Trying to find some poultry muck! Considering upping the dap in contrast on some away ground that’s 0/1 indices, had some muck but thought it would benefit from more than 50kg/acre dap?
We have never seen a response to starter P. All MGA trials have shown that where starter fertilisers look as though they are doing good at earlier stages, by harvest the difference has disappeared, so they give you a psychological boost but little more.No, the 50kgish of DAP is a standard application, I would not consider omitting it unless you were on a P index of 4 or something.
For people with indices of 0 or 1 or 2 you need TSP or 0.24.24 in the seed bed as well. Maize needs to find phosphate very early in it's lifecycle, those little seminal roots need to find it to establish the plant. Growing maize on land with very low P or K indices is a recipe for disaster. If land is genuinely that infertile and hungry I would seriously be considering putting seed bed nitrogen in as well.
The availability of phosphate in cattle slurry is not that high.
Was thinking of putting more dap down the spout say 75kg/acre as oppose to 50 to supply mire p but also n?

We have used our normal digestate application - if we had more we would use more - pre drilling. Then we will put a bit of AN on if required (we use the MGA nitrogen predictor which we find works extremely well) and will use Efficient N28 at the latest time we can get the sprayer through the crop.
The main N need is when it is making the cob, and although we have not used Efficient N28 before, the many independent trials the MGA have done show that it is a cost effective way to apply N. We are also using it as the last dose on our winter barleys because I am more worried about the lack of supply of N for next year as much as the price.
We’re sticking 50kg of DAP down the pipe as much muck as I can find before the plough. And adding humic acid. Probably use some foliar k as well as it’s competitive compared to granular currently.
If facing south go ahead.
Needs to be 8 Deg at 4" deep at 9 am for a week, and rising. The figures I've seen suggest that you will be fine, crack on. The earlier you drill, the earlier you harvest, and that's when the problems occur.
How do you incorperate the slurry?What seed rate do you use?50-60 tons slurry incorporated per ha. Then 125 kg NP20-7 per ha with drilling. Thats it. My P quota is less than that, but i take from other crops. It's many years since i couldn't use DAP anymore.
we started drilling yesterday. About 50 days earlier than last year, when we had weeks and weeks of rain.
