University of Waikato research reveals 2050 drought threats
New research could help farmers prepare for a future where summer rainfall is increasingly unpredictable and where drought risk is rising, no matter what.
But this is no ordinary season – most parts of the North Island are experiencing their driest first half of the year on record.
For drought-stricken farmers on the Hauraki Plains, a scheme harvesting and carting maize stubble to dry regions is proving useful. Supplemented with palm kernel expeller (PKE) and silage, it’s helping farmers fight a feed deficit and keep dried–off cows fed.
To date, the scheme has delivered 1236 bales of maize stubble and about 400 bales of grass silage to affected farmers.
Farmers pay $100/bale for silage and $40-$50 for a bale of maize stubble plus cartage costs.
Waikato farmer and Federated Farmers Waikato dairy chairman Ben Moore started the scheme early last month after getting calls from farmers.
“These farmers couldn’t secure winter graziers to take their cows during winter and wanted me to help them find feed,” he told Rural News.
Moore, who worked for a hay and straw merchant in the UK, decided to approach local contractors and farmers.
With the help of Bluegrass Contractors, Te Poi, John Austin Ltd, Te Awamutu, Neven Granich, Hinuera and Phil Hawke, Hinuera started harvesting and delivering maize stubble to farmers in Hauraki Plains.
The maize stubble is mixed with inoculants to prevent it from going stale.
Moore says with 70% drymatter (DM) and low metabolism energy and protein, maize stubble isn’t a complete feed but can be mixed with PKE and silage to keep cows fed after they are dried off.
He thanks the contractors for harvesting and cartage.
“They haven’t put their rates up and are not out there to make money from someone else’s misery,” he says. “This is a team effort to help farmers facing acute shortage,” he says.
The maize stubbles are harvested from farms owned by commercial vegetable growers Balle Brothers and Wilcox, who plant it as a rotating crop behind their onion crops.
Hauraki farmer Brent Aitcheson purchased 200 bales of maize stubble for his 1000-cow farm in Hauraki Plains.
Aitcheson told Rural News that the maize stubble is another tool in his toolbox to keep cows fed without biting into his winter hay stock.
“You can only feed cows so much PKE, so the stubble helps stretch the feed at a time like this.”
Aitcheson says the Hauraki Plains is suffering one of its worst droughts: last week’s 6mm rainfall was the first in many weeks.
