Winter salad for the livestock

/in , , , /by

With the onset of shorter days and cooler weather, soil temperatures are dropping too and in our region that means the growth of native pasture slows markedly.

This niche, created by a dormant winter pasture, is being exploited by landholders participating in Watershed Landcare’s ‘Pimp My Pasture’ project to grow a fodder crop.

Participating landholders planted multiple fodder crop species in autumn, utilising a technique where crops are planted directly into the dormant pasture, or Pasture Cropping.

As well as providing livestock feed over the winter feed gap, Pasture Cropping has many advantages over conventional techniques, as ground cover and soil structure are not only maintained but improved.

Using direct drill or zero till seeding equipment is beneficial for poorly structured soil and encourages water infiltration. Utilising multiple species also enhances soil structure and paddock species composition.

Pasture Cropping in less productive paddocks, with fewer perennial species can be used to increase the perennial species in the summer pasture. In paddocks with poorly structured soil, Pasture Cropping can improve soil structure, soil health and water infiltration.

The project paddocks were grazed heavily pre-sowing to remove some of the tall grass and create mulch on the soil surface. The purpose of the heavy graze was to remove weed species and create mulch from the standing grass, by using the animals to lay the grass onto the soil surface. The animals also removed the green leaf material from the plants which, in turn, pruned the plant roots. This removes competition for the, soon to be sown crop, from above ground and below. The dying plant roots also add decaying material and nutrients to the soil.

The animals also add manure and urine, which, when combined with plant litter creates a composting layer on the soil surface.

There are many advantages in using a combination of forage species instead of a single species sown as a monoculture: better quality stock feed (faster fattening, less or no scouring); improvements in soil structure; improvements in soil health; good nutrient cycling; balance soil carbon/nitrogen ratio; attracting beneficial insects.

For this project a mix of annual forage species (oats, vetch, field pea, daikon radish, tillage radish, forage brassica and turnip) was planted. This mix is beneficial for improving soil structure, nutrient cycling, and produces good stock feed.

The multi-species pasture crops are growing well and will be grazed over the coming months. The ‘Pimp My Paddock’ project participants will be monitoring whether this helps to enhance pasture management and increases paddock rest times over winter.

Working on erosion solutions

/in , , /by

As part of the ‘Digging Deeper into Watershed Soils’ project local landholders had the opportunity to explore soil health issues within our region at a series of workshops held last week.

Watershed Landcare invited David Hardwick, Agricultural Ecologist and soil guru, to provide his expertise on some common erosion issues, their causes and solutions, and to provide participants with an understanding of how to implement these solutions and improve the soil health on their own patch.

The workshops focused on improving soil health, the aspects which influence it, and adapting management decisions as a result of understanding the landscape.

One of the properties visited was Karrabool Olives where the owners, David Sargeant and Judy Rogers, wanted to repair erosion and degraded soil in their olive grove. They also wanted David’s insights into how to improve soil fertility for the olives.

The olive grove was planted on the side of a hill, with rows down, rather than across, slope. The top of the hill is poor, gravely soil and supports only some scraggly native vegetation. Runoff is causing sheet and rill erosion through the olive grove.

David’s suggestions included a number of measures to slow the flow of water at the top of the hill. These included putting in a rip line along the fence at the top, allowing the native vegetation to re-establish and utilising olive prunings as a physical barrier to further slow the flow of water at the top of the hill.

Dissipating the water in the olive grove was also an important consideration and the field day participants got their hands dirty, learning how to construct small rock structures to slow and fan out the water flow along the rows of olives.

A soil pit dug to look at the soil structure in the olive grove indicated a layer of compacted soil.

As a long-term management strategy to improve water infiltration and fertility and reduce compaction, David recommended widening the inter-row vegetation to reduce the bare area under the trees and increasing the diversity, particularly with deeper rooted species as olives have shallow roots.

