Information on nutrient losses from the Foundation for Arable Research's (Far) flux-meter data-collection project will have applications for Otago and Southland arable farmers.
Far heard earlier this month it had been given $485,168 for its ''Protecting our groundwater: measuring and managing diffuse nutrient losses from cropping systems'' project from theMinistry for the Environment's Freshwater Improvement Fund.
The $1million project has been under way for three years in partnership with HortNZ, Ravensdown, five regional councils and Plant and Food Research. The balance of funding comes from industry and regional council partners.
Plant and Food Research collects, manages and analyses the data.
Far's research manager for farm systems, Diana Mathers, said they installed drainage flux meters under arable, vegetable, sheep and dairy grazing farms to measure and monitor nutrient losses from the different cropping systems.
Although the meters were on farms in Canterbury, Hawke's Bay, Manawatu, south Auckland and Waikato, the information collected would be useful for southern farmers, she said.
''We were funded for three years through the Sustainable Farming Fund to put in flux meters under cropping rotations,'' Ms Mathers said.
''They are buried one metre below the surface under crops and are collecting data on drainage volumes and measuring nutrient losses.
''We are now at the stage of starting to get some useful information.
''We had to have a decent run of data to see what the patterns are.
''A lot of the results are not necessarily region-specific and we will be looking at them and thinking, how does that apply to other regions?''

She said analysing the data would provide insights into where farmers could improve their farming systems and look at what they do and do not have control over, like the weather.
''In the first three years (of the project) the East Coast, Canterbury and Hawke's Bay had very dry years, so there was not a lot of drainage and we did not get a lot of information.''
