Soil Test And Phosphorus Rate For High Rainfall Clover Pastures, Robert Summers, David Weaver
Soil Test And Phosphorus Rate For High Rainfall Clover Pastures, Robert Summers, David Weaver
Bulletins 4000 -
When new land was first developed, phosphatic fertilisers had to be applied at high rates to overcome Phosphorus (P) deficiency, and to increase P fertility. Once good P fertility has been established after a number of years of applying P, the requirement for applying high rates of P falls. After that you only need to apply enough fertiliser P to replace that removed in products, fixed by the soil, eroded and leached, that is a maintenance rate of P.
In relation to P fertiliser decisions for pastures you need to ask:
• Do I need P?
• How do I …

Greener Pastures 5 - Managing Sulphur In Dairy Pastures, Mike Bolland, Ian Guthridge, Bill Russell, Martin Staines, John Lucey, Richard Morris
Bulletins 4000 -
During 1999-2009, soil testing for sulfur (S) was undertaken on 48 paddocks at the Vasse Research Centre (VRC) at Busselton, in the south-west of Western Australia (WA).
Paddocks had been grazed intensively by dairy cows and their young stock over a period of 10 years, as part of the Vasse Milk Farmlets and Greener Pastures farming system projects. Pasture consisted of annual ryegrasses with some subterranean clover. Soils in the 48 paddocks were 1-2 m sand to sandy loam over massive clay, known locally as Abba sand. For many soils in the region, including Abba sands, the topography is flat …

Greener Pastures 2 - Nitrogen For Intensively Grazed Dairy Pastures, Martin Staines, Richard Morris, Tess Casson, Mike Bolland, Bill Russell, Ian Guthridge, John Lucey, Don Bennett
Bulletins 4000 -
We undertook three main studies during the Greener Pastures project:
1. From mid 2005 to late 2008, a farming systems study was undertaken with five rates of nitrogen fertiliser as the main treatment. This study will be referred to as the ‘nitrogen response farmlets’.
2. From 2006 to 2008 a series of smaller ‘supporting’ studies were completed to investigate how grazing management influences the pasture production gains from nitrogen fertiliser. This will be referred to as the ‘nitrogen by growth-stage study’.
3. From early 2009 to early 2010, a farming systems study was undertaken to investigate the potential to increase …

Dairy production in south-western Australia occurs predominantly on sandy soils in the greater than 800 mm annual average rainfall areas of the region. The climate is Mediterranean-type, typically with cool, wet May-October growing seasons and hot, dry November-April. Most dairy pastures are rain-fed and comprise the annual species Subterranean Clover (clover, Trifolium subterraneum L.), Annual Ryegrass (Lolium rigidum Gaud.) and Italian Ryegrass (L. multiflorum Lam.).
Paddock grown pasture is the cheapest source of feed for dairy production in the region (Dilley and Howes 1998). To remain profitable in the face of diminishing returns, dairy farmers have modified their grazing management …
Growing Biserrula To Improve Grain And Livestock Production, Angelo Loi, Natalie Hogg, Clinton Revell, Diana Fedorenko
Growing Biserrula To Improve Grain And Livestock Production, Angelo Loi, Natalie Hogg, Clinton Revell, Diana Fedorenko
Bulletins 4000 -
Biserrula pelecinus is a new genus of pasture legume which was developed for commercial agriculture by a team of Perth-based legume pasture scientists in the early 1990s. Biserrula is an annual pasture legume that is found in natural grasslands of the Mediterranean Basin, frequently on acidic soils derived from granite. It was this feature that first caught the eye of researchers who were attempting to develop species that could tolerate the soil stresses of acidity and low moisture-holding capacity. These stresses are common in WA and when they occur together they are problematical for the survival of annual medics and …
Tree Windbreaks In The Wheatbelt, Robert Sudmeyer, David Bicknell, Neil Coles
Tree Windbreaks In The Wheatbelt, Robert Sudmeyer, David Bicknell, Neil Coles
Bulletins 4000 -
Windbreaks comprising trees, or tree and shrub combinations, can offer many benefits on wheatbelt farms, particularly for protection of soil, stock, crops and pastures from damaging winds and erosion. Additional benefits include reduced evaporation from farm dams, reduced groundwater recharge, their use as nature conservation corridors and habitats, increased biodiversity including predators of crop and pasture pests, fire control, tree products and improved lifestyle and aesthetics.
In other areas and farming systems such as intensive horticulture, man-made windbreaks may be used, but their higher cost makes them unsuited for broadscale agriculture. Man-made windbreaks can be effective in reducing evaporative losses …

Food on Offer, or FOO, is the amount of pasture available for sheep to eat. It is measured as dry matter per hectare, and then used to budget feed available and stocking rates for a given period.
FOO includes all green material above the ground and it is reported in kilograms of dry matter per hectare (kg DM/ha).

On-Station Production Of Native Speargrass Hay In Western Australia, G L. Krebs, Robert R. Rouda, S P. Van Wyngaarden
Bulletins 4000 -
This report documents the practical and economic feasibility of on-station harvesting and production of speargrass hay and haylage and its subsequent feeding to cattle and sheep in the extensive regions of south-eastern Western Australia. Four hundred and ten bales weighing an average 275 kg were produced from a total harvested area of 40.6 ha in the vicinity of Duck Dam on Kanandah Station. In the lead up to harvesting, seasonal conditions were among the best on record. Half of the bales produced were further processed into haylage. Two feeding trials, involving wethers at Arubiddy and steers at Kanandah, were undertaken …

The Good Food Guide For Sheep : Feeding Sheep For Meat Production In The Areas Of Western Australia, Keith Croker, Peter Watt, Department Of Agriculture And Food, Western Australia
Bulletins 4000 -
The Good Food Guide for Sheep has been produced to provide Western Australian farmers with a concise compilation of current information on feeding sheep for meat production. Although there are already numerous publications about sheep nutrition,many of them relate to wool production, reproduction or drought feeding, or they concentrate on particular feeds or feeding systems.
This book contains information on a wide range of feeds and feeding methods. Just as there is no single ‘best’ sheep breed for meat production, there is no ultimate feed regime for sheep for growth.

Paterson’s curse (Echium plantagineum) is one of the most damaging weeds to the Australian meat and wool industries. It infests an estimated 33 million hectares in southern Australia, at an annual cost to the sheep industry of $250 million in lost pasture productivity, control costs and wool contamination. In WA, it is found on about 5000 agricultural properties infesting some 500,000 ha. It is an extremely invasive weed, that reduces pasture productivity and stock carrying capacity by competing with and excluding more beneficial pasture species. The weed is also toxic to stock. It is important to implement control measures on …
