A study of the effect of periodic irregularities of fertiliser distribution along the row on the establishment, growth, development and yield of barley : a thesis presented at Massey College in part fulfilment of the requirements of the degree of Master of Agricultural Science in the Victoria University of Wellington

Abstract

A considerable volume of evidence derived from field trials throughout New Zealand points to the application of artificial fertilizers (especially superphosphate) to pastures and crops as a primary factor in increased yields: The efficiency of the fertilizer is dependant on the care taken to ensure maximum recovery of the applied nutrient by the crop. This means a consideration of factors such as, time of application, quantity applied, form of fertilizer and also correct placement and efficient distribution. [From Introduction]
