Drilling seed and Fert together?

[RHFW]

We have been using DAP down the spout with seed to good effect but with current prices and reasonable fertility is CAN an option? Or will it gather too much moisture and block the seed spouts?
Having asked that, what is the most reliable DAP product for drilling with seed? Certain DAP products have caused issues and time lost cleaning out the drill spouts

 

[Flatlander]

Even with good phosphate levels in the soil some 30 ish units with the seed boost it growth. The salt index is one thing to keep in mind. Varies by source and some years when dryer it can be a serious issue with seed burn. CAN I’m not familiar with but assume its ammonium nitrate with calcium. That I’d be very careful with putting with seed if your drill is in a narrow band. Seed bed utilization can dictate your usage fir N in the seed row. Briardcast the N and incorporate it To stop it gassing off.

I have ordered a grain/fert drill. Can you make your own dap that works as well with nitrogen and phosphorus? I know Dap is a chemical reaction with phosphoric acid and nitrogen so does this make it more available?

We are putting triple 16s down spout this spring with seed.

 

[Flatlander]

From my experience it’s nit what you use it’s the amount. I used to drill with a six inch opener on 12cinch spacing,this I could safely use 5o units of N and 55P along with the seed. Now I use a disc drill with about a 3/4 inch spread I can only go with P. As far as I understand DAP is diammonium phosphate. Which is higher in N and slightly lower on P than map. 18-46 as opposed to 10-52. Seed safety is compromised from the higher N if place in close proximity to the fertilizer. For combining the seed and fertilizer MAP is a safer option. Soil moisture plays a big part in the amount of N that can be seedrow placed. Canola can tolerate very little N and limited amounts of P. For my drill 25 units of p is the limit due to the salts present in the fertilizer.

Some say it’s more available because the nitrogen breaks the phosphate down to make it more plant available BUT if your wanting early uptake of the P making or putting that phos in a position that’s a hot zone for roots isn’t going to help.

A big no-no in the NVZs (currently 55% of arable land in England).

I’m sure it’s ok in the spring...?

Haven't finished autumn here, yet.

In the 1960,s /70,s MF drills did most spring crops with 20/10/10 down the spout, the row that blocked its fert could be seen from space!

Wouldn't it be better to apply a biological stimulant to better activate the nutrition in the soil than use fertilizer?

Do you know of one that works?

I've had some good results with Consortium Z and Bugboost in sugar beet and potatoes

Did you reduce your fertiliser rates accordingly? Was there a cost saving?

The main motivation was Rhizoctonia control in the spuds, where it has paid handsomely over Amistar for some years now.

This is the first year of using it in the beet, but our October lift yielded 32t/acre, which is about 5t/acre above where I'd normally expect.

Fert stayed as normal, but there is certainly scope to reduce it a bit. P supplied by fym in the beet, with Sylvinite supplying the K & Na, alongside polysulphate supplying K, Mg, Ca & So3. 60kg N applied immediately pre drilling via Lithan, 50kg N 3 weeks later via liquid.

Still a way to go then before a biostimulant would/could replace any fertiliser by the sounds of it.

Look at the increase in yield though. 5ton more beet is over a hundred quid an acre. Even a 5% increase in marketable yield in spuds is nearly double that. Significant.
I'm sure there is scope to lower fert applied, but margin is king. Higher fert prices tend to encourage lower fert rates, so we'll see what happens.
longer term I think strip til will feature here, which will make it easier to use Consortium on other crops as well.

We strip til here and find fertiliser in the row has transformed spring cropping on heavy land. Crops are hedge to hedge even and are using less P & K as it is concentrated under the crop. Yields have increased and fertiliser rates have dropped so happy in general. Have micro granular applicator in drill as well so interested in bio stimulants as well...

What is your drill of choice? That sounds really encouraging, well done! Any pics?

Our drill is seed only. If I blend DAP with our seed will it be ok or will it separate as it is being sown?
