Richard.Rawnsley@utas.edu.au

Dr Richard Rawnsley is the Dairy Centre Leader with the Tasmanian Institute of Agriculture (TIA). Richard has worked for the TIA Dairy Centre for eleven years and his main research interests are pasture and forage agronomy, biophysical modeling and farm systems research.

Richard is the lead researcher on the Beyond 2012 project, a Tasmanian-based initiative managed by the TIA Dairy Centre, University of Tasmania, and funded by Dairy Australia. The project is focused on developing a greater understanding of the key grazing principles of temperate pastures and optimising pasture performance, pasture consumption and farm profitability. The project aims to develop adaptive practices and technology for pasture base dairy systems to meet future challenges including the integration of complementary forages.

Career summary

Qualifications

  • PhD, 'A Study of the Biology and Control of Anthriscus caucalis and Torilis nodosa in Pyrethrum,' University of Tasmanian, 2004

Biography

Richard completed his PhD at the University of Tasmania in 2004, studying the biology and control of Anthriscus caucalis and Torilis nodosa in Pyrethrum. He has been an active research scientist with TIA for 11 years, including 4 years as Dairy Centre Leader. Richard has over 130 research outputs (including peer-reviewed publications, book chapters, conference papers, and research and consultancy reports), and over 40 successful research grants (18 as lead investigator) with a cash value of over $7million. He is actively involved with the Dairy industry, sitting on numerous Boards, and steering and reference groups that direct the future of the industry.

Research Themes

Richard's research aligns with the University's research themes of Environment, Resources and Sustainability and Data, Knowledge and Decisions. His research interests include pasture optimisation (yield and growth of perennial ryegrass in particular); climate change and its effects on pasture, forage and livestock, and how to adapt for future warmer and drier climates; and developing sensing and modelling tools for use by industry to maximise farm outputs.

As part of a Sense-T project funded by the state and federal governments, Richard, along with Dr David Henry from CSIRO, has developed an online tool, the Pasture Predictor, which uses data from the weather bureau, past climate records, rainfall events and soil moisture to predict pasture growth over a 30 to 90 day period. The predictor is aimed at beef and dairy farmers but is also suitable for cropping enterprises.

The Pasture Predictor looks at seven sites around Tasmania, from Smithton in the far north-west to Scottsdale in the east and Ouse in the Derwent Valley. Sense-T is also looking at rolling out the Pasture Predictor in other Australian states and will also look at predictions for different farms as the model is refined.

Current projects

Boersma, M; Rawnsley, RP; Gracie, AJ. (2014 - 2017). Short Term Effluent Retention. DAFF: Grant-Carbon Farming Futures - Action on the Ground. $306,785.

Three-quarters of Australian dairy farms store effluent in earthen ponds (Down to Earth Research 2012). During storage, volatile solids settle out of the supernatant onto the sludge layer, decomposing to release methane and carbon dioxide. Research undertaken by Fyfe (2012) indicates that a long solids retention time in anaerobic ponds results in methane generation well over 400 kg CO2-e cow-1 yr-1 which represents over 7% of the total GHG estimate for grazing farms. In pig production systems, emissions from, the frequent removal of volatile solids FSA (2012) is estimated to reduce methane emissions by up to 72% which, if applied to a dairy system, may be analogous to 5% of dairy farm GHG emissions.

This proposal seeks to demonstrate and evaluate a short effluent retention time strategy on a Tasmanian dairy farm. The project will also demonstrate an above ground tank system suitable for use on light soils where an earthen dam would leak nitrates and other nutrients into the water table. To minimise GHG emissions and maximise the efficiency of returning water and nutrients to the soil, effluent will be distributed on a frequent basis, the frequency determined by soil moisture deficits. Faunal anaerobic respiration ceases once the volatile solids as they dehydrate on the soil surface.  To minimise the risk of off-site nutrient pollution, it is expected that the retention of effluent will be necessary over the winter months. Data collected will include methane emissions, periodic CO2 and N2O emissions, agitator energy consumption (kWh), air temperature, effluent temperature at 4 depths, effluent levels (continuous), effluent flow into and out of the tank, wind speed and direction, rainfall and herd production data.

Harrison, MT; Rawnsley, RP. (2013 - 2016). Dairy Businesses for Future Climates. DAFF: Grant-Carbon Farming Futures - Filling the Research Gap. $1,163,174.

This project combines biophysical and economic modelling, social research and farmer engagement to identify farm management responses and innovations that maintain profitability while building human and biophysical capacity to manage a more variable and challenging future.

Rawnsley, RP; Christie, KM; Harrison, MT; Eckard, R. (2012 - 2015). Whole farm systems analysis of greenhouse gas abatement options for the southern Australian grazing industries. DAFF: Grant-Carbon Farming Futures - Filling the Research Gap. $537,902.

This project will conduct whole farm systems analysis of a range of nitrogen, carbon and energy efficiency and greenhouse gas abatement strategies for the dairy, sheep and southern beef industries. Strategies will be drawn from reviews and current research, as directed by an Investor Steering Group. Each strategy will be analysed in a whole farm systems context, including methane, nitrous oxide, soil carbon and productivity, plus the interactions between these. The outcomes from the project will be a series of biophysically and economically evaluated options for reducing emissions intensity, improving farm profitability and/or further development into Carbon Farming Initiative offset methods.

