizes emissions during this winter season where bare ground is going to have,” Shriver said.

“What we can do is give the farmer some certainty as to what they are going to be paid to adopt these practices and participate in the carbon market.”

In May, as Volkova managed her mother’s evacuation from Ukraine, Regrow raised $50 million led by US investors including Tom Steyer and Katie Hall’s Galvanize Climate Solutions and Salesforce founder Marc Benioff’s TIME Ventures. . Last year, the startup raised $24 million in Series A funding.

Access to decades of agricultural field data will help growers adapt to an environment made unstable by destructive floods and increased drought caused by climate change, Shriver said.

“In extreme rain or extreme heat where there’s a lot of drought, we can recommend different agronomic practices to help them maintain high yields even in the face of some of these new climatic stresses.”
