Enhancing Fertiliser Use Efficiency For Transplanted Vegetables, Dennis Phillips, Aileen Reid, Gavin D'Adhemar Jan 2007

Enhancing Fertiliser Use Efficiency For Transplanted Vegetables, Dennis Phillips, Aileen Reid, Gavin D'Adhemar

Horticulture research reports

Horticulture Australia (HAL) Project No. VG04018.

Project VG 04018 ‘Enhancing fertiliser use efficiency for transplanted vegetables’ showed that spraying highly concentrated solutions containing nitrogen over newly transplanted vegetable seedlings for between 14 and 21 days after planting can increase marketable yields by as much as 300% compared to other methods of fertiliser application. Crops that this method has been successfully tested on in this study by the W.A. Department of Agriculture and Food include iceberg and Cos lettuce, broccoli, cauliflower, Chinese cabbage (wombok), celery and cabbage.

The research was conducted on virgin sandy soils of the Swan Coastal Plain near …

Understanding Fertilisers For Table Grapes, B. H. Goldspink, I. Cameron, J. Campbell-Clause, N. Lantzke, C. Gordon

Viticulture research reports

A course run by the Department of Agriculture, Western Australia, August 1995.

The purpose of this publication is to clarify the role fertilisers play in commercial table grape production and to detail methods of selecting fertilisers. This selection process however is not easy as there are over 600 registered fertilisers in Western Australia.

In deciding which is the best fertiliser for a particular property many factors have to be considered. These include:

* Age of vine

* Rootstock

* Variety of table grape

* Soil type

* Soil chemistry

* Irrigation methods

* Previous fertiliser history Previous yield, vigour and …
