Video: How to use fertiliser N successfully – Lee Menhennett, Incitec Pivot Ltd.

At what price is there a place for bagged N in pastures (beef/cattle)?

  • If additional nitrogen is being supplied as fertiliser – what application rates should be used, how many applications per year, when should these applications occur (timing, growing conditions) and which pastures should be targeted?
  • Is there any role for using soil testing to monitor N levels in pastures and, if so, how do we make it accurate?
  • What are the environmental implications of increasing nitrogen levels in a perennial pasture system and how to minimise them? N losses, denitrification, leaching.

Video: Maximising legume N contribution in mixed pastures- Dr Belinda Hackney, NSW DPI

How much N do we get from clovers and when?

  • If relying on legumes in the pasture system to supply the required nitrogen, how can nitrogen fixation be maximised?
  • If using both N fertiliser and clover, what rules apply to maximise production & profit?

Video: How to maximise the potential gains from N in perennial pasture systems? – Lisa Warn, Ag Consulting

How important is nitrogen in terms of improving pasture growth?

  • Pasture nitrogen requirements – how much is needed?
  • N cycle - when is N supplied & when is it deficient? How do clovers and organic nitrogen fit into the cycle?
  • What is the speed of the N cycle through mineralisation and what affects this rate?
  • What yield advantage can be gained by supplying more nitrogen to perennial pastures?

Video: Healthy Soils Webinar – Session 3 Soil Organic Carbon

Presenter Dr Susan Orgill, NSW DPI addresses the following scenario: Carbon, it’s all that’s talked about. My kids want me to do something to help the environment and there seems to be lots of benefits in improving soil carbon and I don’t want to miss out if there is money to be made from carbon trading. But I hear it’s tricky to tell if you are actually making a difference and to do this you need to monitor over a long time or test carbon fractions. I’m not sure that my carbon levels are even that bad and that its worth lifting them. How do I even tell and if I do try and improve, what’s the best way to improve soil carbon? The neighbours are putting on compost and I have heard about special pasture renovators and even biological stimulants to increase soil carbon.

Video: Healthy Soils Webinar – Session 2 Soil Acidity

Presenter Dr Jason Condon, Charles Sturt University addresses the following scenario: Some of the soil experts are saying that our current liming topsoil pH targets are much too low and won’t stop subsurface acidity from forming. But liming is expensive and producers/advisors are unsure if they can justify spending money on more lime, especially when lime is not the only limiting factor. Plus, it doesn’t look like the lime is moving, so is it worth it? Are these new targets just for “good country,” and protecting sown pastures, what should producers do about poor pastures or hill country? If producers already have acid subsoils, should they just live with it or try to fix them. Plus aren’t soils naturally acid anyway, is it such a big deal?

Video: Healthy Soils Webinar – Session 1 Fertilisers

Presenter: Dr Mark Farrell, CSIRO addresses the following scenario: Healthy soils are the foundation of a productive and profitable grazing system. In the past the focus on achieving a healthy soil and pasture has been meeting sufficient levels of available nutrients by fertilising. However today some producers are querying the response they are getting from their traditional fertilisers given the money they spend; fertiliser just doesn’t seem to work like they used to. Understandably many question if they are getting good value for the fertiliser investment. When combined with recent discussion around achieving balanced soil condition, holistic soil management, feeding the soil bugs and ‘natural’ fertilisers, it is not surprising many of us are wondering what’s the right way to go.
