Meet Jet and Emma, HSC students from the south coast of NSW having a 'dairy' good time. Update: Jet and Emma recently won a Landcare Champions of the Catchment Education Award. Congrats!


  • 1. GettingDown andDirty on the dairyfarm with Emma& Jet

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. Hi Im Jet HiIm Emma 4. What are Emma and Jet going to talk about today?They are going to tell everyone how the farmer fertilises thepastures and looks after the environment so wehave plenty of lush green grass to eat to help us produce lots of high quality milk 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 grassper day 6. Since the cows use the same laneways to get to the dairy each day 7. and stand in the yards waiting to get milked, a lot of manure collects on the same parts of the farm. 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 9. Adapted from How Now Aussie Cow booklet Dairy Australia 10. Wise use of this manure is a good thing as it contains lots of goodness and nutrients that the cow hasnt had time to digest. Just think our manure feeds the soil Amazing !!!!!!! The soil feeds the grass and the grass feeds us 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. This is a map of our farm showing the levels of soil carbon in our paddocksRed = very high pink = high High soil carbon is a good thing isn't it??Learn all about it Read more: 13. Look what You grow lots and happens when lots of yummyyou spread short sweet grassfertiliser and short sweet grass mean we canproduce lots of milkand less methane!!! 14. Wise farmers recycle the manure and urine collected inholding ponds around thedairy. This waste is used toirrigate and fertilise (feed) pastures helping them grow. 15. On our farm weEmma hosing out recycle 50% ofthe water we use to produceour milk. 16. What sorts of fertilisers arethere??To help the grass grow lushand sweet the farmer alsopurchases and spreadsinorganic and organic fertiliser. 17. We use two types of organic fertiliserOrganic fertiliser isat Clover derived from animal Hill or vegetable matter.DairiesThe first one you have alreadyseen and the other one ispoultry manure 18. Look at They are our fluffycalledchooks Silkies 19. Our silkies produce lotsof manure 20. Truckloads in fact which we recycleand spread over our farm 21. We use a contractor to spread ourpoultry manure and lime. Hi Im His name is Dave. DaveHere he is looking at thenutrient map with Michael thefarmerHi Im Michael 22. Fertiliser is very expensive.How should we To use it in a cost effective and use fertiliser wisely environmentally sensitive way wisefarmers test soil nutrient levels and only apply fertiliser to the paddocksthat need more nutrients. No guess work on this farm! 23. Nutrient maps very highhighadequatelowvery low 24. Nutrient Management Plan A nutrient management plan is a set of conservationpractices designed to use fertilizer and/or manureeffectively while protecting against the potential adverseimpacts of manure, erosion and organic by-products onwater quality. To create the plan we: Soil test Manure test Practice erosion control Manage soil for pH Time fertilizer/manure application. Link is 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. 2. 26. Dont worry youMmh this organicwont even notice in fertiliser may be a couple of days good for theand the grass will environment but itsbe all green anda bit on the nose.lush. 27. Is soil pH important?? The pH of soil or more precisely the pH of the soilsolution is very important because soil solutioncarries 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 thesoil pHLink 28. This is the pH map of our farm pink = very good almost neutral Green = acidic but still very good for growing pastureBlue = acidic and needs attention Yellow = far too acidic and needs alot of attention 29. Hi . Dave back again loading the truck upwith lime. 30. This is paddock 51 on our farm covered in lime 31. Lime leaves the pasture looking like snow has fallen. Rain soon washes it into the soil. Oh my golly gosh I need to paycloser attention to the weather reports. Look its snowing over there !!!! 32. We also use different types of inorganic fertiliser on our farmto grow short sweet grass. 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. On our farm we mostly spread urea Want to know how they make fertiliser 35. We put inorganic fertilisers on the paddock with aspreader attached to the back of the tractorThis ensures evenspreading 36. very highNutrient maps highadequatelowvery low This map shows the levels of P on our farm Which paddockswould you put super phosphate on ?????? 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. 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. How does Nitrogen get into water ways Source: Soil/Managing-farm-nutrients/Managing-farm-nitrogen/ 40. I dont like the look of that water . Do you ??????It smells !!!!!!!!! 41. Hey dont drink out of thereLook how clean it is!!! Lets make sure we helpkeep it that way for theducks. Lets go and find a trough to drink out of. 42. Fertiliser Management Strategies Its no laughingmatterImage 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. Nitrogen Cycle This is laughingGas (nitrous oxide) 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 outand only apply what you need, where youneed it and not when rain is going tobucket down. 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'tthe only bad guy. Did you walk towork today? 47. Healthy soils and clean waterways means happyhealthy cows 48. Visit our new Website 49.
