The Site

The site was often very wet throughout winter and previously had a pasture base of annual ryegrass and clover that was highly variable in production partly due to the waterlogged nature of the paddock. Resolute tall fescue was selected as it is known to tolerate water logging and also persists well under heavy rotational grazing.

The production from the tall fescue was compared to a paddock with a typical annual pasture of sub clover and annual ryegrass with varying amounts of broadleaf weeds and grasses


Kelvin used glyphosphate and chlorpyrifos prior to sowing to control annuals and red legged earth mite.

The seed was sown at 17.5 kg/ha with a disc machine and rolled after sowing to ensure good seed to soil contact.

Tall fescue needs to be sown at a rate of at least 12 kg/ha as the seed is similar in size to ryegrass – so a higher rate is needed to get an adequate plant density. Kelvin believes it’s important to go in with a heavy rate rather than skimp on seed and risk the failure of the stand.

MCPA was used in 2007 to suppress broad leaf weeds that germinated after seeding. No fertiliser was used at sowing due to high pre-existing soil nutrient levels.

A nitrogen-based fertiliser was used in 2007 and 45 kg/ha N, 3 kg/ha P and 3 kg/ha S was applied. Research work at Hamilton in Victoria has shown that tall fescue is very responsive to nitrogen applied in early autumn.


Details of measurements taken on EverGraze Supporting Sites can be found on the About EverGraze Demonstration page, and in the EverGraze Quickchecks Guide. Measurements at this site were as follows:

  • Soil tests
  • Production – livestock grazing days (DSE/ha)
  • Pasture condition – availability (kg/ha), composition, ground cover %, perennial species persistence (basal cover)
  • Expenses – capital and variable costs

Key Results

Increased stocking rateThe fescue paddock had an average stocking rate of 16 DSE/ha, despite the paddock being destocked for three months in 2009 due to severe water-logging and seed being harvested in January 2009. Over the same period the annual paddock only carried 11.5 DSE/ha and required double the amount of supplementary feeding to maintain the stock.

Reduced feed costsOver 18 months, stock on the tall fescue required only half the amount of supplementary feed compared to the annual paddock.

Flexible grazing managementThe fescue paddock has helped plug the autumn feed gap, is a great calving paddock as well as being good for maintaining animals over the autumn period. It could also be used to fatten stock provided with the presence of an annual or perennial legume or herb. It is also a fantastic lambing paddock providing excellent protection for stock.

Environmental benefits While some waterlogging still occurs, observations are that this has been reduced. Tall fescue can set roots down to 2.5m which enables the plant to reduce recharge by about 30 mm or one third compared to annual ryegrass. Tall fescue also has a dense plant crown and so there is reduced pugging in wet conditions.

Ground cover has been excellent at almost 100% compared to only 70% in the annual pasture. This has protected the paddock from any possible erosion, from either wind or water.
