The Stewart PIT spoke at length about the data that could be collected on the farm to inform some key management strategies for the group. In the first couple of meetings the watering strategy utilised on the farm, in particular the longer irrigation intervals that Kelvin and Don use, were of particular interest to the other farms in the group. Some felt that the longer intervals might be causing a yield penalty where others were keen to know if they could implement a longer irrigation interval to save on water use without compromising on pasture accumulation. The PIT team discussed the monitoring and measurement methodology and it was agreed that Accelerating Change would measure the impact of different watering strategies on the Stewart’s lucerne and perennial pastures.
The following methodology was agreed to. Each square represents a different irrigation bay.
On the Stewart farm, we are taking regular weekly readings to examine pasture growth at different irrigation intervals and on...
A lot has been happening in the Accelerating Change project and the broader industry over the last month. The hot dry start to spring meant irrigation was well under way when the Stewart Performance Innovation Team (PIT) met on 17 September. With the upturn in water prices, many farmers involved with Accelerating Change are reviewing their summer feeding strategies. Initial data collection will help assist with the calculations to weigh up whether certain pastures will be watered through or dried off. The Stewart PIT met in September to review farm performance, receive a technical presentation on moisture probes from Dale Boyd of DEDJTR and discuss and the monitoring and measurement strategy and pasture reading technology on the Stewart’s farm.
Accelerating Change is using the Automated Pasture Reader (APR) to collect data about the average pasture height, uniformity and estimated mass (kgDM/ha) across selected paddocks. In a number of these paddocks on both farms, we have taken sampl...
We've been busy on farm with our project partners, researchers at DEDJTR, testing and calibrating the pasture measurement gear we will be using as part of the project. One of the tools we are trialling is the Pasture Reader. See below for a YouTube clip of this in action.
The purpose of the monitoring and measurement strategy is to collect data on pasture accumulation and nutritive value as well as water use to assist in the identification on opportunities and challenges, inform management decisions and ground truth estimates and gut feel of our top operators for accuracy.
We have been getting both a CDax and a Pasture Reader calibrated and tested. The CDax is a proven and reliable way of measuring pasture but it's performance is limited in tall crops such as lucerne, as it is a pull behind device an ATV can squash the pasture before it is measured, confusing the results. The Pasture Reader is mounted on the front of an ATV so...
A key component of the project is the close monitoring and data collection of existing farm performance, definition of business goals relating to these areas and development of strategies to meet these goals in conjunction with specialised advice, leading research and access to the latest technology.
The on farm activities that are underway or are being developed to achieve these include:
In depth analysing of current farming system and future options;
Monitoring of pasture and crop growth;
Monitoring of water use; and
Measuring and monitoring of other factors that drive profitability on farm, for example business management, animal management etc
The parameters and methodology to undertake this measurement on farm are being developed with our key project partner the Department of Economic Development, Jobs, Transport and Resources. Sign up to make you sure you get our next newsletter with more information.
