Tullberg, J.N., 1994: Controlled traffic in rainfed grain production. The results of research on controlled traffic permanent bed farming systems in rainfed grain production are presented. Controlled traffic was found to reduce drawbar energy requirements by an average of 42% at tillage depths >150 mm. Smaller en...

Taylor J.H., 1983: Benefits of permanent traffic lanes in a controlled traffic crop production system. Controlled traffic research was initiated to increase crop yields by reducing traffic-induced soil compaction in the crop zone. Crop yields were increased and most of the field research was concerned with the effects of the controlled traffic syst...

Schmidt, C.J.J.; Smalberger, S.A.; Adriaanse, F.G.; Du-Preez, C.C., 2006: Relationship between inorganic soil nitrogen and maize grain yield with controlled traffic practices. Traditional N fertilizer guidelines were based on relationships between N application rates and yield response. These relationships varied greatly according to residual inorganic N content in the soil. The objective of this study was to establish...

Mcphee, J.; Braunack, M.; Garside, A.; Reid, D.; Hilton, D., 1995: Controlled traffic for irrigated double cropping in a semi-arid tropical environment. 3. Timeliness and trafficability. Journal of agricultural engineering research 60(3): 191-199

McPhee, J.E.; Braunack, M.V.; Garside, A.L.; Reid, D.J.; Hilton, D.J., 1995: Controlled traffic for irrigated double cropping in a semi-arid tropical environment: Part 3, timeliness and trafficability. Timeliness and trafficability were investigated in a research programme undertaken to assess the potential of controlled traffic for irrigated double cropping in a semi-arid tropical environment. Two controlled traffic treatments, using direct dri...

Mcphee, J.; Braunack, M.; Garside, A.; Reid, D.; Hilton, D., 1995: Controlled traffic for irrigated double cropping in a semi-arid tropical environment. 2. Tillage operations and energy use. Journal of agricultural engineering research 60(3): 183-189

Wright, G.C., 1985: Furrow irrigation of grain sorghum in a tropical environment. I. Influence of period of inundation and nitrogen fertilizer on dry matter production, grain yield and soil aeration. Total DM production by sorghum cv. Texas 610SR sown in 1982 in a 6-year-old Digitaria decumbens pasture on Cununurra clay decreased as period of inundation during furrow irrigation increased. Increasing the period of inundation from 0 to 24 h at e...

McPhee, J.E.; Braunack, M.V.; Garside, A.L.; Reid, D.J.; Hilton, D.J., 1995: Controlled traffic for irrigated double cropping in a semi-arid tropical environment: Part 1, machinery requirements and modifications. Research was undertaken to assess the potential of using controlled traffic for irrigated double cropping in a semi-arid tropical environment. The research was carried out on a cracking clay soil, in a region where the climate and availability of...

McPhee, J.E.; Braunack, M.V.; Garside, A.L.; Reid, D.J.; Hilton, D.J., 1995: Controlled traffic for irrigated double cropping in a semi-arid tropical environment: Part 2, tillage operations and energy use. Energy use was one factor investigated in a research programme undertaken to assess the potential of controlled traffic for irrigated double cropping in a semi-arid tropical environment. A controlled traffic system was used with 2 different cultur...
