Sustainability in action at our school farm

Sustainability focus lesson


Composting - a great way to enrich soil with organic matter and nutrients whilst reducing landfill waste.




This week at the school's farm, we learnt about the importance of composting to food production systems. Composting not only reduces landfill waste but also allows natural decomposers to recycle waste material into rich organic matter that improves soil quality and promotes healthy plant growth.

The better the soil, the better the plant growth whether it is a food crop or pasture for animals to graze on.

We learnt about the importance of the ratios of carbon and nitrogen that are needed to get the composting system to the right temperature and gave our three compost bins the necessary water and ratios to get them working well.

 
 
 
Watch our first video showing us in action. We decided to post our first video even though the footage is a bit shaky because we are sure that our filming will improve and we want to show how much we will learn on our Archiibull Prize journey.

Program Launch at Kiama


Deborah, Marni and Ms Hargraves travelled up to Kiama this week to experience the launch of the Archibull Prize program for South Coast schools. We are pictured here with the Mayor of Kiama and learnt that the Kiama Council has been very supportive of the program which is now in its third year. Lynne Strong's farm Clover Hill Dairy is located nearby at Jamberoo and Lynne is an active community member in the Kiama area.

It was very helpful to hear what the art judge Wendy Taylor had to say about what she is looking for when judging the artworks.
 

Challenges farmers face - Compulsory Blog 2

Documenting our learning journey - looking at the challenges that farmers face

There were so many resources linked to the program for this compulsory blog topic that we thought the best way to deal with all of the information was to split into smaller working groups, with each group reading and summarising the key points in the sources. Then we got back together and created a mind-map about the challenges that farmers face

Before we did that we watched some videos together in the lab.

 

CLIMATE CHANGE - a BIG challenge for all of us

agriculture climate change sceptics 600 | nicholsoncartoons.com.au


We all agreed that one element that all farmers cannot control is the climate. Farmers in Australia are often at the mercy of long-term weather patterns such as drought and short-term weather events such as floods.

However research from the Primary Industries Climate Challenges Centre at the University of Melbourne surveyed only 28% of primary producers as accepting that human activity is the cause of climate change compared with 58% of people in cities.

The Director of the centre says that the science tells us that no matter what farmers believe, agricultural production is at risk from climate change as well as being a significant contributor to greenhouse gas emissions.

Reliable rainfall and predictable ranges of temperature are critical to farmers but are also the factors that will be most affected by climate change. Farmers may have to adapt to the way they farm to meet the changing climate in one of three ways:

1. Adjusting their current practices in small ways such as crop and pasture varieties and the timing of activities,
2. Changing from singular to mixed farming systems, changing products or markets which has seen grain crops grown in areas that were previously too wet in winter,
3. Making large scale transformational changes  that could involve new industries and products

We found a good video from the ABC Midday Report called 'Warmer temperatures to offer new opportunities to farmers'. "CSIRO climate applications scientist Steve Crimp says the nation's agricultural sector will likely feel the heat of a hotter climate." You can watch it at this link:

Pricing Carbon and Carbon Farming

The Federal Government's CLEAN ENERGY FUTURE policy has placed a price on carbon emissions. This can impact on farmers in direct and indirect ways but ultimately drives farm running costs up. The Carbon Farming Initiative offers farmers an incentive to reduce emissions and/or store carbon and the potential to earn farm income to offset some of the increased costs associated with the carbon tax.

 
We also looked at the transcript of an ABC Local Radio story reported by Sarah Clarke on 1/11/12 titled:
"Farming smarter not harder to profit from food boom".

As we look to 2050 and a world population of some 9 billion people to feed it is estimated that Australia is well placed to profit from this food demand increase of 60%, by earning around $16 billion more from agriculture than we do now. As global demand and prices for food increase, there will be new market opportunities for Australian agriculture. The story highlights again that this is only possible if Australian farmers prepare for climate change which could reduce our agricultural production by up to $6.5 billion a year if we do not start to innovate now.
The two big things that we need to address in preparation for the future in terms of food production, are more frequent droughts and improving our soil quality. Australia is dominated by highly infertile soils that are a product of our tectonic stability and ancient geology. Our soils are also very easily eroded and farmers need to maintain as much groundcover to prevent these soils from being eroded. We think that there could be a composting revolution in Australia that could see our soil fertility and agricultural production improve dramatically.

How can technology help farmers face the challenges they face?

Farmers can access climate applications such as the CliMate App which allows users to interrogate the climate data and apply this to Agriculture.

Climate information can be accessed at the Bureau of Meteorology website which also has a section specifically for agriculture where farmers can look at forecasts for rainfall, cloud, temperature, wind and longer term forecasts for El NINO and LA NINA systems using the Southern Oscillation Index that are related to drought. This allows them to plan for the short and long term weather conditions.

There is an Australian company called Precision Agriculture that provides a number of technological tools for primary producers to use.

