New soil has arrived for a re-run of our XXL lysimeter experiment. After 3 years of measurements we will dismantle 15 of the 20 large lysimeters and fill them with new soil and rock dust. 5 pots will continue for year 4 and 5.

Today, 4 years ago, we started our first enhanced weathering field trial in Fürth. Back then we had no idea that this soil would turn out to be basically useless for CDR, it is a “cation eating monster soil”. The lack of CDR signal triggered world’s largest greenhouse experiment

This week at Carbon Drawdown Initiative we prepared 22 soils for our new greenhouse experiment for enhanced weathering. These soils are from all over Germany and from various european countries. About 15 more soils from all over the world are expected to arrive over the summer and will

Today more than 20 volunteers (most of them from Analytik Institut Rietzler GmbH) helped us to re-load our XXL lysimeter experiment for enhanced weathering in Fürth/Germany. We needed to remove 6 tons of soil from 15 large buckets - litterally by hand - while taking extensive

This is our scientific treasure Carbon Drawdown Initiative: more than 2,000 soil samples taken from our enhanced weathering experiments (greenhouse and outdoors) since early 2022. Thousands of hours of (wo)men-power, hundred thousands of Euros, the support of the EW science and the EW

Nach der Dekarbonisierung brauchen wir pro Jahr 4-9 Gt CO2 negative Emissionen (IPCC). „Der Aufbau dieser neuen Industrie wird eine immense Herausforderung sein“ Wir müssen also JETZT anfangen. Carbon Drawdown Initiative forscht seit 2019 an der Verstärkung der natürlichen Verwitterung ⬇️

After only 3-4 weeks effects of rock dust amendments on plant growth are already visible! Four weeks after setup, of which the first two weeks were without any rain, we finally see germination of weeds on our XXL lysimeters which all use the same German soil. It becomes visible

Update one week later: 5 weeks after setup the germination of the weed seeds (we think it is White goosefoot/Chenopodium album) brought along by the new soils of our XXL lysimeter experiment has progressed further. The 6 controls and 6 Greenland Glacier Dust treated pots are
