Public ISBD Titre : Sulphur in Northern Nigerian soils : the effects of cultivation and fertilizers on total S and sulphate patterns in soil profiles Type de document : texte imprimé Auteurs : Bromfield, A. R. Année de publication : 1972 ISBN/ISSN/EAN : CI-05743 Note générale : This paper describes a study of the effects of management, fertilizer and farmyard manure on the form and distribution ol sulphur down the profiles of some northern nigerian soils. These soils contain little total-S/ the mean amont measured by goldsworthy & heathcote (1963) for the northern Guinea savannah zone was 42 ppm. Whitehead (1964) gives the range, for surface soils, of from 22 to 8000 ppm.
