Two Decades of Surveys of Fertilizer Practice

Abstract

From their personal experience the writers of this illuminating and cathartic record have briefly covered a period of unexampled change in British agriculture. The story is passing into history. It is well to be reminded how exiguous was the use of mineral fertilizer before the second world war; how use has increased and spread; and how imperative still, in the interest of agronomic efficiency, is the continued need for scientific guidance.
