Depth Of Placement And Rates Of Nitrogen For Lupins On The South Coast., M. Seymour
Experimental Summaries - Plant Research
Trial 90E13
Starter nitrogen for lupins, rates x depth of placement.
To determine if the application of nitrogen at seeding will enable lupins to grow vigorously at the beginning of the season, and have better growth at flowering. Deep placement is used to reduce the effects of high nitrogen fertiliser on plant establishment.

Evaluation of soil test for phosphate on sandy soils.
Results presented for this project, commenced in 1988, which started as a joint project between the Department of Agriculture and Soil Science and Plant Nutrition, School of Agriculture, University of Western Australia.
In the field experiments, 10 levels of superphosphate (three replicates) were applied in May 1988, and 10 levels of superphosphate (also three replicates) were applied in May 1989 onto an adjacent area to the 1988 treatments. Colwell P I(soil test values) and yield data are presented for 1988 and 1989 for the 1988 treatments layed out in 1988, and …
