soil water deficit

Catalogue: GRDC Final Reports
Experimental data are presented that show that fallow management, in particular that of weeds and residue cover, not only affects the amount of water stored or lost during the summer, but also has an effect on the loss of water past the root zone during the subsequent growing season... Model simulations capture these effects and a scenario analysis indicates that retaining residues past sowing increases the risk of deep water loss relatively rapidly... The effects of different residue management will be greater in wetter summers...

Using a water diviner in a maize field.. Recent efforts to improve on-farm water use efficiencies have resulted in more use of soil moisture monitoring tools, particularly capacitance probes such as C-probe, Enviroscan and Diviner... Probes are typically used to: schedule irrigations - to determine when irrigation is required calculate soil water deficit to work out how much water to apply...

An understanding of sorghum crop development and the environmental drivers of crop development is critical if we as managers are to maximise the crop performance through irrigation... A critical part of irrigation management in grain sorghum is irrigation timing, while meeting the evaporative demand is also important it can result in very poor water use efficiency (WUE) if the irrigation is applied at the wrong time... In a replicated irrigation trial conducted by Pacific Seeds at Bowenville we measured a 2% per day yield loss from moisture stress at booting under mild temperatures (Figure 4)...
