Wired for Science: Understanding the feeding habits of mealybug
Fussy children might be frustrating, but fussy mealybugs could help protect the New Zealand wine industry from grapevine leafroll-associated virus 3.
Lincoln University-owned research and development company Lincoln Agritech says dairy farmers might improve their environmental footprints and profit through two research projects now underway.
Lincoln Agritech got hefty grants in the latest round of the Ministry of Primary Industry’s Sustainable Farming Fund for two three-year studies that began on July 1.
One is looking into using winter catch crops to reduce nitrate leaching loss, and the other into using real-time optical sensors to direct variable-rate fertiliser application in dairy pastures.
Dr Peter Carey, who heads the catch crop study, said research already showed farmers could use nitrogen more efficiently while reducing their environmental footprint, by following grazed winter forage crops with a crop that can be lifted for green chop silage in November. The study aims to show how it could be up-scaled from research trials to commercial working farms, and done reliably and consistently, using various crops under various conditions.
“It can be a win-win situation. But traditionally, trying to sow a crop in the middle of winter is not usually encouraged. Often those paddocks have lain fallow until the next sowing of a winter forage crop or pasture in spring.”
Carey says that rain and leaching from grazed winter feed paddocks can cause a major loss of nitrate.
“It may be only 10% of their farm area, but it may be 40% of their nitrogen loss over that year.”
He says some farmers are experimenting with winter crops but with variable results. They want confidence that it would work, and the study is aimed at producing workable guidelines.
Carey says contractors involved in the study are also enthusiastic, as winter sowing could bring them work at an otherwise quiet time of year.
The study will be trying out new technology -- a power spade plough imported from the Netherlands and designed to manage even wet soils. The spading action helps drive the tractor forward as it works, rather than it relying on tyre traction in muddy ground.
Dawn Meats is set to increase its proposed investment in Alliance Group by up to $25 million following stronger than forecast year-end results by Alliance.
A day after the ouster of PGG Wrightson’s chair and his deputy, the listed rural trader’s board has appointed John Nichol as the new independent chair.
Tributes are pouring in from across the political divide for former Prime Minister Jim Bolger who passed away, aged 90.
The iconic services building at National Fieldays' Mystery Creek site will be demolished to make way for a "contemporary replacement that better serves the needs of both the community and event organisers," says board chair Jenni Vernon.
Agri advisor Perrin Ag says its graduate recruitment programme continues to bring new talent into the agricultural sector.
