Unfortunately, it's not true. Marl contains 50% of Calcium Oxide which means the maximum dosage is 20 kg of Marl (the equivalent to 10 kg of pure CaO).

Thank you for participating though, I'm happy to have you here. Hopefully, you will stay in our community for longer - you are very welcomed here.
