Nitrogen in Maize drill

Soil results show no need for and extra P and K for maize so just 150kg/ha seed bed Nitrogen recommended. How much AN can be put down the spout on the drill without negative effects? Any advise appreciated. Thanks

What are your P and K indices?

Most people I had growing maize applied no extra nitrogen because it didn't seem to provide any benefit. The 50kg of DAP seemed ample. Don't forget sulphur.

Indices of 2 & 3 for p and 2 for k. It’s had plenty of Fym and sewage sludge as well. Just wondered what was the best way to apply N and How much I could get away with putting through the drill. Thanks for the reply.

But the crop will have 170kg/ha of readily available phosphate. I wouldn’t personally waste money on expensive fert to wash into the soil when organic matter has been incorporated

I have gone back to fertiliser down the spout this year. Have avoided DAP for years because of high phosphate indices, also having high ph soils in my view applying phosphate is unnecessary. I have used 150 kg/ha of 27.0.0 37s. It’s not out of the ground so I am waiting to see the results.

I have always had issues with early vigour of maize. I don’t think the quoted numbers really relate to the high ph/ shallow chalk soils I have. At this time of year the fields go white and I have a theory this slows warming of the soil. Not a problem this year as the soil was consistently 12 degrees a fortnight ago, but is the reason I wanted to try n down the spout.

The placement of the phosphate is important. I have seen cock-ups with starter fertiliser on all kinds of soils, even on those with high background fertility, those seminal roots need to hit phosphate ASAP or it stunts the plant.

what would you recommend alongside purely FYM, purely cake and mixture?

our independent agronomist has been pushing the last few years for us to pull all supplemental nitrogen applications. On dairy land that has been heavily manured he says it rarely helps.

Top cereal and oilseed growers honoured at the Yield Enhancement Network Awards 2021

Despite an average growing year for most crops, many growers managed to go above and beyond their predicted max yields, with Lincolnshire grower Tim Lamyman taking the top spots for his wheat yields and his world record breaking winter barley yield.

The highest cereal and oilseed yields achieved at harvest 2021 were announced at this year’s Yield Enhancement Network (YEN) Awards on Wednesday 24th November at the Croptec Show. With award presentations by Tom Bradshaw, Vice President of NFU, 24 farms took home the evening’s top awards for highest yield and highest potential yield achieved for wheat, winter and spring barley, oats, and oilseed. The 2021 winners came from all corners of the UK, as well as from as far afield as Finland and New Zealand.
