Later on, this conference was recognized as the 1st Conference of the International Soil Tillage Research Organization (ISTRO).The review deals with tillage problems as presented by the diverse terrain and climate of the British Isles, field trials with ploughing and shallow cultivation in the Federal Republic of Germany, soil cultivation and soil conservation in the U.S.A., and some aspects of different systems of ploughing in Sweden. In the discussion following the lectures, the advantages of the then newly introduced one-way plough are stressed.