The objectives of this project are to:

  • establish and collate a body of knowledge for perennial forbs and legume forages that matches that of perennial ryegrass with respect to the seasonal growth patters, DM yields, nutritional profile, grazing management and feeding practices
  • develop the capacity to accurately model the growth and development of perennial forbs and legume species and to evaluate the influence on the whole of farm system from the incorporation of these forages within the pasture base system
  • complete the development of integrated forage systems for dairy businesses in the temperate environment of Australia that are predicted to result in results of higher levels of milk production per cow from high rates of consumption of home grown forage
  • develop integrated forage systems for dairy businesses in the temperate regions that are predicted to achieve greater level of profitability whilst improving the environmental footprint of the farming system
  • in partnership with the TIA dairy centre extension team and other extension providers, co-develop a dissemination approach of knowledge regarding the incorporation of perennial forage options within the farming system in the temperate regions of Australia

Description
: The Tasmanian Dairy on PAR project will contribute towards achieving the Dairy Moving Forward (DMF) vision of profitable, growing, sustainable, rewarding dairy farms. The project utilises the RD&E expertise of the TIA Dairy Centre in addressing the three high level objectives for improved feedbase performance in pasture based dairy systems: increasing pasture consumption by 0.05 to 0.1t DM/ha per 100mm of water received (equivalent to 0.75 to 1.5t DM/ha increase); understanding the plant/animal/feeding interface to enhance individualised feeding decisions that increases the marginal milk response of concentrate feeding by 20%; and growing industry skills, knowledge and confidence in business analysis and risk to increase operating profit (EBIT) by $0.1 kg MS. This project also recognises that a technological shift associated with milk harvesting in the form of automatic milking system (AMS) creates a new dynamic that must be considered and incorporated into any new activities

Evaluation of the effects of grazing regime on root C and N reserves of winteractive lucerne grown in a temperate climate (2015)$2,500
Description
Hypothesis (HO):The frequency and pattern of defoliation (grazing) events over the growing period(spring/summer/autumn) will not affect the persistence of a luceme stand.Research Objectives:This study will attempt to determine whether the findings of Teixeira et al. (2007) hold true for anestablished winter-active luceme crop. The ultimate aim of the study is to better define the bestmanagement practices for defoliation of luceme in south-eastern Australian dairy systems, andconsequently reduce the barriers to lucerne uptake.

Simulating pasture growth rates for use in whole farm dairy models (2014)$2,451
Description
The project will model the regional pasture growth data for four Tasmanian dairy regions under both rain-fed and irrigated conditions. The four sites are; Woolnorth, Togari, Edith Creek and Trowutta. DalryMod a mechanistic biophysical model developed for the Australian dairy Industry will be used to simulate the regional pasture growth Information. The model uses daily weather information and includes soli water, soil nutrient, pasture growth, and animal production modules. It is proposed that a formalised contractual arrangement for the ongoing request for biophysical modelling of pasture growth rate data be established with Intelact Ltd. This would be on a daily rate basis with number of days determined by the request.

An evaluation of the effect of feeding Megalac rumen-protected fat in a pasturebased dairy system in Tasmania (2013)$60,770
Description
The addition of protected fats to a cows diet are thought to have a positive effect upon many aspects of productivity and reproductive performance as, among other attributes, they may provide an increase in the energy available to the cow. Megalac protected fat is not degraded in the rumen but passes through to the small intestine where it is degraded, providing energy directly to the cow. Protected fats also allow for an increase in the fat content of the diet above that normally considered safe as they bypass the rumen and therefore do not affect absorption rates by the rumen papillae. There is a paucity of information on the role and effect of protected fats in pasture based dairy systems. The majority of referenced work has concerned the role of protected fats in the TMR and high input dairies.

Short Term Effluent Retention (2013 - 2017)$632,000
Description
Three-quarters of Australian dairy farms store effluent in earthen ponds (Down to Earth Research 2012). During storage, volatile solids settle out of the supernatant onto the sludge layer, decomposing to release methane and carbon dioxide. Research undertaken by Fyfe (2012) indicates that a long solids retention time in anaerobic ponds results in methane generation well over 400 kg CO2-e cow-1 yr-1 which represents over 7% of the total GHG estimate for grazing farms. In pig production systems, emissions from, the frequent removal of volatile solids FSA (2012) is estimated to reduce methane emissions by up to 72% which, if applied to a dairy system, may be analogous to 5% of dairy farm GHG emissions. This proposal seeks to demonstrate and evaluate a short effluent retention time strategy on a Tasmanian dairy farm. The project will also demonstrate an above ground tank system suitable for use on light soils where an earthen dam would leak nitrates and other nutrients into the water table. To minimise GHG emissions and maximise the efficiency of returning water and nutrients to the soil, effluent will be distributed on a frequent basis, the frequency determined by soil moisture deficits. Faunal anaerobic respiration ceases once the volatile solids as they dehydrate on the soil surface. To minimise the risk of off-site nutrient pollution, it is expected that the retention of effluent will be necessary over the winter months. Data collected will include methane emissions, periodic CO2 and N2O emissions, agitator energy consumption (kWh), air temperature, effluent temperature at 4 depths, effluent levels (continuous), effluent flow into and out of the tank, wind speed and direction, rainfall and herd production data.
