On-farm trials to fine-tune nitrogen needs for wheat

摘要

A new on-farm project is set to kick off this spring aimed at giving better advice on nitrogen fertiliser rates needed for growing high yields of winter wheat. Some 18-plus wheat growers are being sought to take part in these trials, which hope to push up potential wheat yields while reducing leaching losses. Researchers believe some farms may need more nitrogen then currently recommended to achieve higher wheat yields while others may need less.
