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

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.
