Item Water and solutes in soil : hydraulic characterisation, sustainable production, and environmental protection : application for the degree of Doctor of Science from Massey University, Palmerston North, New Zealand(Massey University, 2002) Clothier, Brent EThe soil of the rootzone, the fragile and fertile interface between the atmosphere and the subterranean realm, is characterised by massive transfers of water and solutes. Our understanding of the biophysical transport processes into, and through, soil has been enhanced by the research endeavours of the applicant, Brent Euan Clothier. Dr Clothier, a 1977 Ph.D. graduate of Massey University, has developed tools and techniques that increased the acuity of our vision of transport processes of water and solutes in soil, as well it has sharpened our ability to hydraulically characterise those mechanisms for the purpose of modelling and risk assessment. His research has also enhanced our understanding of how these biophysical processes affect sustainable agriculture, environmental protection, and the bioremediation of contamination. These endeavours are grouped, in this thesis, into four overlapping areas of research: • Processes and properties of water movement into and through soil • Processes and properties of solute movement through soil • Root uptake processes and sustainable irrigation • Plants, groundwater protection and bioremediation of contaminated soil. The key elements of these four themes, and their contribution to knowledge, form Chapters 2-5 of this thesis. Dr Clothier's awards, honours, and impact are discussed in Chapter 6.Item The role of the roots of some grass and clover species in the improvement of the soil structure of a Tokomaru silt loam : a thesis presented at Massey Agricultural College in part fulfilment of the requirements for the degree of Master of Agricultural Science, University of New Zealand(Massey University, 1955) Robinson, George StewartIt has been long been realised that grassland has a beneficial effect on the fertility of soil. This is not only the case with the natural grasslands of the world which are found in areas of limited precipitation and cold winters, and which have provided a rich harvest of grain products for many years after their initial ploughing. It is also so in those other agricultural areas where forest was the natural cover, and where it has now been found necessary to alternate the exhaustive periods of crop growing with restorative periods in pastures.
