So I have an older single shoot drill and am planning on sowing flax. I am planning on putting some S15 or MESZ with the seed. I had thought about banding or broadcasting the rest of the fertilizer ahead of the drill. But now I am thinking of top dressing with liquid a little while after its sown. My question is, how important is it to have the total amount of fert available right at the beginning of plant growth in flax.

I top dress wheat and canola with 28-0-0 and and it works for them but im wondering how it would work for flax.

Thanks for the help.

I used streamer bars to put 28 on just after it was up in the past and had very good luck with it. You need a rain pretty soon after though, just like the rest of the crops. Flax is the same as every other plant, the nitrogen utilization through the growing season is not linear. You don't need much to get it going, demand comes on as the plant grows.

Im putting 50lbs acre for seed. In the end I want to have 80-85lbs N. I am limited on my phos rate with the seed but I would want 35-40lbs available to the plant.

Thanks for the opinions guys. I dont want to band because of our moisture levels. I think I will top dress with liquid later.

35-40lbs of phos? I don't think flax is very responsive to phos, unless your soil is very deficient? Flax depends more on mycorrhizal relationships to get phos from the soil. Thats why you're not supposed to plant into canola stubble, because canola doesn't require/support mycorrhizae

Yes it is probably too much phos but Its there had good luck with that rate before and what isnt used this year will be there next. I am no expert by any means. Just what I am shooting for.

WE have grown flax for many years now and we put down 75 pounds of N as nh3 in the fall then 45 pounds of 11-55-0 with the seed single shoot on a 3" band . Never had any germ problems and we know that the P isn't used with the flax that year but it will be there for the next .Also think the bit of N helps as a starter fert .Usually seed at 50 pounds per acre . Have never top dressed flax and would be a bit concerned about burning it as some chemicals will hurt it pretty bad when it gets bigger .

Single shoot 60 lbs mesz, 45lbs of flax and top tress 140lbs or 65bls act. 46 soon after seeding could do it before but I like after because of wheel marks grew a couple of good ones that way! good luck ps then hope it rains!

Foliar apply an orthophosphate at correct timing. Available to the plant and travels through the plant being usable to the root system. 15 lbs phos with the seed is max with flax on narrow openers. Send tissue samples and when spraying you can add whatever else in micros you are short on. If it looks like a drought and crop is going to be crap you have your money unspent. Flax requires lots of moisture and is risky. Very shallow rooted.
