Effects of design and kinematic parameters of rotary cultivators on soil structure



Effects of design and kinematic parameters of rotary cultivators on soil structure



Tillage and traffic in crop production Proceedings of the 11th international conference of the International Soil and Tillage Research Organization, Edinburgh, UK, 11-15 July, 1988: 463-468



A quantitative basis for description of soil structure created by rotary cultivators is given. Undisturbed Ap horizon samples were collected, impregnated with polyester resin, sectioned by sawing and analysed by means of a Quantimet 720 image analysing computer. Total porosity, area and size of pores were related to design and kinematic parameters of the rotary cultivator, arising from an analysis based upon the location of instant centres of velocity.
