Fate Of Nitrogen From The Disposal Of Poultry Litter: A Simulation Approach, B. A. Ibrahim, H D. Scott
Fate Of Nitrogen From The Disposal Of Poultry Litter: A Simulation Approach, B. A. Ibrahim, H D. Scott
Technical Reports
A computer program was written to simulate the transport of nitrogen after an application of poultry litter to a pasture. The program was written in FORTRAN 77 to run on an IBM PC/AT or compatible personal computer or on a Sun SPARCSTATION. Simulation of water, solute and heat transport was by finite difference. Partition of rainfall into infiltration and runoff was by the SCS curve number method. A comparison was made of the computer model output with the results of a field experiment established at the Main Agricultural Experiment Station at Fayetteville. Poultry litter was applied at a rate of …

Salinity And Waterlogging On The Esperance Downs Research Station, D J. Mcfarlane, A T. Ryder
Salinity And Waterlogging On The Esperance Downs Research Station, D J. Mcfarlane, A T. Ryder
Resource management technical reports
Details the situation on the station so that the demonstration and research programs can be designed and the effect of the treatments assessed. Past work on the station has been briefly summarised and the results of geophysical surveys and additional drilling are given. Surveys of electromagnetic terrain conductivities have shown where salinity is most serious at present. The most deeply penetrating method may have identified areas likely to developing salinity in future.

Preliminary Groundwater And Salinity Investigation In The Eastern Wheatbelt. 4. Kitto's Hillslope, Tammin - 1985-90, Richard J. George Dr
Resource management technical reports
The investigation revealed that a deep, brackish to saline groundwater system and dolerite dyke, contained within the saprolite were responsible for the secondary salinity; the annual discharge of water and salt at the seep from the damp groundwater system was about 2800 kL and 17 tonnes respectively; and the water-tables were not rising and that the most appropriate management of the site was to plant salt tolerant forage plants in combination with trees.

Preliminary Groundwater And Salinity Investigation In The Eastern Wheatbelt. 1. Brennand's Catchment, Richard J. George Dr, P W C Frantom
Resource management technical reports
Groundwaters were found to be 10 m below the floor of the ancestral playa lake in Brennand's catchment. They were extremely saline. A groundwater flow system was not established on much of the catchment. Flow was observed to be occurring from recharge areas near the playa lakes towards the midslopes of the catchment. Flow was apparently restricted from leaving Brennand's catchment because of obstruction to groundwaters created by dolerite dykes.