Precision Agriculture starts with an accurate digital farm map, then other information is built around this map.
There are satellite image maps at different resolutions that can see every little detail about the crop to see the impact of micro-variation on crop productivity. This satellite product is also good for evaluating trials. iSAT5 – has the red-edge included, which may give new insights into crop health. This imagery is useful for zoning and in-crop applications of crop protectants, nutrients, and even desiccation where appropriate. They can do a whole farm or catchment relatively cheaply with. Its primary use is it to examine long-term trends over the property or catchment.
Yield monitors and farm works software programs allow farmers to manage their properties more profitably. Different modules can be selected according to the farmer's needs.
Elevation/Topography Mapping and Drainage
Elevation is one of the most critical layers in Precision Agriculture. It can determine waterlogged areas, erosion risk, drainage restrictions, and often is related to soil type.
Electromagnetic (EM38) soil mapping
EM38 soil mapping is used by Precision Agriculture as a reliable option for zoning paddocks according to soil type and potential yields. It is a fast and cost effective way of measuring soil moisture content, salt levels, and soil texture (clay content).
Controlled Traffic Farming
Research and on-farm experiences suggest that continuous cropping systems perform extremely well under a zero till, controlled traffic farming stubble retention farming system. Controlled Traffic Farming is a healthy cropping system, which delivers production, environmental, and efficiency benefits. It separates paddocks into two sections:
  1. one which provides a healthy well structured soil for promoting crop growth, and
  2. one which provides a roadway for supporting vehicles and machinery.
Solar powered remote camera systems allow farmers to get a view of their crop, animals, assets, water troughs etc… from anywhere in the world via email or the internet.

We are going to devote a separate blog to the specific challenges that dairy farmers face and how technology can help them.

Introducing...Udder Brilliance

Udder Brilliance was named on the 21/5/2013 after much discussion and a very diplomatic voting session. Before we decided on the best name for her out of a long list of possibilities, we showed her around the school and she had a wonderful time checking out the library, the office and the agriculture farm. She loved the sheep!

Making the most out of waste 





 

During one of our first theory lessons we looked at an article on effluent re-use on dairy farms.

Nutrients are lost from the soil when cows feed on pastures, these nutrients can be replaced by purchasing high cost fertilisers or collecting effluent (cow manure and urine) to re-apply to paddocks.

Effluent is rich in nitrogen, phosphorus, potassium and organic carbon which are all necessities for healthy pastures. This is a sustainable way for replacing lost minerals from the soil without having to increase the cost of cash inputs. This also reduces CO2 levels in our environment.

 It is important not to waste nutrients on a farm. Cow manure can be converted into liquid fertiliser and applied to pastures to promote growth, it also allows the re-use of effluent to be recycled through the farm's ecosystem which can often include or lead to more than just cattle and grass

Effluent is rich in nitrogen, phosphorus, potassium and organic carbon. It provides nutrients for the plants that make up the pasture that the animals feed on. Effluent re-use allows Carbon and Nitrogen to be recycled through the farm's ecosystem which can often include more than just cattle and grass.

 Benefits of recycling effluent on Dairy Farms

  • Correct application of effluent will boost pasture production.
  • Possible cost savings through reduced need for fertiliser.
  • Effluent can be an excellent soil conditioner (a source of organic carbon).
  • Containing nutrients and sediment on-farm reduces contamination of waterways.
  • Reduce spread of animal and human disease (by eliminating waterway contamination of the harmful bacteria in effluent).
  • Conserving water by recycling and/or reducing amount used (amount depends on size of alleys, yards, etc, and the quality of cleaning).
  • Well-designed, constructed and maintained tracks will assist in reducing lameness, promote good udder hygiene and improve stock traffic flow.
  • Capturing nutrients from laneways and redistributing them on-farm provides a source of nutrients.


  • UNACCEPTABLE PRACTICEACCEPTABLE PRACTICEABOVE ACCEPTABLE PRACTICE

    No system to collect effluent. This could result in effluent leaving the property in ground and surface waters.

    Effluent being applied by a sprinkler system. Applying effluent correctly maximises nutrient use and minimises nutrient run-off from the farm.

    A two-pond system allows flexibility to store over the wet months (reducing the chance of run-off). Effluent can be applied to pastures when they are actively growing (maximising nutrient benefit) and there’s the opportunity to recycle for yard wash-down.



    Sweetie Meaty Pie says this is a sustainable practice that all farmers should consider implementing on their farms.

    NEWS FLASH>>>>>> from the Dairy Diaries

    Large fibreglass cow causes a ruckus at Shoalhaven High School
    The cow was seen at the school's office chatting to the  ladies who organised a 'special' enrolment for her.

     
    At the school's farm the resident cow Creamy was heard mooing loudly.
     

    
    Students reassure Creamy that she is not experiencing de ja vu.

    The blank cow felt much more comfortable after meeting another of her breed; "Sweetie Meaty Pie"


    The students took the cow to the school library and explained to her that she is a dairy cow and that her milk can be used to make many food products.



     
    Many students at the school have signed up to be part of the 2013 Shoalhaven High School Archibull Prize Team. Their focus industry is Dairy.
     
    The Archibull Prize is a competition that allows students to creatively express their understanding of where our food comes from and how farmers face many challenges to be able to sustainably feed the populations of the future.
