Forskning og forsøk i landbruket : kulturvekstenes svovelforsyning

Abstract

This paper, by way of introduction, presents a very brief review of the known, pronounced and large sulphur-deficient areas of the world. The major factors determining the sulphur supply of cultivated plants are discussed briefly on the basis of literature studies. The importance of the atmosphere as a source of sulphur has been given more attention than the other factors. Results of experiments and other investigations in this field, as well as the opinions held on the sulphur fertilizer question in the Nordic countries, are also treated somewhat more in detail. The list of references comprises a very limited selection from the comprehensive literature on the subject in question.
