Precision farming a key element of next Better farm crop programme

Precision farming technology will be a key element of the second instalment of the Teagasc’s BETTER farm crop programme. This is according to Teagasc researcher Dermot Forristal, who outlined the objectives of the new programme at today’s National Tillage Conference in Kilkenny.

Forristal said: “The emphasis will be on determining its role in improved management of crops using spatially variable technology.”

He outlined the work will have three specific components: Firstly to quantify and investigate within field variability. Secondly to evaluate appropriate crop management responses. Thirdly to demonstrate precision agriculture technologies.

“Selection of growers will be from those with an interest in or previous experience of precision agriculture.” On the selected farm yields variability will be mapped and analysed to find possible causes, which in turn will be investigated, he added.

The programme will then involve the adoption of a number of input strategies on high and low yielding areas of fields in replicated trials.

Forristal continued: “This will help determine the optimum response approach to variability, as measured by its impact on crop yield and margin.”

He also outlined the new programme will attempt to demonstrate and possibly use newer technologies, such as the satellite and proximal crop sensing technologies in crop management trials.

He said: “The plan is to demonstrate current technology and find out whether gains can be made from using variable crop management systems. He added: “There use will also help to focus future research efforts in this area.”

In a detailed presentation, Forristal outlined there are two main divisions when it comes to precision agricultures use in tillage farming. The first area is managing spatial variation meaning managing the differences in yield within a field. The second area is concerned with machine guidance be it auto steer or headland management.

Forristal commented: “When the concept of precision agriculture was invented in the early 1990s many thought it would solve all our problems. It didn’t, they were unrealistic expectations for it at that stage.”

He added: “While the technology has improved in many areas, the interpretation of the data it produces and how we respond to its findings has seen limited progress.”

He concluded: “While the concept is valid we must challenge the fixed blueprint approach, managing variability is challenging but its aim is valid.”