The tactics suggested by David are easy and relatively low cost options that David and Judy can implement before the problem got much more serious. Addressing issues early, or even preventing them when possible, results in manageable solutions. Over time small problems grow and when we are seeing the site everyday it can be easy to not notice the damage that is occurring. Monitoring of your land is the best way to stay on top off changes in your landscape and help you decide when its time to make a change in the way you mange an issue or erosion site.

What helps the environment, saves money and feeds the soil at the same time?

/in , /by

Did you know that each year, Australian households generate around 13 million tonnes of organic waste and that about half of that ends up in landfill?

May 7 to 13 marks International Compost Awareness Week in Australia. This is a week during which Australians are invited to pay closer attention to what they put in their rubbish bin and consider that often about half of that could be put to better use.

Compost is not only a valuable organic resource (plants love it and it helps to build healthy soils) but also it reduces the volume of material going to landfill, the associated detrimental environmental effects and makes economic sense too.

Diverting organic materials from landfill and properly composing them can help in the effort to mitigate the effects of climate change by reducing methane emissions and contributing to soil carbon storage.

Organic materials such as food scraps and garden waste breakdown to methane when decomposing without air in landfill conditions. Methane, a greenhouse gas, is 25 times more potent than carbon dioxide so reducing its emissions is an important factor in combating climate change.

Using compost as a fertiliser or soil conditioner returns carbon into the soil, where it can be locked up or utilised for plant growth, rather than being emitted into the atmosphere.

Landfill is the most expensive form of waste management and while it’s free to drop your rubbish off at the Mid-Western Regional Council waste stations, don’t be fooled – as ratepayers we fund the operation and maintenance of these facilities.

The existing landfill cell at the Mudgee Waste Depot will reach capacity within 10 years. As space runs out and alternatives need to be sought, costs are likely to increase. So reducing the amount of organic waste going in will prolong the life of the existing landfill site and reduce the costs long term.

Composting reuses food waste and nutrients are recycled into fertiliser. By applying compost to gardens, farms and other land uses, nutrients are returned to the soil to feed diverse soil life. The bacteria, fungi, insects and worms in compost support healthy plant growth, rather than letting organic waste rot away in landfills.

So start a compost heap (or worm farm or get a few chooks to take care of the scraps), reduce waste and your carbon footprint. Happy composting!

The secret life of your kitty

Ever wondered what your cat gets up when you’re not looking? What if you could keep track of your cat’s whereabouts even when you’re not around? Now is your chance to get a unique insight into your cat’s habits.

Central Tablelands Local Land Services and Mid-Western Regional Council invites you to take part in the Domestic Cat Tracking project.

The project, which involves fitting a small, lightweight GPS tracker to cats and monitoring their movements for 11 days, has already been rolled out in Orange and Lithgow and is now coming to Mudgee.

The Cat Tracker Project aims to find out where cats venture to and to promote awareness of the distances that domestic cats can travel. It will also give a better understanding of the time spent away from home and the location of the cats when they roam.

Cats and their humans from Mudgee, Gulgong, Rylstone and surrounding farms and peri-urban areas are invited to join the program.

The participating cats will wear a small motion-sensored GPS tracker, fitted to a harness for a maximum of 11 days. The GPS device and harness combined weigh less than 50g and the harness is fitted with a a breakaway safety buckle to prevent cat becoming caught or snagged on an object.

The information collected by the GPS trackers will be downloaded and overlayed onto mapping imagery. This will be provided to the cat owner so that they can identify where their cat has travelled.

You can view results from a similar project run in South Australia at: http://www.discoverycircle.org.au/projects/cat-tracker/tracks.

Want to find out more about the project or how to get involved?

An information and registration session will be held on Thursday 18 May at 6pm at the CWA Rooms, 48 Market St, Mudgee.

For more information or to register please contact Julie Reynolds, Central Tablelands LLS Land Services Officer, on 6378 1706 or 0418 150 1676 or by email: julie.reynolds@lls.nsw.gov.au.
