Soil Carbon Sequestration and Organic Wastesomorphisms. Decisive progress was made by R. Heitmann who proved how to get rid of Noetherian hypotheses. Further progress was made by T. Coquand who proved how to obtain all the results, sometimes in a stronger form, by constructive and elementary proofs.
