Abstract
“AGRICULTURISTS may feel that an addition to the numerous books dealing with fertilizers requires some vindication”, says the author in his preface. We agree. The author proceeds to disarm criticism by limiting the primary scope of his book to farmers, fertiliser sellers and agricultural students. The reviewer would place fertiliser sellers first in this grouping, for the needs of the farmer and student are met elsewhere. “The Use of Fertilizers” is not, however, to be dismissed as superfluous. The mixing of fertilisers on the farm, the importance of ‘condition’ in fertiliser mixtures, and the use of ‘concentrated’ mixtures, are subjects dealt with authoritatively and helpfully. It is pleasant to see repeated emphasis laid on the absence of justification for trivial differences in the composition of mixtures. Valuation and the economics of fertiliser application are, as might be expected from the author's connexion with the fertiliser trade, exhaustively handled.
