Mining and Manufacture of Fertilising Materials, and their Relation to Soils

Abstract

THERE is at present no good book in English on the manufacture of artificial fertilisers, but there is ample room for one. Mr. Lloyd does not quite supply the need. He evidently knows something about the mining and working of Florida phosphate rock and the making of superphosphate, but in stead of giving a clear description of all this, illustrated by diagrams, he occupies valuable space with an account of soils and soil analysis which the reader could far better obtain elsewhere. Yet there is scarcely a more vital industry at the present time than the manufacture of artificial fertilisers, nor is its importance likely to diminish.
