Grow Grass Grow - dairy farming with Jet and Emma

  1. 1. Getting Down and Dirty on the dairy farm with Emma & Jet www.slideshare.net/LandLearnNSW
  2. 2. Emma and Jet • My name is Emma I am 16. As part of my HSC I am doing a dairy traineeship at Clover Hill Dairies • My name is Jet. I am also doing a dairy traineeship with Alan and Leesa Swan at Hillview Dairy
  3. 3. Hi I’m Jet Hi I’m Emma
  4. 4. What are Emma and Jet going to talk about today? They are going to tell everyone how the farmer fertilises the pastures and looks after the environment so we have plenty of lush green grass to eat to help us produce lots of high quality milk
  5. 5. Lets start at the beginning • Cows eat a lot of grass per day - over a wheelbarrow load - which means they produce a lot of manure. 100kgs grass per day
  6. 6. Since the cows use the same laneways to get to the dairy each day
  7. 7. and stand in the yards waiting to get milked, a lot of manure collects on the same parts of the farm.
  8. 8. Cows help move nutrients around the farm. When they graze they pick up the nutrients in the grass in one paddock and spread them to the next paddock they graze after milking. Link www.dpi.nsw.gov.au/agriculture/resources/soils/improvement/plant-nutrients
  9. 9. Adapted from How Now Aussie Cow booklet – Dairy Australia
  10. 10. • Wise use of this manure is a good thing as it contains lots of goodness and nutrients that the cow hasn’t had time to digest. Just think our manure feeds the soil Amazing !!!!!!! The soil feeds the grass and the grass feeds us
  11. 11. • This goodness includes organic matter which helps build soil carbon and keep moisture in the soil. • Manure also contains nitrogen, phosphorus and potassium, nutrients or foods which help plants grow.
  12. 12. This is a map of our farm showing the levels of soil carbon in our paddocks Red = very high pink = high High soil carbon is a good thing isn't it?? Learn all about it here www.csiro.au/resources/soil-carbon Read more: www.amazingcarbon.com/PDF/JONES-Carbon&Catchments(Nov06).pdf
  13. 13. Look what You grow lots and happens when lots of yummy you spread short sweet grass fertiliser and short sweet grass mean we can produce lots of milk and less methane!!!
  14. 14. Wise farmers recycle the manure and urine collected in holding ponds around the dairy. This waste is used to irrigate and fertilise (feed) pastures helping them grow.
  15. 15. On our farm we Emma hosing out recycle 50% of the water we use to produce our milk.
  16. 16. What sorts of fertilisers are there?? To help the grass grow lush and sweet the farmer also purchases and spreads inorganic and organic fertiliser.
  17. 17. We use two types of organic fertiliser Organic fertiliser is at Clover derived from animal Hill or vegetable matter. Dairies The first one you have already seen and the other one is poultry manure
  18. 18. Look at They are our fluffy called chooks Silkies
  19. 19. Our silkies produce lots of manure
  20. 20. Truckloads in fact which we recycle and spread over our farm
  21. 21. We use a contractor to spread our poultry manure and lime. Hi I’m His name is Dave. Dave Here he is looking at the nutrient map with Michael the farmer Hi I’m Michael
  22. 22. Fertiliser is very expensive. How should we To use it in a cost effective and use fertiliser wisely environmentally sensitive way wise farmers test soil nutrient levels and only apply fertiliser to the paddocks that need more nutrients. No guess work on this farm!
  23. 23. Nutrient maps very high high adequate low very low
  24. 24. Nutrient Management Plan A nutrient management plan is a set of conservation practices designed to use fertilizer and/or manure effectively while protecting against the potential adverse impacts of manure, erosion and organic by-products on water quality. To create the plan we: • Soil test • Manure test • Practice erosion control • Manage soil for pH • Time fertilizer/manure application. Link is www.asris.csiro.au/themes/nutrient.html
  25. 25. What Goes in vs. What Goes Out Nutrient budgeting is used by all good farmers. • The process involves balancing nutrients coming into the farming system with those leaving. • The aim is to prevent pollution events and save costs by precisely matching the nutrient requirements of the crop with application of organic and inorganic fertilizers. Links 1. www.ew.govt.nz/environmental-information/Land-and-soil/Managing-Land-and-Soil/Managing-farm-nutrients/ 2. www.sardi.sa.gov.au/__data/.../fact_sheet_1404_nutrient_budgeting.doc
  26. 26. Don’t worry you Mmh this organic wont even notice in fertiliser may be a couple of days good for the and the grass will environment but it’s be all green and a bit on the nose. lush.
