Systems For Early Sowing Of Wheat In Low Rainfall Zones., Nicole Kerr, Glenn Adam

Experimental Summaries - Plant Research

Aims:

(i) use available climatic data to determine when breaks are likely to occur, and assess the risk of crop failure from 'false breaks'.

(ii) determine optimum methods of early crop establishment on a number of soil types, particularly massive earth soils.

(iii) determine the yield advantages of early planting of cereals, and sowing date * variety interactions. (iv) increase adoption of early sowing technology throughout the north-eastern wheatbelt.

Trial 90GE7, 90GE8, 90NM1 and 90GE10

Time of sowing * variety trials.

Location: Balla, North Mullewa and Morawa.

All of the trials the following design: 3 sowing dates (mid May, late …

Response By Stylosanthes Hamata And S. Scabra To Phosphate On Three Soils In The North-Kimberley Of Western Australia, A Mcr Holm, Mario F. D'Antuono

Resource management technical reports

Legume herbage mass was maximized after two or three years application of 50 kg/ha double superphosphate for both Verano and Fitzroy on Red earth soils and for Fitzroy on Yellow lateritic soils. There was increased production of Verano up to the maximum fertilizer level. Both varieties responded in the second year to residual P following application in the first year but there were no responses in subsequent years.

An Economic Model For Evaluating Strategies On The South Coast Of W.A. Which Reduce Wind Erosion : Documentation, A D. Bathgate

Resource management technical reports

The sandplain region on the south coast has predominately sandy soils which are subject to erosive winds when ground cover is likely to be scarce. This can often result in production losses of crop and pasture. There is concern that wind erosion will lead to the depletion of the soil resource in the long term. The model is multi-period linear programming with a planning horizon of 10 years. Effects of wind erosion on production can be imposed on the model for the first five years after the erosion event.

Busselton - Margaret River - Augusta Land Capability Study : Methodology And Results, Peter J. Tille, Neil Clifton Lantzke

Resource management technical reports

A land unit map of the region has been prepared at a scale of 1:50,000. Additional maps of climate, surface and groundwater supplies and existing land use have also been prepared at smaller scales. The capability of each of the land units to support grazing, market gardens, vineyards, orchards and forestry has been assessed. The limitations for housing on small rural lots have also been evaluated. Describes the methods by which the survey was undertakenand will be primary of use to the technical user.
