Popis: This paper examines the value of cultivation experiments in which crop yields are taken as a measure of the effects of different tillage treatments The soil properties important in plant growth, which can be influenced by cultivation, are discussed together with the problems of measuring these properties in the field. In particular, the importance of cultivations in water movement, the resistance of soil to root penetration and in aeration are considered. Experiments to measure the oxygen consumption of soils and plant root systems under near-field conditions are briefly described and a method outlined of measuring the rates of diffusion of gases in soil in situ. Results are given of some preliminary experiments to examine the effects of soil physical conditions on oxygen consumption.
