"There has been a lot of interest in exploring the impact of adding plantain to farm systems or including it in compliance reporting."
Plantain offers significant potential benefits. Depending on the proportion of plantain in the animal's diet, less excreted nitrogen ends up in urine, and urine volume increases, resulting in urine patches with less nitrogen – which is better for the environment.
Listen to Lee Piper interview DairyNZ strategy and investment leader Dr Bruce Thorrold about plantain in OverseerFM on The Country Sport Breakfast below:
How large the environmental effect is, depends on the farm's situation, e.g. scale of plantain use, amount of supplementary feed used, soil type and climate.
The FRNL programme was led by DairyNZ and funded by the Ministry of Business, Innovation and Employment (MBIE) and research partners DairyNZ, AgResearch, Plant & Food Research, Lincoln University, Foundation for Arable Research and Manaaki Whenua-Landcare Research.
First, FRNL assessed the impact of Ceres Tonic plantain and other forages and identified that plantain reduces nitrogen leached.
Overseer spent the last year working with AgResearch scientists to translate the FRNL findings into OverseerFM.
"Including plantain in Overseer ensures farmers can have the good work they are doing acknowledged as part of compliance processes," said Dr Ina Pinxterhuis, DairyNZ senior scientist and FRNL programme lead.
Further research was planned to better understand the effects of plantain on nitrogen processes in the soil, said Pinxterhuis.