  27. 27. Is soil pH important?? The pH of soil or more precisely the pH of the soil solution is very important because soil solution carries in it nutrients such as Nitrogen (N), Potassium (K), and Phosphorus (P) that plants need in specific amounts to grow, thrive, and fight off diseases. Coastal soils tend to be acidic and farmers spread Calcium hydroxide (lime) to raise the soil pH Link http://soil.gsfc.nasa.gov/soil_pH/plant_pH.htm
  28. 28. This is the pH map of our farm pink = very good almost neutral Green = acidic but still very good for growing pasture Blue = acidic and needs attention Yellow = far too acidic and needs a lot of attention
  29. 29. Hi . Dave back again loading the truck up with lime.
  30. 30. This is paddock 51 on our farm covered in lime
  31. 31. • Lime leaves the pasture looking like snow has fallen. • Rain soon washes it into the soil. Oh my golly gosh I need to pay closer attention to the weather reports. Look its snowing over there !!!!
  32. 32. We also use different types of inorganic fertiliser on our farm to grow short sweet grass.
  33. 33. Want to know more…. Both natural and man-made fertilisers are measured by the three MAJOR Nutrients that are in them. These are: - • Nitrogen (N) - assists plants with leaf and stem growth. • Phosphorus (P) known as PHOSPHATE - assists young plants and root crops to develop good root systems. • Potassium (K) known as POTASH - assists plants to produce flowers and fruit.
  34. 34. On our farm we mostly spread urea Want to know how they make fertiliser www.slideshare.net/chalkie28/making-fertiliser
  35. 35. We put inorganic fertilisers on the paddock with a spreader attached to the back of the tractor This ensures even spreading
  36. 36. very high Nutrient maps high adequate low very low This map shows the levels of P on our farm Which paddocks would you put super phosphate on ??????
  37. 37. Helicopters Spreading Nutrients • Sometimes on very large farms helicopters are used to spread the fertilisers. • Helicopter pilots have to be very careful to keep well away from the rivers and stream so the fertiliser doesn't get into our waterways.
  38. 38. Nitrogen Escapes!!!! • It is very important that farmers look after their waterways. • When soil and nutrients fall into rivers, they become murky and it upsets the food balance for all the water-dwelling animals. • Sometimes it encourages the growth of algae that can poison animals.
  39. 39. How does Nitrogen get into water ways Source: www.ew.govt.nz/environmental-information/Land-and-soil/Managing-Land-and- Soil/Managing-farm-nutrients/Managing-farm-nitrogen/
  40. 40. I don’t like the look of that water . Do you ?????? It smells !!!!!!!!! www.toxics.usgs.gov/definitions/eutrophication.html
  41. 41. Hey don’t drink out of there Look how clean it is!!! Lets make sure we help keep it that way for the ducks. Lets go and find a trough to drink out of.
  42. 42. Fertiliser Management Strategies Its no laughing matter Image www.usefilm.com
  43. 43. Laughing Gas – not so funny • Nitrous oxide also known as laughing gas or happy gas is a major greenhouse gas and air pollutant. • Over a 100 year period, it has 298 times more impact per unit weight than carbon dioxide. • Nitrous oxide escapes into the air when nitrogen fertiliser is used. (See next slide)
  44. 44. Nitrogen Cycle This is laughing Gas (nitrous oxide)
  45. 45. Fertiliser – the aim of the game… is to keep the nutrients on the pasture and out of the airways and waterways. So its very important to: measure what goes in and what goes out and only apply what you need, where you need it and not when rain is going to bucket down.
  46. 46. Fertiliser Formulations • Like all things driven by need, fertilisers are being developed with protective coatings to reduce the amount of Nitrous Oxide escaping in the atmosphere. Fertiliser isn't the only bad guy. Did you walk to work today?
