The key to using a catch crop to reduce onfarm nitrate leaching is to get it in the ground as soon as possible after winter feeding, says Plant and Food scientist Dr Brendon Malcolm.

Game-changing new research into how plantain crops can reduce nitrogen (N) loss from dairy farms will see upper Manawatu farmers at the forefront of dairy science.

Plantain could ‘save’ some Manawatu dairy farmers faced with cutting nitrogen losses from pasture by 60%, comments DairyNZ.

A world-first denitrification wall at Silverstream, North Canterbury designed to reduce high groundwater nitrate levels is working as anticipated.

Farmers will have to look at their fundamental farming systems if they are to meet future nitrogen leaching limits.

This old mutt has been a long-time critic of the multi-national, tax-dodging, political activist group Greenpeace for its sustained and never-ending attacks on the New Zealand farming sector.

Ravensdown is hoping its Eco-N product for reducing nitrogen leaching from pastures could soon be back on the shelves.

More farmers have asked this year about CRV Ambreed’s LowN sires, as they aim to start breeding for lower milk urea nitrogen concentration (MUN), says product manager Peter van Elzakker.

Farming practices now piloted by Mid Canterbury dairy farmers Grant and Jan Early could show other New Zealand farmers how they can successfully reduce their environmental impacts.  

Research shows that cows bred for low urea concentration end up using more nitrogen for milk protein productions.
