Yellow Brassicas

[NYBuckHunter27]

Some of my brassicas are turning yellow in color and look to be growing in at a slower rate than normal, is this a nutrition problem? and if so, what type of fertilizer do i need or is it something i cannot help at this time.

Throw down some urea or N-heavy fertilizer.

 

Did you test the soil? PH could be off so that the plants are not uptaking the nutrients available to them. 

 

Don't get Urea on your truck..corrosive. Also lay it down right before a rain as it is lost to the air pretty easily.

 

If you think that's going to be a pain, then opt for the heavy N fertilizer and spread it. You are probably around 30 days from seeding? Typically when it shows. If so, good time to lay some N down. They love their N.

Either not enough nitrogen or the ground it is in is too wet/ compacted. Is it yellow in spots that are slightly lower than nearby green spots?

I agree with sampotter...  I have had the same problem in wet, low lying areas (even when ph adn fertilizer are in place).. Not to worry,  it may end up a bit smaller, but the deer will still eat it

I take it urea is a powder fertilizer? Is it exspensive? The area deffinatly has the most moisture but its not like the plants are in standing water...

Only about 2-3 weeks from planting as well.

urea is 45-0-0 pettets. , sound like excess water problem . but fert never hurts. about 15 $ a 40 lb bag by me. but any high nitrogen will work. ex. 25 -10-10.

applying urea can be tricky.  I like to disc in my urea before I plant.  Applying urea after plants have emerged you will need to apply right before a rain.  Urea can burn your plants and left on top of ground the Nitrogen will release into the air and not the soil.

I top dress with urea all the time.  It is by far the most cost effective way to apply Nitrogen.

 

I have not noticed any burn on the plants.  As others have said, it is rough on equipment as any fertilizer is and apply before rain, heavy rain is key.

Right now, as others have said, urea just before a good rain. Otherwise, you'll be wasting your $! Sure does give the plants an energy boost!

It also depend on how much material was worked into, or plowed down into the soils. Decomposition of material in the soil can use a tremendous amount of nitrogen from the plant, not making it readily available. This is why I like to summer fallow my fall grain grounds. It allows the soils to break down plant material over the summer months and also rest the soil, so nitrogen, that is introduced into the soil, becomes available to plants life quicker.

Plants seem to be stunted, they seem to be about 10-12 inches and not growing which i cant beleive because we have had a good amount of rain and sunshine. cant see any turnips or radishes yet. kinda worried that they wont have time to grow before the first real frost. Color of the leaves throught the plots seems to be ok still alot of green with some spots turning yellow and purple, i did apply fertilizer about 2 weeks ago seemed to just help the grass/weeds grow more.
