Abstract
I began this PhD study at the Department of Soil Science and Plant Nutrition at Wageningen Agricultural University (WAU), The Netherlands in October 1993. The aim of the study was to increase the understanding of nitrogen losses in maize cropping on Vertisols, and to develop soil and crop management options to reduce such losses and improve crop growth and nutrient uptake. The study involved both laboratory and field investigations, and was partly conducted in The Netherlands, and partly in Kenya. Inevitably, the study called for the participation of many individuals without whose help - financial, technical, logistical and moral - I would not have completed it.
